My fiber optic cable battery back up have out before this did when the power went out so who knows how long it would have lasted but I sure was happy while it was on during the winter storm !

I had an elevator installed in 2011 with this UPS. Dec 2013 the elevator failed and I had to climb up to the top to track the problem down to a failed UPS. This unit was an exact replacement. 20 minutes to change out. System works now. Not sure about battery replacement or battery life.
