This unit fits HP Omen 15 2020 models including the 15-ek0000 and 15-en0000 series when the original part number is HSTNN-OB1R, L84357-AC1 or L84394-005. Buyers with different part numbers or other laptop families should look elsewhere because the connector and case profile will not match.

52.5Wh capacity for daily workloads

A full charge stores 52.5Wh, providing several hours of typical office or web use on a healthy platform. Runtime falls under heavy GPU loads, high screen brightness or hot environments. The supplier recommends two or three full charge and discharge cycles at low current to settle the cells. Avoid leaving the AC adapter connected continuously and store above 80% charge if unused for a month.
