What this cartridge restores

The RBC51 cartridge fits a variety of UPS brands and returns the unit to its original runtime specification. It ships in reusable packaging that holds the expired cells for recycling centre delivery. Buyers who need a model-specific pack not covered by the compatibility list cannot use this cartridge.

Leakproof build and everyday handling

Rugged, leakproof construction keeps the cells sealed during normal operation and transport. The maintenance-free design means no fluid checks or top-ups are required. The 3.69 by 5.88 by 2.50 inch footprint and 7.10 lb weight allow one-person installation in most standard battery bays.

Temperature range and power profile

The cells operate from 0 to 95 percent relative humidity non-condensing and at elevations up to 10,000 ft or 3,000 m. Storage is rated to 50,000 ft or 15,200 m. OEM-certified premium chemistry delivers up to 30 percent longer runtime than basic replacements under the same load.
