Compatible UPS Battery Pack

The PowerWarehouse 2XRBC33SLA3310 is a 24V lead-acid cartridge designed to fit the APC BR650CI uninterruptible power supply. It arrives as a matched pair so both cells can be swapped at once, restoring the original runtime without mixing old and new modules. Installation follows the manufacturer's standard procedure for this UPS model. Buyers who need a different voltage or a single-unit replacement should look elsewhere.

Thermals and Power Draw

The sealed lead-acid chemistry operates passively with no internal fan, so it adds no audible noise to the UPS enclosure. Heat output stays low during normal float charging and brief discharge cycles typical of desktop or small-server protection. Power draw is limited to the UPS charger current, keeping energy overhead minimal. No active cooling or special ventilation is required beyond the cabinet's existing airflow.

Questions about this item

How do I install the two 24 V cartridges into my BR650CI without reversing the polarity?

Power down and unplug the UPS, open the battery door, remove the old cartridge, insert each new 24 V pack with the red lead to the positive terminal and black to negative, then close the door and restart.

When will the lead-acid cells in cartridge #33 need replacing again?

Expect three to five years of service; plan replacement when runtime drops below half of the original 650 VA rating or the UPS signals a battery fault.
