    This was a must have for a 4wheeler that sat for 5 years. Installed and cranked engine extremely fast. No charge to the battery out of the box. Very fast shipping and i am very satisfied!

    Battery arrived quickly and I test-fitted it in the bike before putting it on the trickle-charger (like I do all new batteries). Then when I put it in the bike and hooked it up, it worked just as it was supposed to. The Warrior has a pull-start too, and I had been using that the previous 2 desert trips, but this battery makes it a WHOLE LOT more convenient! The price is competitive,and I also purchased the optional additional 3-year extended warrantee through (just in case). I’d recommend this battery to anyone looking to replace the battery in their Yamaha Warrior.

Excellent
Mighty Max Battery
Based on 3474 reviews
Arrived quickly. Even got a sticker with 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
Item as described and perfect fit and arrived on time
Battery arrived in a good shape package strait to my door steps
Arrived just in time to power my generator here in the cold Maine winters. Excellent service!
Arrived quickly from WALMART.COM. Perfect size and proper placement in my generator. Installation was easy. Generator fired right up. Battery came fully charged.
New battery. Ready for cold weather!
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
