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!

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.
