CyberPower RB1290X3R UPS Replacement Battery Cartridge

The CyberPower RB1290X3R is a factory-assembled replacement battery cartridge that restores the runtime and reliability of compatible CyberPower uninterruptible power supplies. Inside the module are three 12-volt, 9-amp-hour sealed lead-acid batteries that match the performance standards set by the original equipment, so your UPS can deliver the backup power it was designed to provide.

The sealed construction keeps the batteries maintenance free, and the leak-proof casing protects nearby electronics from accidental spills. Installation is straightforward: slide the old cartridge out, place it in the reusable shipping box for recycling, and push the new RB1290X3R into the UPS. No special tools or extensive downtime are required, making the swap easy for IT technicians, small business owners, or anyone managing a home office setup.

CyberPower backs the cartridge with an 18-month limited warranty, giving you added confidence when outages or voltage fluctuations threaten your equipment. If you run network gear, security systems, or point-of-sale terminals that must stay online, this cartridge helps ensure your UPS can keep them powered until utility service is restored.
