POWER-FENG 83Wh 11.58V WK06XL laptop battery

Battery identity and target laptops

This is a new 83Wh lithium-polymer replacement battery rated at 11.58V and 6880mAh. It matches part numbers WK06XL, HSTNN-WB0C, M41640-CD1 and M41711-005. It fits HP OMEN 16-B, 16-K and 16-N series plus OMEN 17-CK series models such as 17-ck0024ur, 17-ck0020nr and 17-ck0019u. Buyers whose laptops use a different voltage or connector cannot use this pack.

Sustained load behaviour

The 83Wh capacity is designed to deliver the rated 11.58V steadily during long sessions rather than only in short bursts. Lithium-polymer chemistry helps the cell maintain voltage under continuous draw from high-performance CPUs and GPUs. Runtime will vary with workload, screen brightness and power-management settings. The pack is not intended for laptops that require a higher voltage or a different cell configuration.

Installation notes and common issues

Installation requires opening the chassis, disconnecting the old pack and connecting the new one to the same motherboard header. Screws are often small and easily stripped, so the correct driver size matters. A frequent issue is the battery not being recognised until the BIOS is updated or the system is power-cycled. Another common problem occurs when the replacement is forced into a model that shares the chassis but uses a different pin-out.
