PowerWarehouse 2XRBC21SLA214 12V UPS Battery 2 Pack

This pack supplies two sealed lead-acid cartridges rated at 12 volts each. They are built to match the APC RBC21 form factor and are guaranteed 100 percent compatible with the original equipment. The units arrive new and ready for immediate installation in supported UPS systems. A one-year replacement warranty covers the batteries.

Ideal for APC RBC21 UPS owners needing a direct swap

Administrators maintaining compatible APC uninterruptible power supplies can replace depleted cells without modification. Buyers whose UPS requires a different cartridge number or voltage should look at another product. Those needing a single battery instead of a pair will not find that configuration here. Operations demanding lithium chemistry or hot-swap trays are also outside the scope of this kit.
