  • Advanced AGM technology prevents electrolyte leakage

Direct replacement for UPG UB1222

This 12 V 2.2 Ah sealed lead‑acid battery uses AGM technology to match the original UPG UB1222 specifications. It fits UPS units that require an F1 terminal and a 1222 form factor. The maintenance‑free design means no water checks or electrolyte handling are needed.

Fits existing UPS chassis without modification

The F1 terminals connect directly to the UPS wiring harness, so no adapters or cable changes are required. AGM construction prevents electrolyte leakage in any mounting orientation. Gas recombination exceeds 90 %, reducing internal pressure buildup during float service.

Ready to install with no extra accessories

The battery ships fully charged and sealed, classified as non‑spillable for safe transport. No mounting hardware, cables or software are included because the unit simply replaces the old cell. A three‑year warranty covers UPS and backup applications.
