What this battery replaces

This HW03XL lithium-ion battery is a direct replacement for HP Pavilion 15-EG, 15-EH, 17-CN and 17-CP series notebooks. It also fits HP 240 G9, 245 G9, 250 G9, 255 G8, 255 G9 and 470 G8 models. The pack delivers 11.34V and 41.04Wh capacity. Buyers needing a higher-wattage pack or a different form factor cannot use this unit.

Check your current battery before ordering

Open the laptop and locate the original battery part number on the label. Match it against the compatible list: HW03XL, HSTNN-IB90, HSTNN-LB8U, HSTNN-OB2A, L96887-1D1, L96887-421, L96887-AC1 or L97300-005. Verify the connector position and cable length match the product image. If the label is missing or unreadable, do not guess — contact support with your laptop serial number.

Installing and settling the new pack

The battery ships with installation tools for the rear cover screws. After fitting, ensure the interface seats fully; a loose connection will prevent detection. Run the pack down to five percent, then charge to full and repeat three to four cycles to calibrate the fuel gauge. This unit is not compatible with laptops outside the listed HP series or with AC adapters requiring a different voltage.

Questions about this item

Does the HW03XL battery arrive with the screwdrivers and pry tools needed to open my HP Pavilion 15-EG?

The manufacturer highlights state that the package also comes with installation tools, so the necessary screwdrivers and pry tools are included.

My original battery is marked 41.04 Wh — is the HW03XL the correct capacity match?

Yes, the HW03XL is rated at 11.34 V and 41.04 Wh (3440 mAh), matching the capacity printed on your original battery.

After fitting the HW03XL, what does the 41.04 Wh rating actually deliver in daily use on a Pavilion 15-EH?

The 41.04 Wh rating reflects the energy the pack stores; real-world runtime depends on screen brightness, workload and power settings, but the manufacturer advises running the new pack down to 5 % then completing three to four full charge cycles to reach its rated capacity.
