A common issue is failing to seat the connector fully, which can prevent the laptop from recognising the battery or charging correctly.

Verify that your laptop model appears in the supported series: HP Pavilion 15-EG, 15-EH, 15-GW, HP 17-CN, 17-CP, HP 255 G8 or HP 470 G8. Confirm the original battery part number matches one of the listed codes such as HSTNN-DB9Y, HW03XL or L97300-005. Ensure the voltage rating of 11.4V matches the specification on your existing battery.

Questions about this item

How do I confirm the 11.4V 4150mAh Li-polymer battery is working after installation?

The laptop should power on without the AC adapter, show the correct 11.4V voltage in the BIOS or HP Support Assistant, and report a design capacity near 4150mAh; the charge LED should behave normally during charging.

What comes in the box and what must I buy separately?

The box contains the Dr. Battery HW03XL 11.4V 4150mAh Li-polymer battery only; no tools, screws, or AC adapter are included, so have a small Phillips screwdriver ready for the swap.

Which HP part numbers does this HW03XL 11.4V 4150mAh battery replace?

It replaces HP originals HSTNN-DB9Y, HSTNN-IB90, HSTNN-IB9O, HSTNN-LB8U, HSTNN-OB2A, HW03041XL, HW03XL, HWO3XL, L96887-1D1, L96887-2B1, L96887-421, L96887-AC1 and L97300-005.
