Replacement Battery for HP 15-bs and 15-bw Series

This new lithium-ion battery replaces original HP part numbers including 919681-221, 919682-121, 919700-850 and 919701-850. It fits HP 15-bs000 and 15-bw000 series laptops such as the 15-bs013dx, 15-bs015dx, 15-bs060wm and 15-bw010nr. The pack uses four cells rated at 14.8V and 2200mAh for 33Wh capacity.

Upgrade from Degraded or Failed Original Pack

The battery restores runtime lost to age, swelling or charge-circuit failure in the factory unit. Built-in overcurrent, overcharge, overdischarge and temperature protection guards the laptop’s charging system. The jump is worth it when the original pack no longer holds a useful charge or triggers a replacement alert in BIOS.

Straightforward Internal Swap with Common Pitfalls

Installation requires removing the bottom case screws, disconnecting the old pack and connecting the new one to the same header. Common issues include forgetting to disable the internal battery in BIOS before opening the chassis, stripping small case screws or pinching the ribbon cable during reassembly. Buyers who need an external charger or a higher-capacity 6-cell alternative cannot use this pack.
