    I put these batteries in a Black and Decker 36V Lawn Mower battery I bought in 2013. All that was needed was new batteries to restore it to power that it had when new. The install was fairly easy there are youtube videos that explain it. I needed to cut out a small piece off the case to fit in one of the batteries flush. It showed how easy that is in one of the youtube videos for B&D 36V battery replace. This saved me about $400 that a new self-propelled lawnmower would have cost. If I can get 2 or 3 years more out of this mower it will be well worth it. When you install the new batteries be careful with the gray piece that connects into the gray piece on the lawnmower. There is a very small bar that secures the gray piece to the case. You want to keep all that intact. so it snaps into the mower body.

  7. George Higdon

    The media could not be loaded. Great batteries. What I like they charge every time and they work . They are dependable. Unlike lithium

  8. Cecilia Radwan

    just replaced this battery and it works like new. easy to replace and now the mobility scooter is like new.

  9. mike32927

    This is my second order of three of these batteries. The last three ran for about 2 years, which is what you can expect for an electric lawn mower. Make sure you fully charge them before using them the first time, and make sure all the leads in your electrical device are clean from corrosion.

  10. Darline

    Fits like a glove. Super easy to install. I’ve had it for about two months now and still holds a charge.

  11. Mark T

    These batteries are great for power wheels and other ride-on vehicles. I have one Mighty Max battery that’s been going strong for 3 summers now- still holds a charge as good as the new set I just bought. I tried Chrome batteries and they lasted one summer. Won’t make that mistake again.

  12. Shopper

    Brought my Goal Zero Explorer 150 unit back from the dead. 10 minute replacement process.

  13. Michael M.

    Put this in the 3 year olds barbie jeep, works fantastic. Wired in a 12v socket outlet on the side like a tesla plug and put the male end on a 12v battery tender for easy charging. Kid loves the extra run time and easy to plug in without worrying about polarity. She also runs a radio and Bluetooth speaker wired into the battery and it handles everything as expected.

  14. lesha58

    Used this as a replacement starter battery on a 5500 watt briggs and stratton generator with electric start. Has been working great and no issues for the few months it’s been on it.

  15. Rommel Lamayo

    A great backup battery for my ham radio and other emergency equipment. Sometimes use it with a small inverter to power patio lights in the backyard. Charges USB devices, as well. My last Mighty Max battery lasted 3 years before it gave up to the Arizona summer heat in the garage. Also used a Coleman solar panel to charge it while camping or helping our local PD with traffic management.

  16. Gerald Nierman

    Got the scooter going again.

  17. leroysmith

    Use it in a 3-wheel scooter for a car show

  18. Txrumbles

    Got this for my kids electric car and works great. Higher amps held hold up longer and faster.

  19. Kendra Oxendale

    You looking for some power? You looking to occupy your kids for days in end because this baby provides so much run time for their power wheel? You looking to have your kids fight over what battery they use in the power wheel because this battery works so well? Well this is the battery for you. Look nice. Feels nice. Smells nice. This thing rocks. Batteries!!!! I love batteries!!!!!

  20. Michael M.

    Received today damaged. Tried to replace, but this item is non returnable.

  21. Michael P.

    works great

  22. itjstagame

    I chose this because it fit the same exact footprint as my original ride on toys battery. However, mine was originally 12ah and the company only offers a 10ah for $100! This was 15ah for a fraction of the cost. I was able to take the connector and handle/case off my old battery and put it on this one. Installed product is identical to original but 15ah.

  23. Jmeihn

    So far it out preforms the brand it replaced.

  24. JC

    Lasts way longer than original battery!

  25. charles E

    These are a nice upgrade from the 12 ah batteries. I don’t know, if you’ll notice a huge difference, but the reliability is there. Just have some basic wiring skills, and yellow connectors ahead of time.

  26. lior nobel

    Just got it so far works great

  27. Stacey

    I bought this battery for my grandsons power wheel. It easily stays charged with a battery tender

  28. Delawhere23

    Battery is a perfect replacement for the Kidtrax police car ride on toy. Just take the plastic case of the old battery. Disconnect the wires and then install on this new battery. Batteries are the same size physically but this one holds more charge.

  29. Jameson

    Used it on a power wheel John Deere worked well today.

