  3. Wayne Schultz

    Easy to handle size, not too heavy, plenty of power and long lasting charge. Also recharges quickly. Highly recommend.

  4. Drew Wilson

    I read reviews. I got mine in and did some testing. Not having issues like others state. Holds full charge and no issues found. No I do not work for this company but if they would like to send me a few larger cap batteries for this review I wouldn’t mind 🙂

  5. ira west

    works fine

  6. Katt

    Power wheels mod for dune racer. Extended wires to the front hood compartment. Way longer run time than stock battery

  7. Susan Robertson

    As advertised. Wanted two batteries for my Pride go chair. This one fit perfect and was easy to install.

  8. Faye T. (verified owner)

  9. Steve Remick

    No opinion one way or the other still new

  10. S Rudowski

    Did the trick for mobility scooter

  11. Bruce Smith

    I use this battery to power my clay pigeon thrower and wobbler which is usually on for hours while we shoot. The battery holds up well. I only wish they would make a battery box that fits this battery

  12. Neat

    Used for Whirlybird. Purchased battery box as well.

  13. Toby

    The battery arrived on time and very well packaged. Fully charged on arrival.

  14. Jonathan Burnett

    Good battery at a fair price that makes my APC UPS work again!

  15. Navigator

    This battery has a larger capacity than the original & yet fits into the case perfectly. The battery charged quickly and has stayed fully charged for a while now, so I think it is a 100% improvement over the old battery that would not hold a charge for more than a day . Happy with the purchase – a replacement jumpstart unit would be about 79$ and this was $36; I highly recommend going the battery replacement route as it only takes about 15 minutes to replace the battery yourself!

  16. Dino

    Used for a couple of hours to run an electric clay thrower. Rolled through 200 clays and when I checked the charge it was still pretty full. Isn?t too heavy and the battery feels well built

  17. John Walters

    Perfect sise

  18. Albert Levinson

    works well on our champion clay launcher, lightweight portable and holds a good charge

  19. Scotty

    A perfect replacement for my portable compressor!

  20. Russell Guest

    Bought this battery to run skeet throwers. Battery performed as advertised. Light weight and holds charge well.

  21. Look around you

    Battery arrived quicker than expected and in perfect condition. I put it on the charger and it registered fully charged within about a half-hour. Can’t comment on longevity because it just arrived, and have no clue what ‘Sheerness’ might be vis-a-vis a battery. (?!) This will be going to a remote cabin as part of a very small solar power system. It will replace a similar battery that has begun so show its age after ten years. We hope this one will serve as well.It certainly appears to be, and topped up quickly, as advertised.

  22. Jerry H. Adams

    I purchased two of these little batteries to power a backup system for my desktop computer. I do not need it for more than a couple of minutes, just long enough to save my work and turn the system off. My area is legendary for its voltage spikes and other problems, so this backup system is a real godsend. I like the size of the battery, and so far, it has done everything I need…

  23. Ed Schaffner

    Light weight, surprisingly long life, great value. No idea what sheerness means

  24. tell you

    The battery came quick, full charged and ready to use, I haven’t had to charge it after several hours of usage.

  25. Frank B.

    Have gotten these batteries in the past and they hold up well, although longevity of this battery have not been proven yet.

  26. It is a wonderful day!

    I use this battery to run a small 12 V DC water pump that circulates water in my hydroponic garden. The battery is charged by a small (50 Watt) solar panel. Water is stored in an attached 5 gallon bucket on the A frame hydroponic garden and keeps the plants in water.The battery arrived quickly and was charged. It was well packed and when I installed it using the solar panel for charging it ran the little pump nicely.I put the battery in a weather proof container and strapped that to the A frame hydroponic garden system I have.I have had this for several weeks now and have discovered on very cloudy / overcast days the battery may not get fully charged. I don’t think this is an issue with the battery or the solar panel since everything works again on the next sunny day.

  27. Ed D.

    I bought this battery to run my Champion skeet throwers. They operate well with a deep cycle battery. I was using my old trolling motor battery that weighs 50 lbs. Moving this 12 lb Mighty Max battery is so much more convenient and it provides the same power requirement for the throwers. Very nice little battery.

  28. Gary Yates

    This car starter/compressor/inverter & battery charger was given to me. It would not take a charge. I replaced the original battery with this one. It is the same size and amperage. Terminals also matched. Works perfect. Now I have a $165. Unit that cost me the price of this battery.

  29. DDock

    I have a Black & Decker car multi-tool that had one of these batteries in it that was dead. Replaced it and it is back up and working! Can’t say anything more at this point.

  30. Donald Sherman

    Worked well but did not hold the charge as long as I was told it would.

  31. Bruce Trice

    I like the price, size, and battery terminals. Dislike the number of AH but over all good buy.

  32. Rover100

    These arrived ahead of scheduled delivery date, exceptional packaging and arrived in excellent condition.Exact fit for my UPS unit and functioning perfectly.

  33. Yvonne Cross

    Quick service and delivery

  34. Felix Skarpa

    It was same size as the old one.

  35. Thomas C.

    Works as needed, no issues for at least 2 hours of use first time out. I also purchased a trickle charger with it, but battery arrived fully charged. So far, so good.

  36. Crystal

    Great

  37. Wayne Holder

    Good battery working on my skeet thrower. No problem with this.

  38. Ed

    Just what I needed fits and works fine

  39. Ez2bme

    Not sure what sheerness has to do with a battery but, sure it was great.Longevity, to early to tell. The first one is 6 years old and still kicking.

  40. Kenneth w parks

    nice size to use on my skeet thrower

  41. yoyo

    Exelente

  42. Susino

    Exactly what I was looking for. Very satisfied with my purchase. Seller is amazing my package was missing and seller replaced with no issues.

  43. jon wagner

    using this battery to run 4 graphs on my boat , have run it 11hrs straight with minimal power drain . tested 12.8v at start of day and after 11hr. was at 12.6v. its AGM fully sealed technology allows you mount battery upright or on its side .

  44. Carmen Figueroa

    Great Product, over all very satisfied.

  45. Paul W. Kirst

    Arrived ahead of schedule, undamaged and fully charged. Time will tell if it is a good value.

  46. Noeum S.

    Strong and long life battery

  47. C17Rocky

    The size & dimensions of this battery matched what fits my field & brush mower. The battery came fully charged & easily starts my engine. My concern is the weak packaging. The cardboard box was strongly banded, however the cardboard box was poor quality with inadequate inside packing. The thin styrofoam pad on the top of the battery was crumbled & one of the top corners had crush damage which does not appear to have breeched the battery case.

  48. Carl

    mounting these two batteries on my boat made size a big concideration, the two fit together in one hole. the two batteries ran the trolling motor all day long, pulling by 17 foot boat up stream and down and was still showing full power at the end of the day. Only thing is that there is no OFF switch to the motor, it has to be disconnected from the batteries.

  49. Laura Elkins

    Works like a charm

  50. John Schneider

    It was an excellent replacement for my DR truck

  51. T Weatherton

    Arrived on time and undamaged!

