Compatible APC NS2200RM3U battery pack

This PowerWarehouse 2XRBC12SLA126 pack supplies two 12 V 126 Ah lead-acid cartridges built for the APC NS2200RM3U uninterruptible power supply. Each unit is guaranteed 100 % compatible with the original equipment so installation is a direct swap. The pair gives administrators a ready spare set for critical rack-mount infrastructure.

Sustained discharge reliability

Lead-acid chemistry delivers steady voltage through extended outages rather than a brief surge, keeping servers online until generators start or graceful shutdown completes. The 126 Ah rating supports long runtime at constant load without the voltage sag seen in high-rate designs. One-year replacement coverage backs the expected cycle life.

Questions about this item

How much heat does the 12 V 126 Ah cartridge generate during continuous UPS operation?

The sealed lead-acid cells produce minimal heat under normal float charge; the metal case acts as a passive heatsink so no active cooling is required.

Which APC UPS model must I already own for this 2-pack to fit correctly?

The cartridge is designed specifically for the APC NS2200RM3U rack-mount UPS and will not fit other models.
