Compatible replacement for RCD-UPS300

This kit provides a direct replacement battery cartridge for the RCD-UPS300 UPS model. It contains a single 6V 4.5Ah sealed lead-acid unit built for high-rate discharge. The pack restores backup power to compatible uninterruptible power supplies.

Upgrades depleted original cells

The cartridge replaces the factory-fitted battery when runtime has fallen below usable levels. Swapping the module is worthwhile once the UPS can no longer sustain connected equipment during an outage. Installation instructions are included for straightforward user replacement.

Delivers 4.5Ah at 6 volts

Capacity supports typical low-load server or networking gear for the runtime the UPS was designed to provide. The high-rate discharge chemistry handles the brief, heavy current draws of a power failure. Runtime ends when the stored 4.5Ah is exhausted.