  52. Customer

  53. PTandJB

    Purchased this larger battery to provide all day power to fishing sonar electronics. Four seasons done and battery still going strong after maybe a hundred charges, using Optima Digital 400 charger for maintenance. Drilled four holes in plastic flaps to attach rope carry handles to lift out of boat and carry around for various household applications of 12V power. Started 5th season and still working great, kept Humminbird Helix 7 running all day yesterday.

  54. Horst Thompson

    used batteries for golf caddy

  55. BEWARE

    Good size for a clay target thrower-was even able to mount it on the thrower body.

  56. David R.

    This battery was perfect for my 18 yr old generator. It fit the rack on the generator and cranks the 18hp motor with just one push of the button. Not sure about the longevity, but will try to write a follow up review in a few months.. I did purchase a small battery tender and keep it hooked up to the battery, so I’m not expecting any longevity problems.

  57. Customer

    Great price and quick service.

  58. dennis

    Battery is a good battery that seems to last.i did not rate the longevity because I have not use it for a long time.

    The correct part arrived quickly. It was a quick, simple battery swap. The battery fit perfectly on my Champion generator and has worked since.

  64. Schmitch

    The only thing I can really say about this is that it works. No issues so far. It works when it’s cold, it works when it’s warm, it’s not too big, it’s not too heavy. It powers my Champion WheelyBird perfectly.

  65. SS

    The battery posts for connections could be bigger.

  66. Grego

    Battery arrived fully charged and was an exact fit. Would purchase again.

  68. Alan Nestico

    Ordered 1st battery in 2017 to put on my brush cutter. Lasted 3 1/2 years. Often sat for months unused without supplemental charging, but always fired up. Well pleased with longevity.

  69. nytowl

    Used this to replace the old battery in our Cen-Tech 4-in-1 Portable Power Pack (jumpstarter). Works great!

  73. kenneth m leydig

    Product came in short time , and was what I expected

  74. Warren Gaggin

    Battery terminals were different from the original Briggs and Stratton generator. Battery terminal difference necessitated installing battery upside down in order for grounding cable to reach terminal. Fortunately it?s a sealed battery.

  75. R. Scott Chapin

    This was a good fit to replace a Stanley auto jumper battery that died. It has a greater capacity and kept me from throwing an ?unserviceable ? tool away.

  76. Shane Crouch

    It came fully charged, with terminal nuts and bolts for install. 10/10 would recommend.

  77. Fred G.

    Fit my generator perfectly. Came fully charged and started the motor easily.

  78. Toby McGuire

    Great battery. Does the job. Holds the charge well. Used for my Champion Wheelybird 2.0 Clay Thrower.

  79. Peter J. Nunnery

    love it so far

  80. Brenda

    We have used this battery with clay througher

  81. Victoria Jenkins

    I bought this to replace the battery in my jump starter pack and since then its helped me out start my Jeep and keep the tire inflated, a huge life saver!

  82. Gretta

    Writing on box (deep cycle) disagreed with the battery which has written on it Do not let drop below 10.5 V) They are fixing it, they said.

  83. Greg Clark

    It started my generator right up

  84. Robert Richardson

    Nice

  85. Margaret Hosseini-Browder

    I love it! Lasts all day and have it for over a year and still going strong!

  86. Margaret Hosseini-Browder

  87. David

    Needed to replace the batteries on my wifes mobility scooter. These fit perfectly hold a charge for long days at Disney and still have reserve power left. Key to getting the right battery is to make sure they are Deep Cycle, standard batteries just won’t cut it.

  88. Sabrina

    It holds great charge. Easy to plug up to a battery charger. We use it for our trolling motor and it works great lasts the whole time we are fishing.

  89. Web Customer

    Good price, works good.

  93. Zach

    I bought this as an auxiliary battery for my fishing boat. I run a gps/fish finder. Nav lights. My radio. Spot lights. And charge my phone from time to time. Overall it performs pretty good and it?s small enough to fit up under the dash. I might buy a second one.

  94. Lee Robinson

    Good battery that is easy to transport

  95. Joe Wilhem

    Only used it once so far it seems to have the power needed to propel mu Wheely Bird trap machine.

  96. Russell B.

    Fit perfectly in Stanley jump starter pack.

  97. Juan

    Fired my generator right up.

  98. Kerry D. Sarchet

    Perfect replacement for my DR 60? grader. Battery raises and lowers the lift on the grader.

  99. TERRY O JONES

    The mighty max battery, work fine when I received it and with installation to my home made solar generator for camping.It work great as a temporary blackout, generator kit.Using a 12 – 24 volt solar panels controller to recharge the two batteries in the kit. It ruptured along the seam after charging for 1day and warped. I brought 4 of these batteries for my solar generators.

  100. Blargh

    I have about a dozen Mighty Max AGM batteries for various projects and ONE developed a leak. Mighty Max replaced it in 2 days.I’ve owned other brands of AGM batteries but I’ll be sticking with Mighty Max from now on.

  101. Shirl Customer

    Good product

  102. Customer

  103. Glenn D. Hughes

    Seems like a great value so far

  104. Carbonhead

    Battery arrived with a good charge, and well packaged. Terminals are rock solid and clean, with rubber covers on them. Zero damage. Exact replacement for the factory battery. Will buy again if needed.

  105. Jeanie

  106. Tim Nummerdor

    Ok

  107. RADAR

    Working perfectly so far, impressed that it came already charged!

  109. David Jessop

    Needed a battery for my solar light system for my driveway. Powers my light very bright and works great with my solar controller. Hopefully is will last but time will tell. For now, it was a great buy.

  110. Alma

    Long lasting. Easy install.

  111. Jeff M.

    Battery was a direct replacement and fit great. I don’t know yet how long it will last, actually kind of a silly question for something new.

  112. Michael L.

    Put this in my kids power wheel about 2 months ago and haven?t charged it since. Very surprising.

  113. Charles H.

    Good standby battery at a good price

  114. Duane Feick

    I hope this lasts a long time. Too early to tell.

  116. RD

    Put this battery on my Honda 300 four wheeler almost a year ago and it’s still working well.

  117. R. Edward H.

    Installed this battery (2) in my old Homelite mower. Batteries charged fully in 15 minutes. Have mowedlawn several times since replacement and mower battery indicator drops just 20% after 45 minutes eachtime. From experience, these batteries should last about three to four years.

  118. Gary Tetreault

    Great replacement and even better value than local retailers

  119. Delbert

    It works

  120. SamC

    Used this battery to replace the original one on my DR Power mower that is 15 years old. I have just installed it, and it does start the mower AOK. Now the question is… Will it last as long as the original did? Only time will tell on that one. I will also state that the cost for this battery, $38.99, is a whole lot better than the $64.99+ that I saw for the replacement battery from other places. So value for the $$$ = 5 stars, Easy to install = 5 stars, however Longevity = unknown… Only time will tell.

