    It didn’t fit and I waited too long to return it. We will see if it fits one of the riding mowers

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.

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.
