Compatible APC RBC3 kit

This compatible replacement kit provides two sealed lead-acid batteries rated at 6 volts and 12 ampere-hours each. It is designed to restore runtime to APC UPS units that use the RBC3 cartridge form factor. The kit suits administrators maintaining existing power protection without switching to original equipment manufacturer cartridges.

Factory-fresh sealed cells

Each battery arrives factory fresh and ready for immediate installation in the UPS chassis. The sealed construction prevents electrolyte leakage and allows mounting in any orientation required by the cabinet. A combined weight of 10 units reflects the dense lead plates needed for high-rate discharge during utility outages.

Included installation instructions

The package contains comprehensive step-by-step replacement instructions written for the specific cartridge layout. Following the guide lets maintenance staff swap cells without specialised tools or extended downtime. No additional software or configuration utilities are bundled with this hardware-only kit.
