Dr. Battery HW03XL L97300-005 laptop battery

Replacement battery for HP 17-CN

This Dr. Battery Professional Series unit replaces the original HW03XL or L97300-005 pack in compatible HP 17-CN, 17-CP, 255 G8, 470 G8 and Pavilion 15-EG, 15-EH and 15-GW laptops. It uses Li-polymer cells rated at 11.4 V and 4150 mAh to restore mobile power for business and everyday productivity. Built-in protection guards against over-charge, over-discharge, over-heat and short-circuit conditions.

Upgrade from a worn or swollen original pack

The jump is worth it when the factory battery no longer holds a useful charge, shows physical swelling or triggers a capacity-warning alert in the BIOS. OEM-grade cells deliver stable output and long cycle life so the laptop can return to full unplugged runtime. Buyers who need a higher-capacity alternative or a different voltage should look elsewhere because this model matches the original 11.4 V specification exactly.

Straightforward internal swap with basic tools

Installation typically requires removing the bottom case screws, disconnecting the old pack and connecting the new one in the same orientation. The slim 8.0 x 1.5 x 0.8 cm form factor fits the existing bay without modification. Common issues arise if the connector is not fully seated or if the battery calibration cycle is skipped after the first charge, which can cause inaccurate capacity reporting.
