Direct replacement for HP Pavilion

This 11.34 V lithium-ion battery delivers 41.04 Wh and 3440 mAh, matching the original HW03XL specification. It fits HP Pavilion 15-EG, 15-EH, 17-CN and 17-CP series laptops as well as select 240, 245, 250, 255 and 470 G8 or G9 units. The pack replaces part numbers including HSTNN-IB90, L96887-1D1 and L97300-005. Installation tools are included in the package.

Built-in tools simplify the swap

The bundled toolkit lets you open the chassis and disconnect the old pack without sourcing separate drivers. A snug connector fit ensures the battery is recognised on first boot; if detection fails, reseat the cable and complete three to four full charge cycles down to five percent to calibrate the new cells. Li-ion chemistry requires no special maintenance beyond normal use.

Restores runtime on ageing original packs

Owners of the listed HP models whose factory battery no longer holds a useful charge will regain full mobility. The capacity matches the OEM 41.04 Wh rating, so daily unplugged time returns to as-new levels. Buyers needing a higher-capacity extended pack or a different voltage should look elsewhere, as this unit replicates the stock specification exactly.
