Direct APC RBC23 Replacement

This maintenance-free lead-acid battery matches the RBC23 cartridge specification and is built for APC uninterruptible power supply units. It installs without modification and restores backup runtime for servers, network gear and workstations. Buyers needing a different form factor or a lithium-based chemistry should look elsewhere.

Sealed Low-Heat Operation

The sealed lead-acid design produces minimal heat and no audible fan noise during normal float charging and discharge cycles. Power draw stays limited to the UPS charger current, so the unit adds no extra thermal load to the rack or cabinet.

Questions about this item

How is the PowerWarehouse LEADACIDSLA23-04 installed in an APC RBC23 cartridge, and what step is often missed?

Remove the old battery pack, connect the red lead to the positive terminal and the black lead to the negative terminal, then secure the replacement; the step often missed is tightening both terminal bolts to prevent loose connections.

What maintenance or replacement will the PowerWarehouse LEADACIDSLA23-04 need later?

As a sealed lead-acid unit it is maintenance-free, but plan to replace it after three to five years or when runtime drops below acceptable levels.
