Replacement battery for HP Omen 17-an series

This lithium-ion unit replaces part numbers FM08, HSTNN-LB8A and HSTNN-LB8B across the Omen 17-an range. It delivers 14.4 volts and 83.22 watt-hours of capacity in a black housing. The pack is supplied new and carries a twelve-month warranty from the supplier. Owners of compatible 17.3-inch models can restore original run time with a direct swap.

Sustained discharge at 14.4V with 86Wh peak rating

The cell chemistry maintains the rated voltage through typical workloads rather than only in short bursts. The 83.22Wh nominal capacity supports extended sessions away from mains power. Thermal behaviour follows standard lithium-ion limits for internal laptop bays. No additional cooling or firmware changes are required for normal operation.

Verify your exact model number before ordering

The compatibility list covers many Omen 17-an variants but not every 17-inch HP chassis. Check the label on your original battery for part numbers such as 922752-421 or TPN-Q195. Machines outside the documented series, including newer Omen generations or Pavilion models, will not fit this pack. Ensure the connector orientation matches the bay layout.

Questions about this item

Does the FM08 14.4V battery generate noticeable heat or noise during extended use?

The FM08 is a lithium-ion battery with no moving parts, so it produces no audible noise. Under normal load it warms slightly, which is typical for a 83.22Wh pack, but it does not require active cooling.

What must I already own for this FM08 battery to work in my laptop?

You need a compatible HP Omen 17-an series chassis that accepts part numbers HSTNN-LB8A or HSTNN-LB8B, plus the original battery connector and mounting points already present in those models.

Will the FM08 83.22Wh pack fit and charge correctly in an Omen 17-an013tx that originally used a 922752-421 battery?

Yes. The FM08 replaces part number 922752-421 directly, matches the 14.4V/14.6V voltage and 83.22Wh capacity, and uses the same form factor for the listed Omen 17-an models.
