  1. xer

    It works well to power our emergency generator. It arrived quickly and was easy to install.

  2. Northeast WI

    Package arrived double boxed from factory with padding inside both boxes. Nice touch. Came charged up and have used it now a few weeks. Holds a charge long. Used in a camper with stereo and TV with computer going for quite a few hours after a few days and still shows 80%. Would recommend.

  3. Michael

    So I’ve hadthis s battery for about 7 months it was decent in the beginning for my 10 ft water tender. Though it seemed like it never really fully charges, as time went by the battery life while trolling got worse and worse. Now I can’t even get around the lake. This battery is compact so I see what anglers want to use it but for but what I’m now getting out of it I should have just bought a marine battery. So ya get what ya pay for. I load tested and it’s says good but the charge doesn’t last long at all. Spend the money and just get a deep cell.

  4. Tiger

    great trolling battery

  5. Vickie F.

    It was easy to install and great price

  6. Mr. Lee C. Boyer

    I bought the wrong size. The staff was excellent and sent me a return slips. Highly recommend mighty max batteries.

  7. edwardclaessen

    Battery was used to power a power chair. Can’t rate the longevity of the battery at this time. Adapting the unit to the chair could have been easier, however it was manageable.

  8. Not a paid review

    Used with my 35# trolling motor for my kayak. I can go about 6-8 hours with this and still have 25-50% charge left over. Only downside is that it weighs about 35 lbs.

  9. Glenn H.

    Quality seems good. Safely packaged. Too early to tell longevity, I do have another of this brand still performing on a solar system after four years.

  10. 3MC

    I honestly wasn’t too sure about this battery, I didn’t like the terminals when it came in, they are set back and you can’t use wing nuts for your connection. I purchased a quick disconnect and bolted it on so I didn’t need to worry about wing nuts. Performance wise this battery is awesome, I’ve done several 6-7hr tournaments running the motor on my kayak and it’s never been low on power once. I’ve even used it to troll for hybrids for hours and it never let me down. I use a NOCO10 charger to make sure it’s topped off every time I use it. I plan on buying another for my John boat. 5stars!

  11. William

    I would buy it again

  12. Web Customer

    Bought batteries for electric wheelchair. Everything was exactly what I expected. Received order very quickly.

  13. oldman

    Been installed in my generator for only a week but so far works very well.

  14. Theodore D Washington

    The battery is a very good battery. I recommend getting two batteries. One for the trolling motor and one for the boat power panel.

  15. Web Customer

    The battery is great unfortunately you may get a bent post due to shipping. Also the nuts and bolts that they send to attach to the post are of such low quality they have a tendency to cross thread and bind then you can never get them off. I ended up having to drill mine off and go buy high quality nuts and bolts. If it wasn’t for that I would have given five stars..

  16. Robert Casagrande

    Purchased for my 40 pound thrust trolling motor. Only been out once but fished for 5 hours moving around quite a bit and crossed the lake a couple times (3/4 mile) and still had plenty of juice left. Used about 1/2 of its charge. We used it on lower speeds most of the day.

  17. Parallax

    I purchased 4 of these batteries to connect in series for a total of 48V. At only 36 lbs, these batteries are easy to carry around without hurting myself. Sealed construction means I don’t have to worry about these batteries leaking on the carpet of the floor. There are plenty of positive online reviews about these batteries dating back to several years, so they seem to withstand the test of time pretty well.

  18. jake

    Works great. Used it on a kayak to power a trolling motor.

    Good product for a good price

  21. Rusty Gate

    Batteries came quickly and are installed the mobility scooter and working with no issues.

  23. roger slone

    Installed quickly and took a charge.. Curious as to why the +/- were switched on the battery. Fortunately the connection leads were long enough.

  24. Noeum S.

    Great

  25. Jim Gordon

    I hope this lasts longer, the weight compared to the 35AH of mine that died is hefty, may be thicker plates. They call it AGM equivalent SLA. Arrived in good condition with 13.1 volt charge. I want a stand by source for Florida power outages – fans and CPAP use. The price per amp hour is not especially great but this won’t break your back moving it.

