    This was a exact replacement battery for our backup generator. Came with terminal nuts and bolts so it was a easy clean install with the current battery cables.

    Used for car jump box from Costco. Fit is similar, and power seems right.

    I bought this to replace the battery in a utility jump-starter, air compressor piece of equipment which is rarely used. I only know that it fits exactly as advertised and seems to be working great. If I’m lucky I’ll never actually depend on this thing helping me with my car, and will never have to learn about its longevity.

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