  121. Randy S.

    This is the same type of battery that came with my old Zappy Electric Bicycle. It was getting kinda slow so I order this to replace it.Seems like something inside went very wrong. Unable to get power in or out, it reads 6v on my multimeter, but it will not light my test light. Even after 24 hours on a battery charger. Fortunately, it was under a year old so under warranty. They said they needed the date code off it, but there wasn’t any such thing on my unit. Didn’t seem to faze them. The folks on the phone offered to send a new one, I’ll update when it arrives.EDIT: New battery arrive today, only took a few days. That’s great warranty service at least. Bumped up a star

  122. jeffrey banier

    thanks

  123. ed

    Works great

  124. Sammy Rivera

    Been using it with my battery pack

  125. William R. Gee

    This was the second time I bought a set of four batteries for my APC 2200 UPS. Both sets lasted less than two years. Not a good value. They should last four to five years. I will be trying another brand, though it might not make any difference. I suspect they are all made in the same factory.

  126. Sergio Diaz

    Very good thanks

  127. Mario DaSilva

    So far, I have used my battery with my clay thrower for 150 shots and it had more power. The battery is small, easy to transport, and it seems to hold up for a long period of time.

  128. Philip Day

    Works great with my wheels bird 2. So far I can launch 90 Clays and not run the battery out.

  129. T1704

    Perfect for what I intend to use it for (Power lights on a go kart).

  130. PJF

    Used in power wheel grand kids. Had to make adjustments to make it fit, but I knew that before purchase. Works great and at half the price of Fisher price recommended battery.

  131. Gobert

    Battery pack jump starter

  132. gstid

    Perfect replacement battery for my electric start generator

  133. photo guy

    I bought this for my trap throwers, using two throwers at a time threw 150 birds no problem. I cycled the throwers another 100 times each, to test the battery, no problem. When I came home to charge the battery it was only down about 25 percent, very impressive.

  134. Customer

    Product as described and delivery as promised

  135. N Gray

    Good value to replace cheap and nasty original battery in Harbor Freight battery pack. I was worried about the fit as no-one I could find locally had anything like it, including Harbor Freight!! I will be back in a year fir further review if the battery fails!!

  136. nick belseth

    Bought it for a battery charger, worked great!

  137. Judi Hardin

    Great

  138. Eric Halter

    I purchased the battery for skeet shooting. The product lived up to the representations and survived a long day of skeet shooting.

  139. Bob von Spiegel

    Perfect fit.

  140. Eve

    Perfect replacement

  141. Barbara B.

    Used for so many things. A great way to buy brought to your door ready to go.

  142. Prime Time

    I bought this for a DR brush hog. Batteries only last 2-3 year in it, so I’ve purchased several over the years. This one was less expensive than batteries I’ve purchased in the past, but it fits and works just as well. It was a good buy.

  143. Customer

    I like the smaller size of these 18 Ah batteries. Takes a bit longer to fully charge a pair than a fullsized battery. Good price.

  144. Spencer

    This battery is great last a long time and is small so you can put it just about anywhere

  145. J. R. Stewart

    The battery comes with screw terminal binding posts, that supports the 12AWG solid wire connected to it. I have test-run the radio equipment at short-burst full load, with no loss or degraded audio and/or strong RF signals. The battery fills-in the gap when the drain/load exceeds the external power supply and runs as a UPS backup for my 10/12 Meter Amateur radio and Galaxy CB radio. Not sure of the duration yet.

  146. Ryan

    Bought this as a replacement for a Power Wheels Kawasaki KFX ATV. This was 2/3 the price and twice the aH of the OEM battery. Had to modify the battery area a little but it took a few minutes and was easy. Added an inline fuse for mine just to be safe. You can even cut the battery connector off the old battery and use it with this one. Came charged. Lasts a long time with the kids running it hard.

  147. Olivier Couture

    Best bang for the buck, no issues after 10 months of use

  148. Joseph Valiga

    I bought this for my generator so it isn?t used to often but it installed perfectly and works well.

  149. Customer

    Likes: robust design and a lot of power in a compact, easy to transport, size. The leak proof case is a definite plus.Dislikes: The bladed terminal configurations. I use alligator clips so round posts would work better. This is a minor concern and the reason I gave it 4 out of 5 stars.

  150. jim wood

    Great Replacement

  151. sergio monfort

    So far so goodWorking fine doing what was expected

  152. mitch114

    received battery as promised ,charged battery and it holding the charge ,have not tested it with a load yet

  153. Jay Pea

    Works perfect with the Champion WheelyBird Auto-Feed Trap, and I would assume all other automatic clay throwers. All day battery life, in a pretty small package. Much easier to use, lighter, and smaller than a ‘regular’ car battery for this purpose. It’s probably only 15lbs (6.8kg) and it’s only 7 inches wide, 7 inches tall, and 3 inches deep. This is the one to buy for a clay thrower!EDIT: 2 years later and it?s still perfect. Launched over 500 clays the other day of the course of 4 hours or so, and it seemed to still have way more life in it. Buy this one for your clay throwers!

  154. Tony Kiene

    Pleased with the speed of delivery and product is working. I hope it last longer than the last set of batteries order. First set only lasted 9 months. Hope these last more than a year.

  155. Sr Ken

    Just received my battery. Perfect fit for my jump starter/ air compressor. Should get many years more out of my air compressor.

  156. RR in Texas

  162. Customer

    Met requirements.

  163. Heidi Barber

    Is exactly the same as the ones I had in our electric mobility scooter!!!! Didn?t have to go pay double for the brand of the scooter like they say to do!!!!

  164. Bob

    I purchased these for my wife’s mobility scooter. I installed them and used them right out of the box. They had a strong charge that we used for several days. I did finally charge them. They seem to hold a charge much better than the original batteries. Very pleased with them and would recommend them to others.

  186. Mel Schudmak

    Excellent battery

  187. J. Campbell

    Temperatures in the teen took out the battery on my Rigid 6800 watt generator. This solved the problem in minutes.

  188. J Griggs

  190. William B.

    It works great for my Trap thrower. Shipping was awesome. I can not give it 5 stars until I have had it for a while.

  191. Clark Howle

    Great value, Dry cell, arrived with nuts and bolts to make a good connection, size fit my project.

  192. Russ

    The best price on the net! Great deal

  193. Bandit

    used two of these in my battery backup. they are $20 cheaper than the replacement knock offs batteries and the work just like the original

  194. chickychick

    worked perfectly for the Wheelybird skeet thrower

  195. Edward Eaves

    Excellent alternative to larger marine type battery. I have used it several times in my clay pigeon thrower. So far it is holding up great.

  196. fireman

    very good battery

  198. Jeff Stamper

    As expected.

  199. Keeponrollin’

    Good product – bought this battery for replacing a 8 yr. old battery in our Black & Decker Jump Start for jumping dead car batteries.

  200. TheWebWalker

    Works fine, no complaints

  201. William

    Shipped fast, great price at just over 50% of my local retail suppliers price. Has more power than the original battery in my jump starter. Worked great!

  202. Robert Falk

    So far this battery has met my expectations

  203. brenda S.

    Nice Battery Good Price. Works good on my generator

  208. jake

    This battery works excellent as a kids powerwheels ride on toy battery replacement , hasn?t failed me in yet in 3 years. Has enough power.

  209. J. johnson

    Perfect fit in my old Schumacher battery booster/ power supply. New life and remarkably easy to install.

  210. David L Pierce

    Works as expected.

  211. Gary Hosker

    Really pleased with this battery.

