Kit for CyberPower UPS Units

This replacement battery kit supplies two 6 V 9 Ah sealed lead-acid cells that match the CyberPower RB0690X2 specification. It is intended for users who need to restore backup power to compatible CyberPower UPS models without sourcing individual batteries.

Two 6 V 9 Ah high-rate discharge cells

The pack contains exactly two batteries rated at 6 volts and 9 ampere-hours each, wired to fit the original cartridge footprint. That voltage and capacity combination is the single figure that determines whether the kit will work in a given UPS.

Printed installation guide included

A step-by-step instruction sheet walks through the cartridge swap so the UPS can be returned to service quickly. No additional tools, cables or software are bundled with the kit.
