PowerWarehouse 2XRBC18SLA183 UPS Battery

This PowerWarehouse 2XRBC18SLA183 pack supplies two 6V lead-acid cartridges built for the APC PS450 uninterruptible power supply. The batteries are guaranteed 100% compatible with the original equipment and arrive new with a one-year replacement warranty.

Replaces worn APC PS450 cells

Swapping these cartridges restores runtime when the existing pack no longer holds charge after extended service. The jump is worth it when the UPS self-test fails or backup time drops below what the connected load requires. Buyers needing a different voltage or form factor should verify their specific model before ordering.