  212. Patrick

    Great battery that comes in a compact size and has plenty of capacity.

  213. StacyO

    keeps good charge, lasts

  214. Kanab Fisherman

    Was an exact replacement for the old battery in my Husky jump starter.

  215. Cigarjohn47

    Great Product. Just ordered two of these. They replaced my last APC Smart-UPS 1500 battery back-up system. I usually get a good 4 to 5 years out of these before needing replaced. They hold a good, long charge and much cheaper than the APC Battery Pack. Worth the purchase for me.

  216. mark m.

    good battery

  217. Bob

    Battery was exact replacement for my Generac generator. Arrived quickly and works pefect…

  218. Hobson Elrod lll

    Looks good

  219. breezy

    I’m not sure what to say, I don’t know anything about deep cell batteries. I purchased the Champion Workhorse Trap and recommended this battery. I researched it, found nothing wrong, then bought it. It charges easy, is very portable and it runs my Trap thrower for hours and hours. I’m glad I bought it.

  220. Wayne

    perfect replacement

  221. Ronald M..

    bought this battery as a replacement for an emergency generator , had the exact one I needed (amp/hr and size was critical) , shipping was very fast , I’ve got this one on a battery tender float charger so hopefully it will last .VERY happy with price and purchase.

  222. Leonard

    So far so good. Using it on my solo Skiff to run lights and fish finder.

  223. Web Customer

    good

  224. Customer

    good

  225. John (TheFrugalFatGuy)

    I’ve been using this battery in combination with a trickle charger to power the fridge on my camper in the backyard (just DC, not the converter). Works great for that. It will be easy to remove and bring inside when the summer is over and I can keep it in good shape all winter. I wall also use this next summer to start my lawn mower if the 7-year old battery in that fails completely by then.

  226. Clair Prutsman

    Very pleased with the battery. Hooked up to portable generator and immediately started engine. Works better than the original battery.

  227. Customer

    Very pleased with the battery. Hooked up to portable generator and immediately started engine. Works better than the original battery.

  228. Jackie and Debbie

    Does exactly what its supposed to do.

  229. Shoshane

    Does exactly what its supposed to do.

  230. Longhorn

    good price dose the job

  231. WIZARD D

    Seems to be a good quality AGM SLA battery. This is not 19AH, it is 18AH. The serial No is a little misleading. It still has the size and shape of the 19 AH version. I installed this in my 10 year old Black&Decker power supply/portable car starter. It works fine. I can’t attest to durability right now, I will revisit this review if it fails prematurely.

  232. Michael Haughey

    This battery was the exact replacement for my stand by generator.

  233. Erica Anderson

    first time we used it it held a charge for a couple hours. The second time it did not last that long. Keep it charged if you are wanting to use it regularly. We hooked it up to a battery maintainer so if it is just sitting and drains the battery the battery maintainer will make sure it stays charged.

  234. Richard B.

    Excellent product. Perfect fit for replacement of the battery that came with my generator. Started my generator immediately during a recent power outage.

  235. Berkesch

    Fantastic – powerful, light, and compact.

  236. Glenn H.

    I have this battery powering outdoor lights. It is charged by a single 100w solar panel. Runs 10 or 12 pathway lights every evening. The battery arrived quickly. It was well packaged and it was fully charged. Bolts and nuts for cable attachment were included. Probably not your typical use for this battery but it works well for mt application.

  237. Scouter III

    The two batteries I ordered arrived on time and in excellent shape. My NOCO G3500 Genius charger indicated each battery was fully charged about 3-5 minutes after putting the charger on them so they were both essentially fully charged on arrival. I plan to use these as backup power for my HAM radio equipment. These batteries seem to have overall good reviews and that is why I chose them over the competition. I will update my review comment if they perform less than expected.

  238. Customer

    Used it 5x and haven’t had to charge it yet. Great product!

  239. Al Tyler

    exactly as OEM. Fit perfectly and holds charge .

  240. Lloyd E. Anderson

    Battery worked fine for my needs!

  241. Dan Cristian Manea

    I love it, I bought it for my generator and works great!

  242. Customer

    Replaced a battery for Stanley Jumpstarter JC509. Battery is working good so far. Easy to replace and charged up quickly. Will see how long it lasts.

  243. Selena

    Ordered 2 of these for our electric mower. Works great now!

  244. Customer

    Exceeded my expectations

  245. sandman

    Very nice product works great for operating led lites on my tailor.

  246. Bradford Seabourn

    Great battery! I use it to power my WheelyBird Clay Target Thrower, and a charge lasts a long time.

  247. Paula Gentry

    My husband got this battery for his clay wheelie bird and has worked awesome without any issues. We will definitely buy from this seller again.

  248. elbofat

    works great!

  249. Jon G

    So far, so good. Working perfectly so far. Only had it for a little while, will update if something changes my rating.

  250. Customer

    My order arrived when it was suppose to. The battery came and was nearly fully charged. I have a 10′ Bass Buster Boat and a 36lb trolling motor. The battery powered the trolling motor fine and I used it off and on for about 3 hours, trolling fairly long distances with on problem. If the battery recharges and continues to work the way it did the first time I think it is all I could ask for.

  251. Customer

    very good, I will probably get some additional ones.

  252. Customer

    A+++

  253. RAH4590

    Delivered quick and as promised.

  254. Stewart Degner

    Have had this a long time now and it is very reliable.

  255. Al

    I bought two of these to use in my kids’ Power Wheels vehicles. The Power Wheels (a Jeep and a Mustang) were some yard sale finds – the vehicles were ok, but batteries were worn out. These Mighty Max batteries are a tight fit, but DO fit. No surprise, but to use them for this purpose, you need to do some minor, very basic wiring. If you are so inclined, I’d recommend you check YouTube for instructions. I chose these specific batteries for several reasons. The nut-and-bolt terminals allow for very secure connections to the battery. The provided dimensions told me they should fit. The sealed AGM format means they can be mounted safely in any direction. I liked that these are advertised for their long life and capacity to recover from a deep discharge. (I was concerned that my kids would run these past the point they should be stopped and recharged.) Also, these are 18 amp-hour batteries, almost double the 9.5 amp-hours for the Power Wheels factory batteries. That extra capacity means I probably won’t see any deep discharges – in long play sessions, my kids barely made a dent in the charge (as indicated by how little time my Battery Tender charger took to recharge them.) For me, these were a great deal. Two batteries for about $70, plus a few dollars for wiring connectors and fuses; they have nearly double the capacity, and they now can be quickly connected to my Battery Tender. At the time, a factory Power Wheels battery was running about $60 (and I needed TWO).Thank you, Mighty Max! So far, so good! I expect to get a nice, long service life from these. VERY happy customer.

  256. Vadim T.

    tested. worked fine. Not for a very windy weather though. I have used it for my trolling motor Motorguide 34 Lbs with inflatable boat.With trolling speed 1, will last for 4-5 hours.May be longer? did not try yet.

  257. Jingle Bells

    Have let it drain to less than 11 volts a couple times and hasn’t died yet. Been in use for a few years now.

  258. Customer

    It has done the job so far!

