Premium 12V lead-acid cartridge #43 (2 pack)

This PowerWarehouse two-pack supplies direct-replacement 12V lead-acid cartridges numbered #43 for the APC DLA3000RM2U UPS. Each unit is built to match the original equipment specifications so the uninterruptible power supply restores full runtime after installation. The pair covers both battery positions in the compatible chassis.

Upgrade from depleted or ageing #43 cartridges

Replace the existing #43 cartridges when runtime has fallen below acceptable levels or when the UPS signals a battery fault. The jump is worth it if the current set no longer holds charge through the required outage window. Buyers who need a different cartridge number or a higher-voltage pack cannot use this kit.

Questions about this item

Will the 12 V cartridge #43 slide into the APC DLA3000RM2U battery bay without modification?

Yes — the cartridge is built to the exact dimensions of the original RBC43 so it seats directly in the DLA3000RM2U tray.

What is the installation step most people miss when swapping the two cartridges?

Reconnect the internal jumper between the two batteries before closing the cover; the UPS will not start if that link is left open.
