APC RBC50 Replacement Battery Kit — 2 Battery Rebuild Set
Two 12V 18Ah AGM Batteries  •  For APC RBC50 Rebuilds  •  Reuses Existing Tray & Harness

Rebuild your existing APC RBC50 battery assembly with a fresh matched pair of two (2) 12V 18Ah sealed lead-acid AGM (VRLA) batteries. These replacement batteries are intended for compatible APC RBC50 applications and allow you to renew the battery pack while reusing serviceable cartridge hardware.
