    Needed this for my generator. Replacement from the original company was quoted to me at $120. I don’t know how long this will last, but it will last for at least one hurricane season, I should imagine.

    I had a Harbor Freight 4-in-1 jumper box with a dead battery inside. This is the exact replacement battery for it, and was easy to swap out. Appears to work great afterwards. Felt like a waste to throw out the jump box when this was a reasonably affordable replacement.

    Battery arrived fully charged, at least as determined by the Cen-tech 4-in-1 Jump Starter. Nuts and bolts included for attaching, even though I just used the existing ones. Battery slipped right into starter unit, tight fit, but that’s what you want: snug. Will have to see 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
