Questions about this item

How often will the 12V7A battery in this cartridge need to be replaced under normal use?

The 12V7A battery typically lasts three to five years before capacity drops enough to require a new cartridge.

What limit appears first when the SU420S runs on battery power during a long outage?

The 12V7A capacity determines runtime; once depleted the UPS shuts down until mains power returns.
