CyberPower RB0690X4 Compatible Kit

This RefurbUPS battery kit replaces the CyberPower RB0690X4 cartridge with four factory-fresh 6V9A sealed lead-acid cells. It is designed for administrators who need to restore runtime on compatible CyberPower UPS units without sourcing individual batteries.

Jump from aged or swollen cells

When existing batteries no longer hold charge or show physical swelling, this kit restores the original backup duration. The upgrade is worth it when the UPS electronics remain functional but the cells have reached end of life.

Four 6V9A cells provide the rated capacity

The matched set delivers the voltage and ampere-hour rating the UPS expects for its designed load profile. Runtime will decrease once the connected equipment exceeds the UPS rated output or when the cells themselves age beyond their service interval.
