The APC APCRBC124 is a maintenance-free sealed lead-acid cartridge designed for hot-swap replacement in compatible uninterruptible power supplies. It fits units including BR1200G-FR, BR1200GI, BR1300G, BR1500G, BR1500G-FR, BR1500GI, SMC1000-2U and SMC1000I-2U. Installation uses the supplied connectors and guide.

Spill-proof chemistry runs without routine upkeep

Expected service life spans three to five years under normal operating conditions.

Buyers needing a different form factor or higher capacity for other APC models should verify their UPS part number before ordering.

Questions about this item

How do I install the APCRBC124 cartridge, and what step do people often miss?

The cartridge is hot-swappable, so you can replace it while the UPS stays on; the step users miss is connecting the recycling guide's return label so the old pack ships back to APC at no cost.

What maintenance or replacement will the APCRBC124 need later?

It is a maintenance-free sealed lead-acid pack rated for three to five years; after that window the whole cartridge must be swapped again, as individual cells are not user-serviceable.

What limit appears first on the APCRBC124 during sustained use?

The chemistry caps service life at five years or the point when runtime drops below the UPS alarm threshold, whichever arrives first under continuous load.