  259. Dan O

    Got a non-working jump box for free (I don’t remember the model, but research pointed to this as the replacement). I pulled it apart and put this battery in. It worked, and has done so through an entire Vermont winter being kept in a car outside.

  260. Moreno Graziano

    would buy again.

  261. Beth J Robb-McCarron

    Great!!

  262. Wildirishman64

    So far so good, I tracked almost three miles on a lake this weekend. Fished for six hours and used it to navigate around the lake. The battery in housed in a battery box attached to other plug ins like fish finder, usb for action cam and a voltage meter. I liked it so much that I just bought another so I can go where ever I want to and get back on time. I ran in 5th gear for almost a mile and a half at the end of my trip, no problem getting me there!!!

  263. Timothy S.

    Great buy. Works great.

  264. Customer

    Use with solar panel charging system for off-grid use. Has worked well so far.

  265. Customer

    Replacement for a dead battery on my Chicago Electric 5-in-1 portable power pack. Also added a float charger to battery to keep it charged at all times. Fits in the unit great.

  266. Customer

    I used it right out of the box for eight hours in the field with my new Champion WheelyBird Auto-Feed Trap and had no performance problems.

  267. R. Gyles

    This is an exellent battery. I received it on time. I followed the instructures and fully charged it before use on 13hp generator and it starts at the first turn of the key.

  268. H.A.H.

    I use it in a portable car battery jumper, works great.

  269. Ram

    So far so good, time will tell.

  270. Juan Rivera

    It fits exactly on my battery booster, last more time between charges. Excellent.

  271. Tim T

    Battery works well in my blue tooth ion speaker. Replaces original and I am looking for it to last longer.

  272. L. Gervais

    great product

  273. Calvin Begnaud

    It’s what I wanted, but a little too big in size for my application. That was my fault.

  274. Steven K.

    battery arrived fast n fully charged price good

  275. rick miller

    Powerful

  276. Gregory J Stadler

    works perfectly as advertised

  277. brian jaeger

    Have had it in for a month now, fits well and has the power I need. Good value and I would buy it again.

  278. ghost5849

    Works great so far. Holds a charge in my daughters battery powered jeep for a good while.

  279. Dylan Fischer

    Great battery

  280. Frank Pace

    Fit and works well as replacement battery for my Black & Decker electromate 400.

  281. Woody Woodturner

    Very pleased with this product. Well packaged. Hope it last along time.

  282. TTH

    Had a 12 AH Mighty Max Battery that is working well for me and came with great customer service, I got another one. This time the 18 AH for another backup lighting project. Both are performing well tucked in their portable, medium and mini solar generator boxes.

  283. Madalin

    Excellent Battery. Purchased it for use in a tennis ball machine (Lobster Elite II), and has been working great, it lasts about 6 hours of operation on one charge. More tennis i can handle in one session. Very happy with my purchae

  284. Paul B.

    I used it with my small trolling motor andit worked all day ,very good product.

  285. Customer

    Good

  286. Charles

    Worked great to replace battery in my Jumper box

  287. frank mazzarella

    Deep cycle for my canoe trolling motor!

  288. Magefyre

    This was a perfect fit as a replacement battery for my Cobra jumpstarter/power pack.I’ve made several purchases from Mighty Max for replacement batteries and I’ve never been disappointed. They have shipped fast and have worked great, so I keep coming back.

  289. Jesse E. Shaw

    My second one This is a stiff battery and very impressive. Read the specs for this kind of battery on the internet.

  290. C. Remillard

    Does what batteries do. Sizing was perfect. I still long for cheap lithiums, but the power supply differed in opinion.

  291. Allen T

    Received in shorter time than told. Works, and Fits great.

  292. PAW

    Purchased this battery for my large generator and it worked perfectly.

  293. Joseph D. Vail

    works well

  294. Stephen W Riddle

    I used the battery in my car jump starter that went bad it saved me 60.00 on buying new. IMO it was a great buy.

  295. TW

    Using this on my kids power wheels. Much longer ride time and cheaper. You will have to modify the factory wiring to connect the wiring and add in a fuse.Don’t skip the fuse!!! I use a 40amp fuse.

  296. Frank P

    Excellent product. I’ve used these now for a few weeks in fairly demanding applications and found them powerful and dependable.

  297. N. Smith

    A described. Battery runs my guage style head unit and 2 Kenwood speakers for hours. Haven’t really tested and timed the run time yet but happy ad of yet.

  298. anthony

    Was delivered on time. Works perfectly for my application I intended it for.

  299. Customer

    Good product for the price. My next door neighbor said I should buy these on and he would help install them. He did, my lawnmower works and I save $100 instead of having the battery replaced at a battery store.

  300. JR1

    Battery works great, I load tested it for 6 hours running a 9 portable DVD player and it had power to spare.When I started the load test the battery was fully charged at 13.1 volts, it dropped to 12.7 volts fairly fast but from 12.7v to 12.5v it slowed considerably and was at 12.5v after 6 hours of load testing.I personally wouldn’t discharge this or other similar batteries below 12.1v (for longevity).

  301. Enoc Cartagena

    It is so far a very good battery. I use them as UPS batteries only time will tell me if this is a true deep cycle battery. Until now I like the performance.

  302. pwheaton

    I had been looking for a small deep cycle battery to run by lights in my shed. I had a solar panel, and hooked it up to a controller and from the controller to the battery, and controller to an inverter. The system worked great, and I didn’t have to buy an expensive heavy deep cycle you can find at the local auto and dept. stores in my area. This is a solid, sealed battery which should last me a long time. Would by again for a use like this.

  303. jacob

    Hello, went fishing yesterday and used this battery to power a 30lbs. thrust trolling motor. I was on a colorado pontoon kickboat. It pushed me; agains very strong winds; running constantly on high power, with my fins in the water, and did for over 2 hours. I ended up over 2 miles from where I launched. This is battery is worth every penny. It was my first time using it. I had a full size marine battery with me also, and wanted to test this battery. Although it was delivered fully charged, but I put it on the charger for the night anyway. This battery is perfect for small crafts, and for on/off opperation for a day. The only thing left to find out is the life span of the battery, how many chargers it will take. EXCELLENT BATTERY!.

  304. Customer

    All good but the fit the fit was my fault.

  305. Rodd F.

    Battery worked flawlessly. Came 75% charged and I charged it up to 100%. I’ve used it numerous times to run my CPAP machine. Each time was for 3 nights and it still had over 50% charge on it. I also used it during the day to charge phones and tablets.

  306. DCP

    Using it in an MTD riding lawnmower. It has slightly larger amp hours than the original. Had it for about a month. I am impressed with the strength of how it starts. I would buy again.

  307. HK

    Bought a couple of these to rotate charging our electric fence, works great!

  308. Pappie05

    Exactly what I needed. Generator starter battery

  309. MADDOG

    THIS BATTERY TESTED VERY GOOD UPON DELIVERY, AFTER BEING CHARGED.OTHER BATTERIES I HAVE HAD FROM OTHER COMPANY’S HAVE TESTED TERRIBLE, & IN SOME INSTANCES WERE WORSE THAN THE ONES I WAS REPLACING. I DO NOT ONLY TEST FOR VOLTS, BUT ALSO HAVE A TESTER THAT TESTS INTERNAL BATTERY CAPACITY.

