    Good product

    I almost threw out my old jump pack and then thought just for crap and giggles I’d see if they had a replacement battery. They didn’t but the one they had was even better and it was the same size. I had also lost the charger but have been using a Black n Decker that I also bought on . I found the old charger and was shocked to see it barely put out 12 volts. The Black n Decker charger put out 14+ volts just like an alternator. Very happy with both purchases.

  4. JB

    Battery arrived safely packed and fully charged. It’s outside dimensions were the same as the one it replaced. The terminals were located slightly more inboard than those on the battery it replaced, but overall it was easy to install. Good value for the money.

    Seems to be working so far. Not sure about how long it will last since I don’t actually use it all that much. I bought it for a trap thrower and it worked fine for the first 100 clays. I haven’t shot any since. I plan on buying another for my second trap thrower that I will purchase in the future.

    worked great

  10. DJ Escalade

    Great battery to replace those junk batteries in your lawn mower that die every year or your ATV when adding lights and winch and other accessories

  11. Customer

    Batteries work great fits exactly as expected holds a charge for a long time would definitely buy again

  12. Pinky

    I have an old jump box that includes an air pump, work light, etc that I rather like but the battery was dead. So I cracked it open to see what battery it had to get a new one. The original was 18AH but this one is the same size and 22AH. Price was about half what I’d have to spend for an equivalent new jump box so it’s a 360 win. One of our vehicles has a problem with battery drain while it’s sitting so it’s been used quite a bit and I’m more than happy with the performance.

  13. Roger

    It is a battery. It works.

  14. Steven Luecke

    Great product

  15. thisisdick

    So far so good.

  16. B. Snook

    Totally solved low power issues on a mobility scooter, hold a charge.

  17. Mike H

    Excellent Product Great Price Fast Shipping Best deal on the internet

  18. John Lloyd

    This is the 2nd one of these I purchased from . No problems with the first one, but the 2nd one arrived in about a 70% discharged state, which is bad for the health and longevity of the battery. It took about 12 hours using a 1.3 amp charger to bring it up to full charge. It had probably sat on the shelf for quite a while, or else it has a higher than normal self-discharge rate. Seller should take the time and effort to maintain and ship these fully charged.

  19. TPeterson

    Second time around getting these for my Pride Mobility Scooter. Perfect fit, nice reserve power. Great bargain!

  20. russell frederick

    Small upgrade for my worn out jump pack and alot cheaper than new jump box..

  21. David B.

    This perfectly fit my AST alarm box and replaced the original battery. Is working flawlessly and exactly the same or better than the original.

  22. Scott S.

    Excellent upgrade for my existing battery.

    worked great

  26. CYRUSRONNIERAYJONES

    GREAT BATTERY FROM DAY ONE….THANKS…..

  27. JohnDBaptist

    Fits perfectly.More power than previous battery.When the time comes, I’ll reorder this again.

  28. brent

    The first think I like about this battery is that it came in one piece. So often when something like this is shipped it gets smashed by the delivery people. Although this was packed ok, it could have been damaged if it had been dropped or thrown. Fortunately the usps actually did not drop or throw it. So it came in one piece and did not crack or leak. I have put it into a portable jump started and it is working well so far. Two or three years from now I will know if it was really a good battery.

  29. Chris

    I used this to replace a battery from a car jump starter. I am pleased that this battery has a higher amp hour specification but is able to fit perfectly where the old battery resided in the housing. It has so far met my expectations and I am comfortable recommending this battery.

  30. j mize

    We love it!!!

  31. John W

    This battery was exactly as advertised. I was looking for a battery that would work well in my generator in the cold Northeast winters. Have not yet gone through my first winter but fully expect that I won’t be disappointed. Delivery was ahead of schedule. Happy with my purchase.

  32. Alec Barry

    GREAT BATTERIES AND GREAT PRICE…..

  33. Doug

    Works with my UPS.

  34. Eric N.

    this battery runs 12v dc accessories in my boat. clean power for electronics depth finders etc

  35. Customer

    I installed it in my battery jumper and it fits perfectly. Time will tell how it hold up.

  36. walter a, balawender

    Great price, fully charged batteries when delivered.

  37. Bartley J Ives

    Battery worked just fine on my generator. Had it about a month so far and still able to turn over easily. Time will tell if it will last through until next summer.

  38. Karen M. Nelson

    It was exactly what I wanted and worked very good for my needs

  39. W. M. Greene

    Light weight, portable. good power. Use it for my deep drop electric reel. Lasts all day.

  40. tim grass

    Great purchase! I really like the price and quality.

  41. Customer

    I bought 2 of these to power a custom 24v power wheels and am very happy with the purchase. The kids run the PW daily in the grass for several hours and I charge it every few days over night. To get the same battery and AH from batteries llus or similar, you would pay easily double.

  42. Todd

    Perfect fit for a jump starter, more powerful than the original. Cheaper than replacing the unit.

  43. Daryl S.

    Did what I wanted.

  44. David A. Elston

    replaced original exactly

  45. arte mccollough

    quick shipping, fit perfectly

  46. Customer

  47. M. Schwarzenberg

    Very good, fully charged when it arrived.

  48. Diane

    Works Great!

  49. jim lavergne

    perfect fit for my generator.

  50. Josh Winters

    Saved a bunch of money on a new 12v jump box (about 66% off the cost of a full replacement box) with a simple battery.

  51. Adam

    Good value, I bought two of these to build my own solar power box and they hold a great charge, can last for days charging 12v supplies and gadgets. Would purchase more if i needed to

  52. Customer

    Fantastic upgrade for my booster/jumper pack from 18ah to 22ah; which is about 22% more juice for starting. Jumper pack works better now than it did when it was new, and it had been going downhill for about a year until it finally wouldn’t hold a charge any more.

  53. Thomas H. Milidantri, Sr.

    Excellent replacement

  54. Laz

    Supposed to be a 12V 22AH battery. There are no marking anywhere on the battery indicating that it is a 22AH battery. It should be clearly marked as described and as in the photo on the website, but it is not.

  55. Paul Honn

    worked great in my DR field and brush mower, started better the than the first battery. great buy

  56. Broken Like Me

    Great deal on a great battery! I used it to replace an older 18AH battery in my portable power station. Gives me more jump start power and more compressor time. Highly recommended replacement for portable jump starter with same series/size battery.

  57. Sergio Torres

    So far i have been using this upgrated battery on a matco tools jumper i have had for years now sitting in my garage. It has been working excellent and last quite a bit with out having to recharge. I have to say its a good buy.

  58. ronnie ramirez

    awesome battery thank you ronnie

  59. YellowJacket

    Good

  60. Poncho Train Sailor

    Perfect replacement for a Jump Starter battery that I carry on my boat.. Battery is exact replacement for the battery in my old Everstart Maxx jumpstarter.. Replacing a Prostar 6PS0220, 12V battery, 22 Ampere Hours

  61. Jim H.

    Batteries delivered on time (bought two of them) Used them in an electric lawnmower. Batteries seemed a little lighter in weight than the 20amp lead acid gel cells they replaced but these are running the lawnmower just fine and on full charge perform just as well, if not better, than the batteries they replaced. Time will tell if I get the same three seasons of high current work that the old cells provided…

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
