UPS Battery Replacement Turns Into Unrecoverable Firmware Update

As the saying goes, if it is not broken do not fix it, especially when it comes to firmware.

I have a couple APC Smart-UPS’s at my house, same as the models I like to use at the office. I use the SMT750 models with AP9631 Network Monitoring Cards. The problem started when we had a short power outage, and the UPS that powers the home network switch, cell repeater, alarm internet connection, and PoE IP cameras, unexpectedly died. A battery replacement led to the opportunity to do a UPS firmware update, which led to an unrecoverable firmware update.
