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

    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!

Been ordering batteries from mighty max for several years now. They always perform just as well and last as long as any name brand battery they replaced! Very happy customer!

Purchased from Amazon, arrived within 3 days. Easy to install, great fit! Used all weekend in Honda generator, while camping at the race track. Worked like a champ, great value for the money.

These mighty max batteries are less than half the price of the ones that came with the power chair! They charged up fast and they are holding the charge good! I’ve used mighty max batteries for years in my electric gates and have never been disappointed!
