52.5 Wh LK03XL replacement battery

The POWER-FENG LK03XL is a new lithium-polymer battery rated at 52.5 Wh and 11.55 V. It replaces multiple HP part numbers including LK03XL, HSTNN-LB7U and 916814-855. Designed for owners of HP Envy x360 15-bp and 15-CN series laptops who need a direct replacement for a worn or failed original pack.

Interface and fit constraints

This pack uses the proprietary connector and form factor defined by HP for the listed TPN-W127 through TPN-W137 platform codes. It will not fit laptops outside the Envy x360 15-bp0xx, 15-bp1xx, 15-CN0xxx or 15-CN1xxx model ranges. Buyers who need a battery for a different HP series or a non-HP device cannot use this part.

Capacity and voltage match

The single specification that decides compatibility is the 52.5 Wh capacity combined with the 11.55 V nominal voltage. Only systems engineered for this exact energy and voltage rating will charge and report capacity correctly. If your service manual specifies a different watt-hour or voltage value, this battery is not the correct part.
