11.4 V 4150 mAh Li-polymer replacement

This Dr. Battery HW03XL unit is a new lithium-polymer replacement battery rated at 11.4 V and 4150 mAh. It is built for HP Pavilion 15-EG, 15-EH and 15-GW models as well as HP 255 G8, 470 G8 and 17-CN/CP series notebooks. The pack uses OEM-grade cells and includes protection against over-charge, over-discharge, overheat and short-circuit conditions. It targets professionals and everyday users who need dependable runtime without replacing the whole laptop.

Replaces HSTNN-DB9Y HSTNN-IB90 HW03XL originals

The battery replaces HP original part numbers including HSTNN-DB9Y, HSTNN-IB90, HSTNN-LB8U, HSTNN-OB2A, HW03041XL, HW03XL, L96887-1D1, L96887-2B1, L96887-421, L96887-AC1 and L97300-005. The upgrade is worth it when the original pack no longer holds a useful charge or shuts down under load. It restores factory-level voltage and capacity for the supported HP 14S-FQ, 17-CH, 17-CN and Pavilion 15 series. Buyers needing a higher-capacity pack or a different voltage should look elsewhere.

Internal fit with screw access and cable care

Installation requires opening the laptop chassis, removing the old pack and connecting the new battery cable to the motherboard header. Most HP 15 and 17 models use internal screws and a bottom cover that must be lifted carefully. The main risk is damaging the fragile connector or pinching the cable during reassembly. Users uncomfortable with disassembly should seek professional fitting. No external tools or adapters are included.

Questions about this item

Will the 8.0 x 1.5 x 0.8 cm battery fit inside my HP Pavilion 15-EG series chassis without modification?

The pack measures 8.0 by 1.5 by 0.8 centimetres and weighs 0.4 kg, matching the original HW03XL form factor so it seats in the standard battery bay of the listed Pavilion 15-EG, 17-CN, 255 G8 and 470 G8 models.

What is the correct way to install the HW03XL battery, and which step do people often miss?

Power off the laptop, disconnect the AC adapter, remove the bottom case screws, detach the old battery connector from the motherboard, fit the new 11.4 V 4150 mAh pack, reconnect the cable firmly, replace the cover and screws, then charge fully before first use — the step most often skipped is that initial full charge.

How long will the Li-polymer cells in this 11.4 V 4150 mAh pack last before I need a replacement?

Li-polymer chemistry typically delivers several hundred full charge cycles; when runtime drops noticeably or the laptop shuts down unexpectedly, replace the battery with another HW03XL-compatible unit.
