Description

CyberPower RB1290X6D Replacement Battery Cartridge

Overview

The CyberPower RB1290X6D is a user-installable, maintenance-free replacement battery cartridge designed to restore runtime for compatible CyberPower Uninterruptible Power Supply (UPS) systems. It contains six 12V/9Ah sealed lead-acid batteries, pre-assembled into a leak-proof casing. This cartridge ensures your UPS can continue to provide critical backup power during outages, protecting sensitive equipment from data loss and downtime. Its design prioritizes ease of replacement, minimizing installation complexity.

Compatibility

This RB1290X6D battery cartridge is specifically designed for use with the CyberPower BP144VL2U01 UPS model. Note that the BP144VL2U01 requires two RB1290X6D units to achieve its full operational capacity and runtime specifications. Always verify your UPS model's service manual for exact battery requirements before ordering.

Installation Notes

The RB1290X6D is designed for user replacement, meaning no specialized tools or technician assistance are typically required. Ensure the UPS unit is powered off and disconnected from the AC source before attempting replacement. The cartridge features a leak-proof casing and is maintenance-free, simplifying the installation process. Reusable packaging is provided for convenient battery recycling.
