    Battery is good price point, I am a repeat customer. The first one I ordered was defective, however company quickly replaced it. I definitely like a company that stands 100% behind their products. I will update after 6mths.

    This was quickly shipped and well packaged. I do not know how long it will last, as I just received but I imagine it will be fine as it is rechargeable.

    Battery was delivered in great condition as described. Price of battery was the lowest I could find with Prime. I needed the battery for my outdoor fountain and after installing my fountain worked great. I would definitely buy again.

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
