Compatible HP Omen Models

This 15.4V lithium-ion battery replaces the original unit in HP Omen 15-dc0051nr 15-dc0020nr 15-dc1088nr 15-cb041nr 15-cx0056wm notebooks. It uses a four-cell layout rated at 70W to restore mobile runtime. The pack is new and carries CE and RoHS certification for safety compliance.

Sustained Discharge Behaviour

Premium cells are engineered to maintain a stable voltage curve during extended sessions such as video playback or document work. The chemistry resists rapid fade so the laptop can run longer on a single charge without sudden shutdowns. Consistent output helps the system avoid throttling when the pack is under continuous load.

Pre-Installation Checklist

Verify the exact model number printed on the base of your Omen matches one of the five listed part numbers before ordering. Confirm the existing battery shows 15.4V on its label to ensure voltage alignment. Ensure the chassis bay accepts a four-cell form factor and that the connector orientation matches the original. Buyers needing a higher-wattage pack or a different cell count should look elsewhere.

The 15.4V 70W lithium-ion pack runs cool under normal load; its four premium cells are designed for steady output without excess heat during extended sessions.

What must my HP Omen laptop already have for this 4-cell 15.4V replacement to fit and work?

Your Omen must be one of the listed models — 15-dc0051nr, 15-dc0020nr, 15-dc1088nr, 15-cb041nr or 15-cx0056wm — so the battery connector and chassis match exactly.

Will this 15.4V 70W battery charge and run properly alongside the original AC adapter I keep from my older Omen?

Yes, the replacement is 100% compatible with the specified Omen models and works with the original 15.4V adapter without any changes to charging behaviour.
