    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!

Solid looking battery, came well packaged. Have used their battery before for my lawnmower and now looking forward to see how it lasts in my snowmobile.

I can't believe it less than 48hrs since I ordered from Walmart and it's in the machine. What more can I say except great price.
Thanks Larry

So far these Might Max batteries are good but it’s only the first day and they were on charge for 12 hrs. I’ll have to come back and do an update at some point in time. Ordered them on Amazon and got them the next day. I was encouraged by Mighty Max to make this google review and post pictures to extend my warranty for 3 months but there is no way to post pictures 🤣🤣🤣 It’s been a few months and I was able to go back and edit, so here is a video I made, the rest of the photos I have deleted. Batteries are still going strong. Update 12-11-2025

They arrived within 2 days of ordering them packaging was really good I haven't put them in my MX350 yet I hit them with my multi meter fresh out of the box and got 12.4v on both batteries so that is good
