    This backup battery is a perfect fit for my garage door opener which is a Liftmaster model 3850p. It is the same size as the original backup battery (485LM) and fits perfectly in the slot. Super easy to replace/install. This is a much cheaper price then getting an OEM replacement (485LM). Works great!!

We needed a replacement battery for our Game Day Speaker. I chose a Mighty Max 12V2.9Ah battery from Amazon. Ordered and had it here in 2 days. The battery arrived in perfect package and fully charged. We installed it in our speaker and are now ready to use again. Super Great Price! Will definitely use this company again!
Ordered a bundle of Mightymax ML5-12 to replace batteries in my 2200 va kvm. They fit well though the terminals were smaller than the batteries I'm replacing. Test worked fine and I'm satisfied. Thanks MightyMax!
Pleasantly surprised, battery arrived fully charged. Made it for a quick install!
Great experience with Mighty Max Battery. I use the ML35-12 Gel model for my MightyMule electric gate, and it’s a perfect fit. The shipping was fast—arriving a few days early—and the packaging was solid, with high-density cardboard and styrofoam protection.

The battery arrived fully charged at 13.06V and provides reliable cranking power even after the gate has been sitting. I also appreciated that the terminal hardware was included and securely attached. High value and great performance; I'd definitely buy from them again.
Quality product at a great price and received promptly!
Arrived next day, can’t wait to install this on my SSR Bison 200p. I have had so many issues with the 12v atv batteries.
Hope the battery works as good as it looks
Great deal on two of these batteries. Packaged extremely well. Put one on my generator and it started right up.
Works great installed easy and come pre charge.
