Direct-fit APC APC3RA battery pack

This two-pack of 12 V sealed lead-acid cartridges is built to match the original APC APC3RA specification. Each unit slides into the UPS without adapters or wiring changes. It serves administrators who need a drop-in refresh for existing backup units.

Sealed chemistry runs cool and quiet

The valve-regulated design produces no audible fan noise and minimal heat during normal float charging. Internal resistance stays low so the UPS draws only the current needed for maintenance charging. No extra ventilation or cooling allowance is required beyond the cabinet’s standard airflow.

Questions about this item

How do I install the 12V lead-acid cartridge into my APC APC3RA UPS, and what step is often missed?

Power down the UPS, remove the front panel, disconnect the old cartridge, insert the new 12V unit, reconnect the terminals, replace the panel, then turn the UPS back on and let it charge fully.

What maintenance will the 12V lead-acid batteries need later, and when should I replace them?

Lead-acid cells degrade over time; expect to replace the pair every three to five years or when runtime drops noticeably, and keep the UPS in a cool, dry place to maximise service life.
