  3. dennis watts –

    As described, shipped on time

  4. Web Customer –

    battery dead after 9 months and will not take a charge

  5. David D. –

    Fit like is should , it is only 2 weeks so other then that I have no idea

  6. Kindle Customer –

    Worked great while it lasted. After 1 year would not hold a charge, even though it was kept on a trickle charger.

  7. Customer –

    Great price

  8. Paul P. –

    Time will tell how this battery lasts, but initial impressions are good. I ordered two of these for my Arctic Cat Z570 snowmobiles. Both arrived in a timely fashion and when tested showed just shy of 12.9 volts on my volt meter. Once installed they cranked the snowmobile engines over with ease! I’ve spent more than twice this amount on batteries that only lasted a year, so if these last at least that long I’ll be more than happy!

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.

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.
