HP Pavilion x360 14-ba series replacement

This 41.7Wh lithium-polymer battery operates at 11.55V across three cells. It matches part numbers BK03XL, 916811-855, 916812-855 and HSTNN-LB7S for the Pavilion x360 convertible 14-ba and 14m-ba families. The pack is supplied new in black with two screwdrivers included.

Built-in protection circuits and tool kit

Overcharge, overdischarge, over-temperature and short-circuit safeguards are integrated into the pack. The bundled screwdrivers let you open the chassis and swap the battery without sourcing separate tools. No additional mounting hardware or cables are required beyond what the laptop already uses.

Restores runtime on aging 14-ba units

Replaces an original cell that no longer holds charge through a full work session. The 500-cycle design life suits daily mobile use where the laptop is unplugged for several hours at a time. Buyers whose machine needs a higher-capacity pack or a different voltage should look elsewhere.
