Under continuous load the cell delivers its rated 18 Ah capacity at a steady rate rather than a short burst. The 15 kg weight reflects the lead-acid construction that maintains voltage stability throughout extended runtime periods.

Questions about this item

How much heat does the 12 V 18 Ah battery generate during continuous all-day operation?

The sealed lead-acid design produces minimal heat under normal float charge; ensure the UPS cabinet has adequate ventilation so internal temperatures stay within the manufacturer's specified range.

Which connectors or cables must I already have to install the 1218HRNB unit in my UPS?

The battery uses the standard F2 faston terminals found on the APC CP50B48; reuse the existing harness from your UPS or obtain a matching F2 cable set if the original leads are damaged.
