12V 7AH UPS battery

The APC RBC40 is a 12V 7AH sealed lead-acid replacement battery designed for compatible APC UPS units. It uses a maintenance-free design with suspended electrolyte for leakproof operation. The battery delivers an 87 volt-amp-hour capacity and a 12.0V output. Expected service life ranges from three to five years.

Fits CP16, CP24 and CP27 models

This battery suits owners of the listed CP16U, CP24U and CP27U UPS models who need a direct replacement. It includes all required connectors and a reusable package for the old unit. Installers who lack the listed model numbers should verify compatibility before purchase. Units requiring a different voltage, capacity or form factor cannot use this pack.

87 volt-amp-hour capacity

The 87 VAH rating determines how long the UPS can sustain its load during an outage. A lower capacity would reduce runtime while a higher one would not fit the chassis. Match this figure to the original battery specification to ensure correct autonomy. The 12.0V output must also match the UPS input requirement.
