PowerWarehouse 2XRBC110SLA1108 Cartridge Pack

This twin-pack delivers two 12V lead-acid cartridges built to fit the APC BK650MC uninterruptible power supply. Each unit is manufactured to match the original equipment specifications for direct replacement. The batteries arrive new and ready for installation in compatible UPS systems. Buyers needing a different form factor or voltage should verify their hardware requirements first.

Two-Pack Replacement Kit Benefit

The paired configuration lets you swap both cells in a dual-battery UPS at the same time, keeping the bank balanced and avoiding mixed-age cells. Having the second cartridge on hand also reduces downtime if a future cell fails outside normal hours. Installers who prefer staggered replacement cycles can simply store the spare until needed. Users with single-battery UPS models will have an unused unit.

Questions about this item

When will the 12 V lead-acid cells in this #110 cartridge need replacing?

Under normal UPS duty the 12 V lead-acid cells typically last three to five years; plan replacement when runtime drops noticeably below the original 650 VA backup time.

What is the first limit reached during a long outage on the APC BK650MC?

The 650 VA / 12 V capacity of the UPS is the first limit; once the stored energy in the two cartridges is depleted the output shuts down.
