APC Battery Cells โ€” for APC RBC18 Pack
(NOT a Complete Cartridge)
Loose Cells Only ย โ€ขย  AGM (VRLA) 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
RBC18 battery module.
They are not a finished RBC18 cartridge (no tray, harness, or enclosure included).

Use these cells to rebuild your existing RBC18 tray/harness if you prefer to perform the replacement yourself,
or as service spares for technicians maintaining APC UPS battery modules.

Important
  • This page is for loose cells only. You will reuse your existing RBC18 tray/harness/enclosure.
  • Typical RBC18 modules are assembled from two (2) 6ย V, 7ย Ah cells.
  • Verify dimensions and terminal type before ordering (6ย V blocks vary by case/terminal style).
  • Installation involves battery handling 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 cell sets โ€” When ordered as a pair, cells are matched for balanced charge/discharge performance.
  • Rebuild-ready support โ€” 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 RBC18 replacement cartridge instead.
