    These are great batteries I’m getting right at 4 years of life out of them. Other brands I’ve used only lasted me about 2 years. Got them in my 4 bikes some bikes sit for a little while but the batteries always hold there charge n crank right up.

    This is an excellent value. The battery came fully charged and is preforming better than expected. I am using this in a snowmobile, it seems to tolerate cold weather very well.

    The body was just slightly fatter and the posts slightly skinnier, but the unit feels very solid. Cables went right on without a fuss. I did have to shim one of the nuts to get the screw to bite. Sled cranked right over and I am very happy with the fit. I will try to come back to this review after I put a few seasons on it.

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