  310. Customer

    Exactly what I was looking for.

  311. Marvin D &34;Woody&34; Tuck

    Now this worked as described and filled my every expectation. Still working.

  312. Davidar0

    Battery has been working well.

  313. Paul Theodoropoulos

    Well built, shipped carefully, good price. What more do you need?

  314. Hemmi06

    It is hard to review a product such as a battery right after receiving them. They arrived in good shape and have taken an initial charge without issue. I will update after some use and if any issues occur.I am using the for a generator starting battery.

  315. Erich Davis

    I am using this in a small emergency box that I built. It is a quality battery that is serving my intended purpose quite well. I ran ran multiple items off this battery including low voltage led lights, fan, and a small power inverter. I charge the battery via my 100w solar panel and this combo with charge controller work well.

  316. IJN

    I used this battery as a replacement in my Stanley J5C09 500-Amp Jump Starter with Built-In Air Compressor. It is identical to the original. Replacement was easy, and the unit works very well.The item arrived on time, and is exactly as described and depicted.

  317. Bob Miller

    Unbeatable battery for the price. Serves me well as a field charging battery for my RC models.

  318. Robert E. Fritz

    Works great powering my amateur radio 2m transceiver for remote operation. It has supported 6-8 hour events so far. I put it in a small plastic box with some plastic foam to keep it upright and stable.

  319. Jeffrey Burr

    DELIEVERED AS DESCRIBED

  320. Russ

    Excellent for our use

  321. James

    Bought several of these3 for my two scoots. Can’t beat the price and the service.

  322. Todd

    Working out better than I imagined.

  323. Mark Mileham

    Installed in R1150GS. Tight fit width wise. So far so good, but turns over the big boxer with no trouble. Of course, time will tell as the parasitic load has a way of killing batteries in this bike. Will post a better review as time goes.

  324. Michael B.

    I bought this battery to set up a man portable ham HF backpack. It serves my purpose very well. At 11 pounds it was the biggest battery I thought I wanted to carry. It works both my radio and auto tuner effectively with good run time.

  325. steve locke

    No complaint’s here, bought it for the garden mower and it works great, fit right in like it should

  326. Justin

    Battery performs exactly as intended.

  327. Rachel Mackintosh

    Edit: After a year of sporadic use for camping trips and patio lighting for parties (I don’t have an outdoor outlet at my house), it’s still charging perfectly and delivering power jsut as well as it did when it was new. For another 4 day camping trip last weekend, with the same equipment as last year (listed below), it still did not drain below 12v. While not in use, I put it on a charger/tender every couple months or so. I also bought an eye-to-cigarette lighter style adapter plug for it. I’ve stopped messing with the solar charger and controller because a) for the length of trips I take and the draw I have, I’ve never had to recharge and b) the crappy charge controller I bought died anyway lol, and my wall charger has one built in. I still stick a multimeter on it when in use just to be certain, but have never had a low voltage problem. This is an absolutely IDEAL battery for my application.One thing I should note is that the iPad docking stations I use are not high draw. This is intentional. They aren’t very loud, and can be charged and then used on their own internal battery. I’ve never tried this on a more powerful stereo system, because of the increased power consumption. The ones I have are the Logitech bar style ones ( has them for about $100 each) and they really don’t use a lot of juice. If you want to rock the block with your music, you’re obviously going to drain the battery faster :)Edit: Worked for charging six iPhones and two Logitech iPod docking stations (for sale on ) through a little Bestek 300w inverter, (also on ) for a four day camping trip without recharging or dropping below 12v. We were in deep shade in the woods and my solar charger was useless. I still ran the system through a charge controller to avoid overdraining, but never got to that point. The fact that this type of battery can be laid flat without risk of leaking or damage is very handy. We had plenty of music for the whole weekend. Great investment, kept all the campers happy!This was the last component I was waiting for to set up my little solar camping gadget box ! It showed up quick, fully charged and ready to rock n roll ! Will update review after it’s been in use for a while.

  328. J. Eaton

    Very pleased with this purchase. I used in it in my electric golf cart for the first time. It performed perfectly over 18 holes on a hilly course. The pricing was competitive, especially with the free shipping.

  329. kenneth

    works great

  330. Customer

    A super great value! Looked locally but three different stores told me they would have in a few days but at over twice the price. Ordered here and got it in the same amount of time at a much better price. Thank you very much!!

  331. Randall Harris

    Nice battery. Ordred for a 13 hp Generator and it works well

  332. caremy

    Came fully charged and ready to go!

  333. gravale

    Just as needed. Very good.

  334. Customer

    Great

  335. P

    excellent

  336. John R Haynes

    great little battery, just powering alarm system, so should be months before charging.

  337. Lilly A. illiams

    It’s a good product sold at a fair price. it also arrived in a timely manner.

  338. James

    It charges well and I have used it with an inverter to power an 120 volt appliance and with clamps to a car charger for USB port charging. It seems to be a good power back up in addition to a power bank.

  339. William A. Voelkle

    I think an Excellent rating is self-explanatory.

  340. Jesus Coronel

    nice product it work 100%

  341. Steve Harper

    Works great I use it as a power supply for my CPAP when camping and recharge it for the motorcycles charging system.

  342. quantumxerox

    This are awesome for powerwheels.. We have 2 or three of these now. They will go bad over a couple years (like they all do) but the price is unbeatable

  343. Kilgore Trout

    Works great so far, I use it in a little solar generator project, I charge it with a 50 watt panel. Mostly just to charge USB stuff, but I run a small inverter to charge my MacBook. Not sure if the battery is too small or the inverter is too inefficient, but I can charge the MacBook while connected to the panel. I am by no means an engineer, just playing around with solar, and made something useful.

  344. Curtis Popke

    This battery runs good. It seems to be just as advertised. It’s clean and new and feels solid. I run ham radios with it. While the battery may deserve 5 stars I am going to punish Mighty Max for not having the model number located somewhere on the battery. It has a nice sticker on one side that says Mighty Max Battery, powered to the max, rechargeable SLA, Must be disposed of bla bla bla […] BUT nowhere does it say that I actually got a ML18-12 ! Nowhere on the battery does it even say 12volt, 18Ah. So as a customer I really don’t even know if I got the correct battery. Next time I will order direct from Mightymax, not , and request that they make sure the battery is properly labeled.

  345. Glenn Bell

    Perfect replacement for my Champion generator; and at a very good price.

  346. jkm509

    We were given a motorized wheelchair that was not working. We ordered batteries. They arrived quickly my husband placed them in the wheelchair and it started working.

  347. Ed

    I bought this battery to power a 12v power wheels I was given. It holds a strong charge for days with moderate usage. Very pleased with it.

  348. Customer

    This was cheap enough, shipped exactly as promised and had a partial charge on it that I could quickly top-off. Has worked perfectly so far in a portable compressor

  349. Frank j.

    Quick shipment. Good quality and brought my auto jimp-starter back to life.

  350. Pat OBrien

    The battery has been in service for several weeks and it appears to be working great on our electric gate opener.

