  1. Betty Hillard

    First battery was bad they replaced no problem right a way good company.

  2. brian Ohlis

    I bought is battery and USPS said they delivered it…never received it and filed a claim with USPS. After two weeks of horrible customer service with USPS they wouldn’t do anything about it. Mighty Max Battery had my back the entire time with amazing follow Up. After all of this USPS would not do anything and Mighty Max Battery is sending me another replacement at no cost even though it was not their fault. Amazing company!!!!! I would recommend them for anything they sell. Thank you Might Mad Battery.

    Every time I try 2 USE it THE BATTERY DIDN’T have a Neff charge 2 start my jeep

  4. Kenzie batt

    The shop I work at was throwing a jump starter away, took it apart and check out the battery, for same battery it’d be $199. This battery works for the JNC66D which is a autozone or advanced brand they sell and it fits almost perfect, just a bit more snug but all in all exactly the same for a fraction on the price. Very happy

    Arrived on time, easy to install, I did the swap myself. It is exact replacement for ES5000 battery.

    This battery saved me from buying a new jumper.

  7. SAM

    My husband converted a electric generator to gas and needed a new battery. This fit the bill and it works great. We would purchase this again.

    Easy installation but you will need to bend the leads to match the terminal locations on this battery. Can be done with no risk of shorting anything in the booster. So far held charge for 2 months. I usually charge after each use or every month. Hope it lasts as long as the original battery which costs as much as a new booster pack!

    It was an exact fit and my unit is like new. I haven’t had it long enough to rate the Longevity and Battery Life but so far so good.

  13. travis mueller

    Great replacement.

  14. Nuv

    No complaints so far. Packaged nicely correct size and full bars. Definitely beats buying one from a local battery store for 70-120 bucks. This was installed in a ES5000. Hardware provided for terminals.

    Okay

    The battery, other than the original, is an exact replacement for what I needed.

  30. Alaskan buyer

    Just installed in my booster pac brand ES5000. Fit just as factory battery. The positive and negative posts were closer to the outer edges compared to the original battery which were about 3/4 closer to the center but cables still reached and everything tucked back into place without restricting reassembling of back cover. I Saved the original threaded studs, washers, lock nut and nuts to reused. Great way to reduce waste and save money at the same time.

    Works great

  33. Jade Dela Cruz

    Shipping was fast and I was able to change the battery on my power pack. Defiantly recommend this, instead of buying a new power pack.

  35. Joseph K.

    You need to make a slight modification to mount it to the original jumper case

    Came with a good charge and I put a load tester on them and they held over 12 volts.

  43. don hutto

    Works great

  44. Peter

    Installed with a few gentle nudges. All needed hardware fit. Still holding charge after 3 months. Too soon to tell if it’ll work as the original – haven’t found a dead auto to try it out… Either way, will comment again.

Ordered from Amazon- fast delivery. Installation was quick & easy. It started my motorcycle right away, but I put a smart charger on the battery to top it off.
Our two Mighty Max ML8-12 batteries arrived on-time and I installed them in a gate that opens and closes daily. We have a solar panel on the gate to recharge the batteries. We're hoping the batteries last longer (11 months) than the prior batteries from another battery company. These Mighty Max batteries are exactly the same specification as the batteries from another battery company. Crossing our fingers
Great product! Works very well
I am using these batteries for solar powered gate opener. These are used outside in a box to stay out of the weather.
Could not have faster shipping super price. Thanks again.
Thank you!
Battery arrived perfectly, brought my favorite speaker back to life!
Seems like a nice battery and arrived quickly. Only gave it four stars because longevity unknown, as I just installed it. Came fully charged and started my Yamaha triple right up!
I tried to post a review but the link would not let me. So, I already registered my battery and the battery seems to be working ok. I would like to receive my extra (3) months warranty, thank you. -James Lane
It was well packed, came fast
