    Bought this battery as a replacement in Sept 2016, Went bad by Feb 2019. We use it on Big Steel Double Gates that are powered by a solar panel. Buying a new one today. For a little over $100 bucks and getting over 2 years and 6 months, that is AWESOME! Thanks

    The title says AGM but I received a sealed lead acid. The battery itself is fine, but it is misrepresented in the title. Rather than go through the trouble of returning it, I’ll make it work.

Arrived in perfect condition
2011 Yamaha Raptor 700R battery, started right up. Has a 1 year warranty. Great deal.
Love mighty max batteries
Arrived well packaged. No information as to original warranty coverage and term, but lots of solicitations to extend the warranty coverage for a whole amazing 90 days - Wow, such product confidence! At least it’s not made in China, but is Thailand any better for quality manufacturing? We’ll see.

Arrived next day and sas very easy to install. They also offer free 3 warrany extension.
I ordered this MightyMax battery through Amazon. The Ad states it works in my GE Simon XT house alarm.
I received my battery from Amazon on March 9, 2026. The box was a little squashed but the battery was packaged well and it it fine. I installed it and finally my gate opener is working properly. I purchased 2 batteries before this and had to return them because they were the wrong battery. This one is working great.
Looks the part, I am charging it fully before install on my jet ski.
These batteries arrived in great shape with the handle on top so you can carry it screw so you can hook them up very professional looking better about them from Home Depot