  351. joseph bailey

    very good battery. good power.

  352. Douglas

    This review is for the MightMax 12v 18Ah AGM Deep Cycle Battery. The battery came protected in the box with bubble wrap. It came with 2 screws, 4 washers, 2 nut securing washers, and 2 nuts to secure ring terminals for the positive and negative terminals. Terminals are marked via color (red for positive and black for negative). It came with a 12.9v reading out of the box.My intention is to use this battery is to make a solar generator. I connected this battery to a charge controller and then solar panels to the charge controller. After some moderate use of a DC plug and USB port on the charge controller to test a DC LED light and charge my cell phone, the battery dropped down to 12.6v. The 18 watt solar panels charged the battery back up to 12.9v in a matter of minutes. I haven’t let it charge to complete maximum voltage yet but I am happy with this battery so far and look forward to putting the entire kit together in a plastic ammo can to make a portable solar generator.

    I bought this to replace the battery in my daughter’s pink barbie power wheels mustang. All I needed to do is remove the white hardware that holds the stock battery in, and it slid in snugly. If you want to do this conversion, you’ll also need to add a 30 amp fuse or breaker. You’ll also need to cut the connector off that connects to the stock battery to connect this to the car.

    Works well. Seems to be made well.

  355. Jo Wessling

    I’m using these as replacement batteries for my 3 APC ups’. They work perfectly!

  356. Orlando

    Good battery

  357. Pete Cox

  358. joshua bennett

    fast shipping and a great replacement for a small powerwheels kids toy.

  359. Gid

    came as described, perfect fit, works great.

    I have bought two of these, first one because I wasn’t sure of the quality, and then shortly there after a second. Both were to replace failed UPS batteries in an APC UPS I had gotten which is being used for a server rack in my garage. The server rack pulls a steady 4 amps at idle and these batteries handle the load for 30 minutes with no problem. Now that I think of it I should see just how long it takes to get to 90% discharged and how the batteries tolerate it.Once completed, I’ll update this review.Other than that they appear to be of high quality and arrived very quickly. The 4 stars is because they have sent me several emails now requesting this review and I’m in a bad mood. So there. 🙂 Once I do the discharge test I’ll fix the star count b/c I do think these are a great value.

    Crank my seadoo jet ski with no problem

  362. John Phillips

    The battery arrived on time. The holes in the terminals made it easier to connect a DC/AC inverter. It seems to be a high quality product.

  363. J.P.B.

    Exact replacement for generator start battery & 12 volt lighting in an out building.

  364. Clint White

    I got this as a backup power supply for my ham radio. Had a very long conversation one night with my 2 meter rig putting out 65 watts. Thought I was on my regular power supply. But when I realized I was running on this battery I stopped and put the multimeter on it and even after an hour long back and forth convo. it still had 12.8 volts. Love it!

  365. jimsan10

    Battery was delivered quickly, in good condition and fully charged.I used it in an emergency car starter pack that I keep in my cars trunk. The old battery that was replaced would no longer hold a charge. This new battery was a perfect fit.

  366. C. Duke

    My portable battery booster finally lost its recharge after 6 years. I was going to get a new one but decided to take it apart to see what kind of battery was in it. This was the duplicate so instead of $90 or so I got this and my booster pack is back in business just like new again.

  367. A. Alcala

    Came with new bolt and washer too! Fit fine inside portable air compressor and battery booster. Was exactly as described.

  368. Paul S. Janucevic

    Great product, Great price!

  369. bobtampa

    Great value.

  370. Douglas L. Hatch

    Replaced battery in auto jump starter that died after two years. New battery fit into unit perfectly. Increased capacity over old battery. Much cheaper than buying a whole new unit. Battery was shipped quickly and arrived before I expected it.

  371. Rob Stuart Jr

    Worked as expected for my power wheels Kawasaki brute force quad. Fit right under the seat perfectly. Came charged and ready go! Great product!!

  372. ed day

    Does a great job. Holds a charge just as it should as a new battery. Since they were much les expensive than the OEM product, this makes them a real value purchase.

  373. Rog

    On tim, fits, and it is as described.

  374. Thaddeus

    Excellent product. Put my 4 in 1 Jump/Start back to work. Shipping speed excellent.

  375. r Custome

    I ordered on Nov 19, 2015. It arrived a few days later. I noticed a small amount of oily staff on surface the battery.I used it the replace similar old battery used on my chipper. I used twice. On Dec 15, 2015, I found the new battery is totally dead. I tried to charge it, but did not work. I measure the voltage, it was zero. Is it a dead battery or what?What can you do with itML18-12 – 12V 18AH CB19-12 SLA AGM…?

  376. Gary F.

    Excellent replacement battery for my jumper pack; old one had only 45CCA capacity; these have over 200CCA; expect to replace them every 3 years or so.

  377. Jim

    Perfect fit.

  378. John Maria

    Fit in my Black and Decker booster. Charged quickly. Arrived in two days in excellent condition.

  379. Mallard

    Battery has worked perfectly since its arrival. Use it to power small 12v pump to move water from rain barrels to water a garden. Use a solar panel to charge it. Is working very well. Very satisfied.

  380. Customer

    Perfect fit into the power-pac that I liked.

  381. Eric

    Works like a charm.Great price too.

  382. Aristeo Arredondo

    Have yet to full exhaust the battery. It does fit perfect in a metal lunch box that I used for a stereo system on a beach cruiser. It was shipped and delivered as promised.

  383. Walter

    This battery is bigger than my usual 12-Ah, but I wanted this big boy to assure the reliability of my floodlights, spotlights and intrusion alarms, out here on our ranch. He’s doing a good job, and he is about to get some serious back-up, as I am ordering two more of these big boys.

  384. RickVL

    What does one say about a battery? It does what it is supposed to. Needed charging when installed but no issues. Would recommend, and will buy again as I have other equipment using the same type of battery.

  385. tolly

    This a good battery. worked fine on a lawn tractor of mine.

  386. Michael B.

    Have had this installed in my Champion generator for a couple of months. So far it turns over every time. Hopefully it will keep it’s charge over time. I will update later.

  387. Customer

    Bat came fully charged and holds v good. Works well with my project. Delivery came as projected.After several months with this battery I had ordered three and two are holding their charge while the first battery is draining to fast while just hooked to a solar charger it’s ok. So two out of three not bad. I do like the price od the unit, and probably order another one.

  388. Customer

    very good product fits perfectly shipped on time thank you

  389. D J

    Does the job now but it’s too early to tell how long it will last.

  390. S. Ellis

    Good quality battery. Price point is right.

  391. Lin

    Battery works great

  392. LittleBlueJeanne

    I can’t review it till we get our solar up and running, so giving it 4 stars.

  393. Trevor

    This was purchased for my generator,it seems to have more power than the original Battery.Lets hope it last longer.

  394. racecar

    works great, i used this in a battery jump box and it exactly replaced the original.

  395. P. GLASSER

    This has kept my strip of LED lights running for quite a few days without needing to be recharged. Nice for camping lights when you don’t want to hear a generator.

  396. Christina Maule

    Great battery. Perfect fit. Super fast shipping. Very pleased with this purchase. Will buy from this company again.

