  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.

  6. Hussle Man

    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!

    I did the swap myself , easy to medium difficulty its working good for me.

    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.

    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

  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.

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
