CyberPower RB1290X4F UPS Replacement Battery Package

The CyberPower RB1290X4F is a replacement battery package that refreshes and restores the performance of select CyberPower uninterruptible power supplies. It arrives as a single, pre-assembled cartridge that holds four batteries, so you spend minutes—not hours—getting your UPS back online. Each battery is a sealed lead-acid unit rated at 12 V and 9 Ah, matching the original factory specifications to preserve run-time and load capacity.

This package was built with day-to-day users in mind. The maintenance-free design never asks for replacement fluids, and the leak-proof casing keeps the batteries protected whether the UPS sits on a server rack, under a reception desk, or in a home office. CyberPower also ships the RB1290X4F in reusable packaging that doubles as a safe way to send your spent batteries to a recycling center.

Installing the cartridge is straightforward. Slide the old module out, slide the new one in, reconnect the terminals, and your UPS is ready to safeguard routers, network switches, security cameras, and other critical gear against power interruptions. Small businesses, remote workers, and IT managers who rely on consistent uptime will appreciate the peace of mind and the 18-month warranty that comes with every unit.

Because the RB1290X4F meets or exceeds original manufacturer requirements, it integrates smoothly with several CyberPower UPS models. Check your user manual or the model number on your existing battery to confirm compatibility, then keep an extra cartridge on the shelf so battery swaps never catch you off guard.
