    Replaced the old battery in our alarm panel, fits inside fine. Works great, no more battery alerts, holds the charge, and keeps us going during power outages.

Excellent
Mighty Max Battery
Based on 3770 reviews
Arrived as scheduled. Installed and works exactly as described. Would recommend.
My order was delivered faster then expected, the battery is during the job that I purchased it for, I am happy with my purchase.
Fit good looks good it’s new so I have no idea of long term survival yet . Generac xg8000e.
Works great in my chicken coup for the timed winter light—A+!!!
Had a power outage during the freeze that occurred in Texas in January 2026, and my UPS switched over to it's battery with no issues. However after the power came back I noticed the battery was refusing to charge. I looked online for a replacement and came across Mighty Max Battery and looked at other reviews for the specific model I was looking for and saw nothing but great things. I ordered my item and it shipped very fast and was able to swap out my old OEM battery for the Mighty Max replacement and it's proving to be as good if not better than the OEM model I had. I'm expecting it to last a very long time. Thanks Mighty Max Battery!
Great battery for the price
Just received a new 12v 18mA Mighty Max from Amazon for my Champion genset. Perfect replacement for the same battery purchased in 2019 (lasted 6+ years) which replaced the Original battery which lasted just 2 years.
Really good product
Great fit works as expected
So easy to replace old battery with new one.
