APC Battery Cells — for APC RBC57 Pack (NOT a Complete Cartridge)
Loose Cells Only  •  AGM (VRLA)  •  F2 Faston  •  Rebuild/Service Use

These are individual sealed lead-acid AGM (VRLA) batteries — the same cell type used to populate an APC RBC57 battery module. They are not a finished RBC57 cartridge (no tray, wiring, fusing, connectors, or enclosure included).

Use these cells to rebuild your existing RBC57 tray/harness if you wish to perform the replacement yourself, or as service spares for technicians maintaining APC SURTA battery modules and external battery packs.

Important
  • This page is for loose cells only. Customer reuses the original RBC57 tray/harness assembly.
  • Typical RBC57 modules are assembled from four (4) 12 V, 9 Ah cells.
  • Verify terminal type before ordering (Faston tabs, commonly F2 style).
  • Battery handling required — follow UPS/battery safety procedures and local disposal regulations.

Why buy from Gruber
  • Always-fresh inventory — High turnover helps ensure recent-date cells for maximum service life.
  • Matched 4-cell sets — When ordered as a set, cells are matched for balanced charge/discharge performance.
  • Terminal-fit awareness — We stock common Faston tab styles; confirm your harness leads match F2 before ordering.

Note: If you need a complete drop-in solution (tray/harness/cartridge), order a full RBC57 replacement cartridge instead. This listing is cells only.
