Questions about this item

Does the PowerWarehouse LEADACIDSLA43-09 arrive ready to install or are extra cables needed?

The 12V 5Ah unit is a direct drop-in for the APC RBC43 cartridge #43 and ships fully assembled with terminals fitted, so no additional cables or connectors are required.

My APC Smart-UPS 3000 uses four 12V cells — is this the correct single replacement?

Yes, each LEADACIDSLA43-09 is a 12V 5Ah block; the SLA3000R2X401 pack contains four of these cells, so order one per position you need to refresh.
