“How long does the back up battery tend to last?”

1-2 of 2 Answers

• It really depends on how many and what kind of devices are plugged into it. If you are powering an internet modem it should run for hours or days. If you are keeping a pc running it could be only minutes or hours.

• The APC Back‑UPS BN450MNW (450 VA / 255 W) is designed for short‑duration backup, just long enough to keep small devices running or allow a clean shutdown. The actual runtime during a power outage depends entirely on the connected load. You may check the link below for the UPS estimated run time for your reference.
