Tiny AGM, short life - not RV
AGM battery in UPS in my home died after 5 years and zero cycles. Probably was dead for a while, only there was no power outage for the last 3 years. Yesterday blackout happened and it shut down immediately after beeping "battery overload". Old desktop - 100W? - was the only load. Saved me from (unlikely) surge but didn't give me time to properly shut down the desktop. Was never discharged, always plugged in or disconnected from grid power and loads when I'm not in town.
Battery is a few AH, costs ~$20, no big deal but 5 years with zero cycles?
UPS: Cyberpower 425VA.
