Direct replacement for SMT1500RM2UC

The APC APCRBC159 is a new lead-acid battery cartridge designed to restore runtime to compatible Smart-UPS units. It arrives ready to install without additional wiring or configuration. This cartridge suits administrators who need to bring an existing UPS back to specification after the original cells have aged.

Sealed lead-acid chemistry runs without liquid

The cartridge uses valve-regulated lead-acid cells that do not require watering or venting in normal operation. Heat generated during charge and discharge cycles is dissipated through the UPS enclosure, so no external cooling is added. Power draw during recharge follows the host UPS charging profile, keeping acoustic impact unchanged.

Black plastic housing matches the original form

The unit measures 50.0 in x 50.0 in x 28.0 in and weighs 12.6800, matching the footprint the UPS bay expects. Connectors are keyed to prevent reverse insertion, and the cartridge slides into the front-access compartment without tools. Buyers who need a different voltage, capacity or form factor will not be served by this part.

Questions about this item

How do I install the APCRBC159 cartridge in my SMT1500RM2UC UPS, and which step is commonly missed?

Power down the UPS, remove the front bezel, disconnect the old cartridge connector, slide the new APCRBC159 in until it locks, reconnect the connector, replace the bezel, then run the self-test — the step often skipped is the self-test that clears the replace-battery indicator.

What maintenance will the APCRBC159 lead-acid cartridge need during its service life?

No routine maintenance is required; the sealed lead-acid cells are maintenance-free, but plan to replace the entire cartridge again after three to five years depending on temperature and discharge cycles.

What is the first limit I will hit if the UPS runs on this cartridge through repeated long outages?

The 1500 VA runtime capacity drops as the batteries age, so the first limit is reduced backup time — once the self-test reports a weak battery, the cartridge must be swapped.
