Replacement Cartridge for APC UPS

The PowerWarehouse APCRBC163-PW is a new sealed lead-acid battery cartridge built to replace APC Battery Cartridge #163. It fits the BR1500MS, BR1500MS-TW and BR1600SI uninterruptible power supply units. The maintenance-free design eliminates the need for fluid checks during its service life.

Leak-Proof Construction and Form Factor

The sealed case prevents electrolyte leakage in any mounting orientation, protecting rack or floor equipment from corrosion. At 11.50 inches long, 2.50 inches wide and 4.25 inches high, the cartridge slides into the UPS battery bay without modification. A weight of 12.6 pounds gives a solid feel during installation.

Lead-Acid Chemistry Limits Runtime

Sealed lead-acid chemistry delivers reliable backup but stores less energy per kilogram than newer chemistries, so extended runtime requires additional external battery packs. Capacity fades gradually with each discharge cycle and higher ambient temperatures accelerate aging. The 18 month warranty period reflects the expected service window under typical office conditions.
