CyberPower RB1290X4D UPS Replacement Battery Cartridge

The CyberPower RB1290X4D is a replacement battery cartridge that restores reliable backup power to select CyberPower uninterruptible power supplies. It is designed for users who want a quick swap that brings their UPS back to full capacity without the hassle of buying and wiring individual batteries.

This cartridge ships ready to install. Inside the housing are four 12 V, 9 Ah batteries that use sealed lead-acid chemistry, so the electrolyte never needs topping up and routine maintenance is eliminated. The leak-proof casing keeps everything contained and helps the batteries reach their expected service life.

Installation is straightforward. Remove the old module, connect the new cartridge, slide it into the bay, and your UPS is back in service within minutes. Because the RB1290X4D meets or exceeds original specifications, you can depend on it to deliver the same runtime and performance you had when the UPS was new.

The cartridge fits CyberPower models with a blue LCD such as PR1500LCDRTXL2U, PR2200LCDRTXL2U, PR3000LCDRT2U, and PR3000LCDRTXL2U. Whether you manage a small server rack, protect network equipment in a wiring closet, or rely on a UPS for a home office workstation, this replacement keeps critical devices powered during outages and prevents data loss.

CyberPower includes reusable packaging that lets you send the spent batteries to a recycling center, making disposal simple and environmentally responsible. An 18-month limited warranty provides added confidence in long-term performance.
