Questions about this item

How often will the two 12 V 7 Ah cells inside the APCRBC123 cartridge need replacing?

Sealed lead-acid cells typically last three to five years; the UPS will signal when runtime drops below the configured threshold.

What limits runtime first during a prolonged outage on the BX1350 or SMT750RM2UC?

The 7 Ah capacity sets the energy ceiling; once the stored charge is depleted the UPS shuts down regardless of load.

How much heat does the cartridge add when the UPS runs all day on mains power?

Float charging the 24 V pack produces only a few watts of warmth, so the battery adds negligible heat to the rack or desk.
