HP 3-Cell 57Wh Replacement Battery

This HP lithium-ion battery supplies 57 watt-hours at 4.93 ampere-hours across three cells. It is built as a direct replacement for compatible HP notebooks that originally shipped with the same capacity. The part arrives new and ready for installation.

Three-cell layout limits runtime on high-drain

A three-cell pack cannot match the endurance of larger six- or nine-cell designs when the processor and GPU sustain heavy loads. Users running continuous compile jobs, video exports or gaming sessions will see noticeably shorter unplugged time compared with higher-capacity alternatives.

Swaps an exhausted or swollen original pack

The battery replaces a factory unit that no longer holds charge or has physically expanded. The jump is worth it when the laptop otherwise meets your needs but tethering to an outlet has become mandatory. It does not add capacity beyond the original specification.
