Replacement Battery for HP Omen 15

The KingSener SD03XL is a new lithium-ion laptop battery built to replace the original unit in compatible HP Omen 15 models from 2020. It delivers 11.55V and a rated capacity of 4545mAh or 52.5Wh. The pack uses high-quality cells and a matched PCB to meet the design capacity without shortfall. Physical dimensions match the factory battery for a direct fit.

Suits owners of listed Omen 15 series.

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. Always compare the original battery label and photos before ordering.

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.
