APC Battery Cells โ€” for APC RBC35 Pack (NOT a Complete Cartridge)
Loose Cells Only ย โ€ขย  AGM (VRLA) ย โ€ขย  12ย V SLA Cell ย โ€ขย  For Rebuild/Service Use

These are individual sealed lead-acid AGM (VRLA) batteries โ€” the same cell type used to populate an APC RBC35 battery module. They are not a finished RBC35 cartridge (no tray, harness, or enclosure included).

Use this loose cell to rebuild your existing RBC35 tray/harness if you wish to perform the replacement yourself, or as service spares for technicians maintaining APC Back-UPS battery modules.

Important
  • This page is for loose cells only. You will reuse your existing tray/harness/enclosure.
  • Typical RBC35 modules are assembled from one (1) 12ย V, 3.5ย Ah cell.
  • Verify dimensions and terminal type before ordering.
  • Installation involves battery handling โ€” follow UPS/battery safety procedures and local disposal regulations.

  • Correct terminals โ€” We stock common Faston styles (like F2 0.25โ€ณ) used in Back-UPS battery trays.

Note: If you need a complete drop-in solution (tray/harness/cartridge), order a full RBC35 replacement cartridge instead. This listing is cells only.
