    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!

Good battery
Justin Harris
Great experience with Mighty Max Battery. I purchased a new battery for my child’s ride-on Jeep through Home Depot, and it was delivered quickly and arrived ready to go. Once installed, the Jeep was back to running at full power and the battery has been working great.

Very happy with the performance, delivery, and overall purchase. Couldn’t be happier and would definitely recommend Mighty Max Battery!

Good replacement for Firman Generator
Mark Morgan
Using it in my Honda eu3000 generator. Sorry no pocture can add later. But works perfect. Will be ordering more of these batteries. Works better than the store bought ones. Thank you for your quality product.

Quick delivery, packed well, and now charging…Looking forward to using on my Bat Caddy X4 Sport model!!! Thanks for an easy transaction…
david freyberger
Fit perfectly for a quarter of the cost. Make sure to use the correct connection terminals. An excellent replacement with more storage than OEM. APC was 4.5aH this one is 5.0aH same space and worked right out of the box. Save money and get this replacement for your APC BE425M. Your only 4 screws away from no more beeping!!
