Who This Suits

Owners of listed HP 14S-FQ, 17-CN, 17-CP, 17-CH, Pavilion 15-EG, 15-EH, 15-GW, 255 G8, 255 G9, 240 G9, 245 G9, 250 G9 and 470 G8 models who need a direct replacement for original part numbers such as HSTNN-IB90, HW03XL, L96887-421 or L97300-005. Buyers whose laptop requires a different voltage, connector layout or form factor should verify compatibility before ordering.

Installation Notes

The battery fits into the standard internal compartment of the compatible HP chassis and connects via the original cable. No soldering or firmware update is required. Common issues include failing to seat the connector fully, which prevents charging, and not calibrating the new pack through a full charge and discharge cycle, which can cause inaccurate capacity reporting.

Questions about this item

Does this 11.4V 4150mAh Li-polymer battery fit my HP 255 G8 laptop?

Yes, it is compatible with HP 255 G8 series laptops and replaces original part numbers such as HW03XL and L97300-005.

Will the 8.0x1.5x0.8 cm dimensions match the bay on my older HP Pavilion 15-EG?

The battery is built to the same form factor as the original HSTNN-IB90 so it seats correctly in supported Pavilion 15-EG models.

How can I confirm the battery is delivering stable output after I install it?

Check that the laptop recognises the 11.4V rating in the BIOS power section and that the charge cycle completes without overheating or error alerts.
