Compatible APC SC450RM1U Battery Kit

This replacement battery kit is designed for the APC SC450RM1U uninterruptible power supply. It contains two 6V 9Ah batteries that match the original RBC18 specification. The kit suits administrators who need to restore backup runtime on an existing unit.

Drop-in fit for existing UPS

The two batteries install directly into the SC450RM1U chassis without extra cabling or mounting hardware. Replacing the cells restores the UPS to full backup capacity and frees the rack from the risk of an unexpected power loss.
