Your SMC3000RMI2U is still doing its job, but the battery inside it isn't giving you the runtime it used to. This is the exact APC #151 cartridge that unit was designed around — 12V DC, lead-acid, enclosed in a metallic tray so it seats cleanly. One cable, all connectors included. Swap it in and your rack UPS is back on full backup. Three to five years of life. Two-year warranty on the cartridge itself
