APC Battery Cells โ€” for APC RBC50 Pack (NOT a Complete Cartridge)
Loose Cells Only โ€ข AGM (VRLA) โ€ข 18 Ah Class โ€ข Rebuild/Service Use

These are individual sealed lead-acid AGM (VRLA) batteries โ€” the same cell type used to populate an APC RBC50 battery module. They are not a finished RBC50 cartridge (no tray, wiring, fusing, connectors, or enclosure included).

Use these cells to rebuild your existing RBC50 tray/harness if you wish to perform the replacement yourself, or as service spares for technicians maintaining APC Smart-UPS / Back-UPS Pro battery modules.

Important
  • This page is for loose cells only. Customer reuses the original RBC50 tray/harness assembly.
  • Typical RBC50 modules are assembled from two (2) 12ย V, 18ย Ah cells.
  • Verify terminal style before ordering (commonly nut & bolt / T3 / FP style on higher-capacity blocks).
  • Battery handling required โ€” follow UPS/battery safety procedures and local disposal regulations.

Why buy from Gruber
  • Always-fresh inventory โ€” High turnover helps ensure recent-date cells for maximum service life.
  • Matched pair sets โ€” When ordered as a pair, cells are matched for balanced charge/discharge performance.
  • Terminal-fit awareness โ€” We stock common nut & bolt styles used in Smart-UPS trays; confirm your harness hardware before ordering.

Note: If you need a complete drop-in solution (tray/harness/cartridge), order a full RBC50 replacement cartridge instead. This listing is cells only.
