CyberPower RB1290X6B UPS Replacement Battery Cartridge

The CyberPower RB1290X6B is a replacement battery cartridge that restores the full backup capacity of a compatible CyberPower UPS. It arrives as a single, ready-to-install unit, allowing you to keep critical equipment protected without lengthy downtime.

Inside the sturdy housing are six batteries, each rated at 12 V and 9 Ah. The sealed lead acid chemistry removes the need for fluid checks, and the leakproof construction keeps the batteries secure in server rooms, network closets, and other demanding environments.

This cartridge is engineered for the CyberPower BP72V60ART2U external battery pack. That UPS requires two RB1290X6B units for a complete refresh, and because the cartridges are pre-wired, technicians can complete the swap in minutes. The quick change is a practical advantage for IT managers, small business owners, and anyone who relies on steady power for servers, phone systems, or point-of-sale terminals.

CyberPower ships the RB1290X6B with reusable packaging, making it simple to send depleted batteries to a recycling center and meet sustainability goals. The cartridge is OEM certified and backed by an 18-month limited warranty, providing confidence that performance will match or exceed the original specification.
