PowerWarehouse 922977-855 8-cell 14.4V 5973mAh laptop battery for HP Omen 17-an 17T-an 16-pin

8-cell 14.4V replacement for HP Omen 17-an

This 8-cell lithium-ion battery delivers 14.4V and 5973mAh capacity for HP Omen 17-an and 17T-an laptops. It matches OEM part numbers 922977-855, FM08, FM08086 and HSTNN-LB7B. The 16-pin connector ensures direct compatibility with the original motherboard socket. Buyers needing a different pin layout or voltage should verify their model first.

Thermals noise and power draw

Lithium-ion chemistry maintains stable voltage across the discharge cycle with minimal self-heating during normal workloads. No moving parts mean completely silent operation inside the chassis. The 5973mAh rating supports typical mixed-use sessions without excessive current draw. Users running sustained heavy loads will see faster depletion but no thermal throttle from the pack itself.

Build quality and connector implications

The 8-cell construction fits the original battery bay without modification or shims. A 16-pin interface aligns with the factory connector for a secure, keyed fit that resists vibration loosening. Cells are housed in a rigid enclosure matching OEM dimensions for latch engagement. Technicians who need a higher cell count or alternate form factor cannot use this unit.
