Direct replacement for APC SUVS1400

The PowerWarehouse LEADACIDSLA7-21 is a maintenance-free lead-acid battery cartridge designed to replace the RBC7 unit in APC SUVS1400 uninterruptible power supplies. It restores backup runtime for servers and network equipment without requiring modifications to the existing UPS chassis.

Sealed design runs without venting

The sealed lead-acid construction eliminates electrolyte maintenance and allows operation in any orientation inside the UPS cabinet. Normal float charging produces minimal heat and no audible noise, while the chemistry delivers stable voltage across the 1400 VA load profile.

Questions about this item

How do I install the PowerWarehouse LEADACIDSLA7-21 battery into my APC SUVS1400 UPS, and what step is most often missed?

Power off and unplug the UPS, open the front cover, disconnect the old cartridge, insert the new LEADACIDSLA7-21, reconnect the terminals firmly, close the cover, then power on and let the UPS charge for the recommended period before relying on backup.

What maintenance or replacement will the LEADACIDSLA7-21 need later?

This maintenance-free lead-acid battery requires no water topping; plan to replace the cartridge after three to five years or when the UPS signals reduced runtime.
