PowerWarehouse 12 V dual-pack for APC SU3000RMTX136

This two-pack supplies 12 V lead-acid cartridges built as direct replacements for the APC SU3000RMTX136 UPS. Each unit is guaranteed 100 % compatible with the original equipment so installation requires no wiring changes. The set restores backup power for rack-mounted servers and network gear that depend on this specific UPS model.

Sustained discharge behaviour

Under continuous load the sealed lead-acid chemistry delivers steady voltage until the cells reach their safe cutoff point. The 100 % compatibility guarantee means the internal resistance matches the UPS charging profile, preventing premature thermal shutdown during extended outages. Buyers who need longer runtime than a single cartridge provides should verify whether their UPS chassis accepts additional battery modules.

Questions about this item

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

The sealed lead-acid cells produce only modest warmth under normal float charge; the APC SU3000RMTX136 chassis handles dissipation without extra cooling.

What existing hardware is required to install the 2-pack in the SU3000RMTX136?

You need the original APC SU3000RMTX136 UPS with its battery compartment and mounting rails; the cartridges slide straight in using the factory connectors.
