    After several years the starting battery for my 8000 watt Dewalt generator died. This battery fit it perfectly. Replacing it was a bit of a pain but that’s just because Dewalt chose to make it more difficult to replace than it needed to be.

    Good value. Worked and fit like OEM battery. Time will tell on if the battery will have the expected 5-6 years of useful life.

These batteries were purchased for a razor motorcycle. They work wonderful and were easy to install! Our little man is happy to be back riding
Perfect fit and ready to go.
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.
