APC Battery Cells — for APC RBC46 Pack (NOT a Complete Cartridge)
These are individual AGM (VRLA) batteries — the same cell type used to populate an APC RBC46 battery module. They are not a finished RBC46 cartridge. Use them to rebuild your existing tray/harness if you wish to perform the replacement yourself.
Typical RBC46 modules are assembled from a single 12 V, 6 Ah cell.
This page is for loose cells only.
