Replacement Battery for APC UPS Units

This sealed lead-acid battery cartridge replaces the APC RBC6 and Battery Cartridge #6 in compatible Smart-UPS and Back-UPS models. It fits units such as the SMC1500, SMT1000, SU1000 and SUA1000 series. The maintenance-free design is leak-proof and arrives ready to install. Dimensions are 7.70" L x 6.00" W x 3.70" H and weight is 16.90 lbs.

Upgrading from an Exhausted RBC6 Cartridge

When the original RBC6 battery no longer holds a charge, this direct replacement restores full runtime to the UPS. The jump is worth it when the UPS reports a battery fault, runtime drops below acceptable levels, or the unit reaches the typical three-to-five-year service interval. No firmware updates or hardware modifications are required for the swap.

Limits of the Sealed Lead-Acid Format

The cartridge uses valve-regulated lead-acid chemistry, which is heavier than lithium alternatives and requires upright mounting. Capacity degrades with deep discharges and elevated temperatures, so regular self-tests are advised. The 18-month warranty covers manufacturing defects but does not extend to wear from excessive cycling. Buyers needing longer cycle life or lighter weight should consider UPS models designed for different battery chemistries.

Questions about this item

Will the 7.70 x 6.00 x 3.70 in dimensions and 16.90 lbs weight fit my APC SMT1000 UPS battery compartment?

The RBC6-PW matches the 7.70" L x 6.00" W x 3.70" H and 16.90 lbs specifications of the original Battery Cartridge #6, so it fits the SMT1000 and all listed APC Smart-UPS models.

How do I install the RBC6-PW in my SUA1000, and what step do people often miss?

Power off the UPS, open the front battery door, disconnect the old cartridge's Anderson connectors, slide in the new RBC6-PW, reconnect the red-to-red and black-to-black leads firmly, then close the door — the step often missed is tightening the connector screws to prevent loose contacts.

When will the sealed lead-acid cells in this RBC6-PW need replacement under normal use?

As a maintenance-free sealed lead-acid cartridge, the RBC6-PW typically delivers 3–5 years of service; plan replacement when runtime drops below 50 % of original or the UPS reports a battery fault.