  397. RalPhstEr12V

    Measurements and weight are correct. Great battery with a high amperage output for its size.

  398. jos

    Works fine and is perfect for the application for which I obtained it.

  399. Pilot67

    Great battery. Delivered on time and without damage.

  400. George R. Roth, Jr.

    Quality battery; prompt delivery.

  401. Corny Gossett

    Last year’s purchase

  402. Maurice Boley

    Works good for power wheels.

  403. Kevin Kiely

    Great price and prompt shipping

  404. Joey McNeill

    I’m really happy with it so far.

  405. Carolyn C.

    As expected , and right on time.

  406. Clint

    Very good for the price! Seemed to be charged when I received it. With that being said, I did leave it on a battery maintainer overnight just to be sure. It’s powering an amplifier in a radio cooler. 400 watts, and 4 speakers. Went to the river this past weekend, 6 hour float…plus about two hours of hanging out…and the battery never skipped a beat. Went home, and it wasn’t even discharged as much as I thought it might.Great purchase and definitely recommended!

  407. Pjw.

    Great price came early. Would buy again

  408. Brian K.

    Everything worked great.

  409. Bryan

    Great deal! Came juiced up ready to go

  410. Ernest Trevino

    Excellent purchase the right product at an excellent price plus timely delivery. Will gladly buy from this vendor again.

  411. GPD4

    They arrived on time, they fit the cases, and they work.

  412. Kippy

    Works as expected. Replaced the one in my Stanley 500 amp jump starter which otherwise would have been toast.

  413. Jerrold A. Taylor

    After analyzing measurements, terminal polarity locations etc., I ordered this battery to replace my dead jumpstart box battery. A perfect fit with a nearly full charge when received. I am totally satisfied with the transaction and the battery.

  414. W. Barton

    The battery I received works fine. This is the kind of battery that is used in things such as wheel chairs.

  415. JESSE ONEY

    Excellent battery ,,

  416. D. W. Mabe

    quick delivery. battery was as advertised.

  417. Scrambler

    Needed a replacement 12v, 18ah battery for a Briggs & Stratton generator starter. This one met the requirements, fit the battery holder compartment precisely, with only a minor tweak for the cable connections. Battery arrived almost fully charged (13.54 volts), more than enough to start the generator on first push of the start button. Excellent price, which included shipping.

  418. guido trivilin

    Using this to replace a full size marine battery in a boat of our own design. Powering a small trolling motor as an emergency device. At 14 lbs. vs. 50 lbs. it’s a blessing for loading etc.in the boat. Very powerful so far comparatively speaking. Minimal drain after 30 minutes of downstream cruising. Will update this posting as I will be using it and an inverter to run our icemaker.

  419. Customer

    I was looking for a expendable 15-24 ah battery that would last me 2-3 years on my kayak to run my gps, fish finder and navigation lights for 8+ hours. Battery arrived in the time stated and was in good condition even though I initially had doubts about packaging. Placed battery on charger in agm mode. It was at 92%charge so started to charge. Came back 15 minutes later and the sealing plate had blown off and 5 of the 6 cell caps had blown off (one cell cap was found 15+ feet away) one of the caps was not found. In this condition the battery was of no use to me as it no longrer a sealed battery. Contacted customer support and Mighty Max customer support. Mighty Max was very easy to work with and after I had sent them pictures of the battery condition Mighty Max sent a replacement battery. I am very pleased with the new battery and Mighty Max. I have raised this rating from 1 star to 4 stars because of Mighy Max’s great customer service.

  420. D Eaker

    As advertised

  421. Wesley Peake

    super duper battery.

  422. Edward J. Saurazas

    Best AGM battery for the money. I use them to start my waverunners. You can let it go dead many times and it will still take a charge.

  423. George Collins

    Very good little pricey

  424. Gretchen CLS

    Works great! Came almost fully charged. Use it to run the drive for a telescope when away from a power source.

  425. Chad Moore

    Very happy with the battery so far. Wouldn’t hesitate to buy another.

  426. jcm

    I’ve used the battery for a month to run an 11.5 Briggs & Stratton engine for a riding lawnmower. It holds a charge and starts the engine every time. It is smaller than most 12 volt batteries for these engines but definitely has enough power.

  427. Eric C

    Batteries performed as advertised so far. Let’s see if it lasts at least a year unlike Batteries Plus which costs so much more and they last just about a year. The original batteries for the Jump Boxes lasted at least 2 1/2 years or more.. I would say an excellent buy..

  428. Tom S

    Battery is an exact replacement for my original equipment battery and was fully charged. The delivery was quick and the packaging was appropriate for the product. Additionally, the cost was less than half of the OEM battery.

  429. Customer

    Excellent upgrade for my son’s 6v Power Wheels.

  430. Chuckeroo

    Great little AGM 18 amp hour battery. Works for my powersport applications.

  431. Maria T. Marth

    Great battery. Im using it with a power inverter and it works perfectly. Now when I go camping I can have power at my campsite and make Margaritas!!! Yay!

  432. JY

    great performance

  433. Gregory H. Becker

    These are for my wife’s mobility cart. Her cart now has the get up and go she wanted.

  434. Mike B

    I used this to replace two 8ah batteries wired in parallel for my mighty mule 350 gate opener, so far it works great and appears much cleaner in my application.

  435. Travis Ritz

    Battery worked great, the customer service is outstanding, had a small issue and the resolved and were very professional…will definitely recommend this product and will be purchasing more in future!!!!

  436. alex sledzik

    This is a grate battery for the price! I ordered two of these batteries and they arrived in grate condition but were a bit sticky from the tape used for the terminals. The only thing I see that could be concerning would be the thickness of the terminals seeing how they are about two thirds the size of the batteries I originally had but other than that these are the best batteries I have

  437. Roger Ramey

    great battery ,would buy again

  438. Mike J

    Arrived at 13.1V, Which is full enough for me. I use a battery tender jr to get to full charge. Battery is quite nice and works well.After a priority shipping issue, the company did a great job responding to the concern and made things right as can be!Boxed well and arrived safe…even after a week with USPS!

  439. williewyotech

    Great for the price. Now my jumper is again ready to start a dead battery car.

Ordered from Amazon. Received - fits great !
Battery will not hold a charge, was not fully charged when I recieved it. did a 1 amp charge until meter said full and it would even turn my mower over to start it..
I have always been satisfied with Mighty Max batteries. This battery will be used on my home stand-by generator.
Awesome price arrived fully charged and ready to use
Ordered battery from Home Depot (online). Eager to change out old battery for the new battery!
I ordered this battery for a remote trapping device. It arrived in a short time like 3-5 days. I was out of town when it arrived. I’m using it tonight to trap feral cats to take to a spay neuter clinic.. I’m hoping this battery lasts me for a long time as it’s a vital piece of my trapping equipment.
Packaged very well, excellent price and fit perfectly! I was able to restore 2 Razor Scooters for a lot less than if I had gotten batteries somewhere else.
Great Battery Great Warranty
Great deal on a good battery!
this is my third Mighty Max Battery. I have two others operating in my ATVs. great product, great price point