  30. Jared Wayne Clark

    Bought this battery to replace a small mAH battery in a powerwheel. It was easy to swap out and fit within the storage compartment of my Jeep powerwheel. It has held a charge well and seems to last a really long time. Easy swap out and great replacement option.

  31. Mary Ann Caruso

    Batteries worked great!

  32. Michael T Lieberman

    Installed and started the generator! Came charged.

  33. jason holliday

    Used this as replacement of my daughters Bens power wheel battery. The original battery was 12v 12ah so the 15ah gives it a little longer run life. Also its the same dimensions so the original battery casing and plugs swapped right over. You cant tell a difference. This was a true plug and play replacement.

  34. Robert D.

    I used these to upgrade my kids Power Wheels Baja Extreme to a 24v so I bought two. Even using one before the upgrade, the Batteries seem to outperform the stock battery that came with it. I have purchased these in the past for Power Wheels upgrades and have always been happy with the product. The 15ah is the largest size you can buy to where the battery will still fit in the compartment. The 18ah battery is too big. Upon receiving, I was pleasantly surprised that the batteries were pretty much charged and only required a mere top off. They have been sitting now for over two months due to the winter weather and I just checked to see if they discharged any and they have not! Still fully charged.

    Exactly as states, easy to install as long as you watch a video

  37. tacoma 2gen

    Added 2 of these batteries to my son’s Razor MX350-24v bike. They were wider side by side but made them fit on same plate old batteries were on. My son now rides his electric bike a whole lot longer and same battery charger works to charge it. Also changed throttle switch. Nothing else. These batteries are worth it. Haven’t had any problems so far. Have had them only for about a week and used everyday since arrived with no issues. They came packaged good. Old batteries were 2-12v 7ah. These are well over that.

  38. Stanley reid

    Works great but was larger than the original battery

  39. DKSharky

    Replaced 3 battery in Razor dirtbike. Worked well and easy to install.

    I was concerned about the many reviews that said this batter will not fit the GoalZero Explorer 150 battery pack but went ahead and ordered it anyway. All I can say about those that say it doesn’t fit, is that they either got a different battery or really didn’t try very hard to insert the battery in the case. I’ll admit that it first appears that the battery might not fit but all you need to do to get it in place is to gently spread the two parts of the plastic case a part just a bit and then apply a couple of slaps with your hand and it will slide right in. I’m guessing that GoalZero designed the case to fit tightly so that the battery does not move around when it is being transported, etc. I just received this and haven’t had a chance to use it but will be going on an extended camping trip over the next few weeks and will update the performance after I return.

  42. Brad Weeks

    Fit and works great

  43. John R. Cook

    I was a skeptical about the quality for time of use for this battery but I am very satisfied about having a 20 to 30 minute long (on average) driving session with my kids going up and down a 15 foot long steep hill and flat yard. I had to modify the vehicle’s wire harness using a old battery connector to change the connection to a typical spade style for this battery. The modification was expected to be done and not a problem to enable the use of this increased capacity battery. I will buy another battery in the future for other projects and to have a extra battery for the truck. The PEG PEREGO factory style battery was 12AH and cost more than double of this 15AH battery.

    Fit my grandsons 4×4 power wheels perfect, last alot longer than the original

  46. Arthur

    I bought this battery for Wagan 2485 Power Dome NX (car jump starter and air compressor) as it is the same size battery and has same specs. The only problem was the battery connectors, the original battery had a RING terminal and this battery has a TAB terminal. Since it was hard to find a battery for my power dome, I just soldered some connector adapters I had handy and made it work.Other than that, the battery looks good quality and the rest I will find out in time.

  47. Jason Palma

    Only hold 80% charge

  48. James Marshall

    They did great.

  49. Anthony Buxton

    Purchased to replace bad 12ah battery for a pegperego 12v ride on. Popped old batter out of case and onto this new battery. Noticed battery stays cool while charging and runs much longer and stronger that the original. Great purchase!

  50. J. Nagel

    Great value. Arrived fast. Great replacement for toddler’s power wheel.

  51. Nguyengineer

    Came well packaged and fully charged. Using it for a fish finder on a Jon boat. Fits perfectly into a Plano ammo box if you wanted to make a battery box.

