Solid battery for my truck
The Mighty Max MM-G31 battery has been a real workhorse in my truck. At 100Ah and 900 CCA, it starts up effortlessly even in cold weather. Plus, the AGM design makes it spill-proof, which is a big plus for my needs.

Battery stopped working after 6 months
I was really optimistic about the Mighty Max battery, but it stopped holding charge after only six months of use. I followed all charging guidelines, so I'm pretty disappointed. Wouldn't buy again unless I get a replacement.

Not the best customer service
The battery itself works fine, but I had some questions about installation and customer service was slow to respond. It’s a solid product, but I wish the support had been better. Just be prepared for that.

Good performance but slightly heavy
I installed this Mighty Max battery in my RV. It works well and provides reliable power with 140RC, but I didn’t expect it to be as heavy as it is. Just a heads-up for anyone who might have trouble with weight during installation.
