VA ratings, runtime math, and managed shutdowns — buy the right battery once instead of the wrong one twice.

1. Add up the watts that matter

List modem, router, switch, server, and one workstation with their wattage (labels or a $25 kill-a-watt). Size UPS at 1.5x that total in VA — headroom handles startup surges and battery aging.

2. Buy runtime for shutdown, not workdays

Target 20–30 minutes: enough to ride out blips and shut down cleanly. All-day runtime needs generators, not batteries — mismatched expectations waste thousands.

3. Connect USB and configure auto-shutdown

USB cable from UPS to server/NAS with the vendor software set to graceful shutdown at 5 minutes remaining. Unmonitored UPS units just delay the crash; configured ones prevent it.