    I chose these individual batteries instead of a battery module which cost much more than the individual batters.

  60. Ryan

    Purchased for a Razor MX650 electric dirt bike. Works very well, and fit nicely in place of older 12mah batteries. The main trouble was that the original batteries were soldered into the wiring harness, so I had to cut the wires to remove the old batteries. I then had to install crimp connectors on the end of the wires, which would connect to the new batteries. It would be nice if a wiring harness was included with the package, which would have eliminated some or all of this hassle.

  61. JOHN HUSKINS

    I do like it when you get just what you expect. Battery is good quality and works great in the boys power wheels ride on. Is exactly as described.

  62. R. Blanch

    When it comes to batteries only time and work history will tell the truth. It came in a good package fully charged. I have yet to try to recharge it.

  63. DELIA gonzalez

    This battery last 2 miles more than the 9AH. I’m very happy with this batteries.

  64. the Joes

    Great replacement battery for the price. Easy to install and well worth buying on-line, v/s at a local battery store. It is 1/2 the price..

  65. Dean Fife

    Not much to say, they came 95% charged and I used them in my SMART-UPS 1000 with no issues. I won’t have any longevity data for a while. But they look well made with no issues.

  66. M. L. Wilkinson

    Have not yet installed in my little Goal Zero to replace the old bad battery but will do shortly.

  67. Dan K.

    great battery holds voltage well. I used it for back up power supply for a CPAP machine it can power my CPAP for three nights without recharging Love it

    Awesome. Keeps my sons peg pereggo tractor going all day long

  70. Steve

    Works well. Great fit into sons Gator. Better than the originals. Take the blue case off and put this in so the wire harness is on the battery. 2 new better batteries cheaper than 1 peg battery.

  71. ERicincal

    good battery but slightly larger than the battery that it replaced. If size is of a concern to you, be mindful of this fact. Had to tap in in with a rubber mallet. Worried when it comes time to remove it.

    As described, has worked well through the first few charge cycles.

  77. Jesse E.

    Perfect replacement for any overpriced powerwheel battery!

  78. BookBuilder

    Excellent battery. They fit perfectly as a replacement for my original batteries in my Lynx L-3 mobility scooter. They significantly improved performance over the older batteries; I have a run I make nearly every day which is about 1/.2 mile long and most of it up a fairly steep (for a mobility scooter) grade. Even when new the original batteries tended to deplete some by the end of this run. Not the Mighty Max’s. I suspect the issue here is discharge rate and the Mighty Max does a great job there. I would recommend most strongly.

  79. J. Kime

    Perfect replacement battery for my dads scooter.

  80. Richard D Mack

    I bought two of these batteries for a mobility chair and upped up the amperage from 12 amp to 15 amp for longer range. These batteries are great! Well built and they fitted in the same case. Good price and will buy from them again. By the way, fast delivery also!

    Perfect replacement for the grandson’s 4 wheeler, I just wish everything on the 4 wheeler was as easy to replace as the battery was!!

  87. RLS43

    I recemend this battery, It gave my mobility scooter a new life by being able to run longer on a charge than the origalal battery. I will use your batteries again. I hope this helps someone to use THE MIGHTYMAX BATTERY.

  88. Larry Rigney

    Although they came dead, they charged completely in about 8 hours. So far, so good.

  89. Christopher Smith

    Excellent replacement batteries for Lashout electric bike. Increasing to 15AH has both increased power, it has increased mileage with no harm to the controller. To extend battery life, wire in a cheap amp meter and keep your demand above 21.9.

Mighty max brings the battery backup back.
Arrived well packed in unopened sturdy box. Was replacement for identical Mighty Max battery I ordered 2 years ago. Taking 1 star off because didn’t include the needed terminal clips - was able to use the old battery’s clips
Same model fits in each of our four wheelers great product
Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.
Direct replacement for generac portable electric start generator. Works great.
Received really quick. Boxed well and fit great. Worked like a charm! I would definitely recommend this battery.
As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
Needed a replacement battery and the manufacturer wanted $50 whereas you only required $20. Made it worth it!
satisfy with price and easy installation.
Arrived in great condition comes with the bolts to attach the wire over all very satisfied
