    I love the price and it was easy to install. I cannot comment on longevity because I have not had it long enough.

    Battery appears fine no frills, only complaint would be it came with only one bolt and nut to connect. Not a big deal unless you are at the shed getting ready to put in and you dont have one. Then its another trip down the hill to find one and lake time is precious.

    Very nice battery. I used this as a replacement in my Cub Cadet 2160 tractor. Works like a champ. I really like the fact you don’t have to add water ever, as compared to the old one, this replaced.

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
