Dr. Battery HP 17-CP Replacement
The Dr. Battery Professional Series HW03XL is a new lithium-polymer laptop battery rated at 11.4V and 4150 mAh. It replaces original HP part numbers including HSTNN-DB9Y, HW03XL, and L97300-005. Designed for HP Pavilion, 255 G8, 470 G8, and 17 Series notebooks, it restores mobile power for professional and everyday productivity use.
Suits HP 17-CN and 17-CP owners
This unit fits models such as the HP 17-CN0003DX, 17-CP1035cl, and 17-CP3035cl, plus related Pavilion 15-EG and 15-EH configurations. Buyers needing a higher capacity than 4150 mAh or a different voltage should look elsewhere. It is not compatible with laptops outside the listed HP series or part-number cross-reference.
Straightforward internal swap
Installation requires opening the chassis, disconnecting the old pack, and connecting the new battery to the same motherboard header. The 8.0x1.5x0.8 cm form factor matches the original bay. Common issues include forgetting to detach the bottom cover screws or failing to seat the connector fully, which prevents the system from recognising the replacement.

Questions about this item
Does my HP 17-CP series laptop need a specific connector for the HW03XL battery?
The HW03XL uses the same connector as the original HP batteries it replaces, so it fits HP 17-CP, 17-CN, Pavilion 15-EG, 15-EH, 15-GW, 255 G8, and 470 G8 models directly.
Will the 11.4V 4150 mAh Dr. Battery work if I keep my original HP AC adapter?
Yes, the replacement battery charges normally with the original HP adapter because it matches the 11.4V voltage and Li-polymer chemistry of the factory pack.
How can I confirm the new battery is recognised after I install it?
The BIOS and Windows will show the correct 11.4V design voltage and 4150 mAh capacity, and the battery icon will report charging and discharging without error codes.
