APC Battery Cells — for APC RBC55 Pack (NOT a Complete Cartridge)
Loose Cells Only  •  AGM (VRLA)  •  18 Ah Class  •  Rebuild/Service Use

These are individual sealed lead-acid AGM (VRLA) batteries — the same cell type used to populate an APC RBC55 battery module. They are not a finished RBC55 cartridge (no tray, wiring, fusing, connectors, or enclosure included).

Use these cells to rebuild your existing RBC55 tray/harness if you wish to perform the replacement yourself, or as service spares for technicians maintaining APC Smart-UPS battery modules.

Important
  • This page is for loose cells only. Customer reuses the original RBC55 tray/harness assembly.
  • Typical RBC55 modules are assembled from four (4) 12 V, 18 Ah cells.
  • Confirm physical fit, terminal style, and harness orientation before ordering (RBC trays can vary).
  • 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.
  • Rebuild-ready support — Ideal when you want to reuse your existing tray/harness rather than buying a full cartridge.

Note: If you need a complete drop-in solution (tray/harness/cartridge), order a full RBC55 replacement cartridge instead. This listing is cells only.
