This FOCUSTEC HT03XL lithium-polymer battery delivers 41.7Wh at 11.55V across 3 cells. It matches part numbers HT03XL, L11119-855, HT03041XL and the L11421 and HSTNN series codes. The pack fits HP Pavilion 14, 15 and 17 series models including 14-cf, 15-cs, 15-da, 15-db, 15-dy, 17-by and 17-ca lines. It also covers Pavilion x360 14-dh convertible models.

Black polymer casing with included screwdrivers

The black polymer enclosure aligns with the original battery bay on the listed Pavilion chassis. A set of screwdrivers ships in the box so the swap can be done without sourcing tools. No additional cables or adapters are required; the connector matches the motherboard header on compatible units.

Restores runtime on aging original cells

This unit replaces a depleted or swollen factory battery in the compatible Pavilion models above. The upgrade is worth it when the original pack no longer holds a useful charge or shows physical deformation. Buyers needing higher capacity than 41.7Wh or a different voltage should look elsewhere.
