Replacement battery for HP 15-bs and 15-bw series

This 31WH lithium-ion battery replaces part numbers 919700-850, 919701-850 and JC03. It fits HP 15-bs0xx, 15-bs1xx and 15-bw0xx models including 15-bs015dx, 15-bs113dx and 14-bw010nr. The cell chemistry matches the original specification for direct installation. Owners of these notebooks can restore mobile runtime without adapter dependency.

Upgrade from depleted or failing original cells

The unit replaces batteries that no longer hold charge or report capacity errors. Swapping is worthwhile when runtime drops below useful levels or the system throttles due to voltage sag. It also covers replacements for part numbers 919681-221, 919682-121, 919682-421 and 919682-831. Users with physically swollen packs should prioritise immediate replacement.

Steady output during extended unplugged sessions

Lithium-ion chemistry delivers consistent voltage across the discharge curve rather than a sharp drop-off. The 31WH capacity supports typical office workloads for multiple hours per cycle. Thermal behaviour remains stable under continuous draw because the pack uses the same form factor as the factory unit. No performance cliff appears late in the cycle.
