CyberPower RB1270X3A UPS Replacement Batteries

The CyberPower RB1270X3A is a replacement battery cartridge that restores the full backup capacity of a compatible CyberPower UPS, including the CyberPower M750L. It arrives pre-assembled with three 12 V, 7 Ah sealed lead-acid batteries, so you can swap it in quickly and bring your system back online without delay.

The cartridge uses a design that is maintenance free and leak proof, which means there is no need to add fluid and no worry about spills. Open the UPS, remove the old module, slide in the RB1270X3A, connect the leads, and you are finished—no special tools or expertise required.

Once installed, the fresh batteries help your UPS keep computers, networking gear, and other sensitive electronics running smoothly during outages and brownouts. The shipping box doubles as a return container for recycling the spent batteries, making disposal straightforward and environmentally responsible.

CyberPower certifies that this cartridge meets or exceeds original performance standards and backs it with an 18-month limited warranty, giving home offices and small businesses confidence in reliable protection.
