Compatible UPS Battery Replacement

This 12 V, 5 Ah sealed lead-acid battery serves as a direct replacement for the APC DLA3000RMl2U cartridge number 43. It is built for server-room UPS units that require a maintenance-free power source with the same voltage and capacity ratings. The PowerWarehouse LEADACIDSLA43-23 fits the specified cartridge slot without modification.

Upgrade From Expired Cartridge

The unit replaces an exhausted original battery when runtime has fallen below acceptable levels or the UPS signals a replacement alert. Swapping the cartridge restores full backup time for the connected load. It is not suitable for UPS models that use a different cartridge form factor, voltage or ampere-hour rating.
