Arrived quickly from WALMART.COM. Perfect size and proper placement in my generator. Installation was easy. Generator fired right up. Battery came fully charged.

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