  26. Kiomars s.

    Definitely worth every penny

  27. Elvis

    Nice

  28. David

    I am using this battery for a 35 lb trolling motor on a sea ghost kayak. Works awesome use it usually nonstop for 6 hrs thru all speeds and never dies on me. Lay it down sideways in the front of kayak does not leak

  29. LisaB

    The wheelchair I am having to buy replacement batteries for, the batteries got fried when plugged in all the time and got hit during an electrical storm when we weren’t home. The chair was made for a 400lb person and I am 200, it was way too big. Anyway, the new Jazzy wheelchair I purchased states to not plug it in continually, only over night before you use it if necessary. When I looked at my old wheelchair it said the same thing just more convolutedly. Just FYI for wheelchair battery users!

  30. Allan Turner

    Hover around electric chair

  31. Linda G.

    Purchased for someone in nursing home do not have first hand knowledge from useing. As I previously responded they should be packed better for shipping they came seperated one well packed the other not as good. Friend in nursing home responded batteries wrx great

  32. Robert Saegert

    Electric gate. Don’t know the longevity or life yet.

  33. Stephen

  37. J. Keller

  38. Rachel Norabuena

    Works great for my camper. Received first battery with terminals flattened but easily got replacement sent promptly from .

  39. Justin Ozelek

    I added this to my boat as a 2nd battery. I’ve had it playing music on the lake with my boat radio that has a 400watt amp and 6 speakers, it hasn’t quit yet!

  40. Turkey Hunter

    Not a bad battery but comparable batteries can be found at a much better price. I would not purchase again based one the value for money. Found better prices in stores. It does run my trolling motor pretty well though.

  42. Jesse Neddenriep

    Ordered two of these 12V 55AH batteries and both of them arrived with the top posts smashed in. They need to figure out a way to package these better! No idea if batteries are any good yet as the project remains on hold until we can get replacements.

  43. George W Keller

    Vary good and durable batteries. Can sit for days not on charger and not even lose 1/10 of a volt!! I highly recommend them…

  44. Web Customer

    I would recommend this product to anyone it is what I expected and more.

  45. beachnut443

    We use this battery with a 55lb thrust EnduraMax 5 speed Minn Kota motor attached to a canoe and get about 1.5 – 2 hours of battery life on constant use. We run the motor on 4 and 5 most of the time and are very pleased with the battery life.

  46. Yogi1Bear

    Great Price I went to the scooter store to get 2 of these for my scooter and it was double in price so thanks to I found these and the fix perfect and easy to install, Shipping was fast great job.

  47. Frans Andrea

    Great battery for the price. Using it as my solar battery on my camper

  48. Web Customer

    Very 0good battery. Eveerything you said about the battery is true.

  49. krisjanis gale

    purchased for use on a camping trip as an on-the-spot power source for charging cell phones, powering small audio/video devices, etc. it worked perfectly and lasted much longer than i expected! mighty max packaged the battery well, it shipped fast and in perfect condition. all around, great!

  50. Satchmo

    The batteries work well giving many hours of mobility between charges. The terminals are not located exactly as the original and required some work to make them fit and prevent shorting

  51. Darrell Grant

    Works as advertised.

  52. mathom

    Although this battery is advertised to work with the wheelchairs it doesn’t appear to be a perfect substitute for the original batteries. Ever since installing these, I have had problems with the controller inaccurately reporting the amount of charge in the battery. It swings all over the place within a few minutes. I have also had many instances where the wrench light on the controller comes on and I have to turn the chair off and back on to get it to move again. All in all I am not comfortable using the chair away from home without somebody else being there in case I have problems. I would not buy these again.

  53. vince west

    This has been working great and got here very quick.

  54. the tester person

    Good product fit & worked great

  55. John C.

    Just what I wanted, good price, will probably deal with them again!
