HP Pavilion Compatible Battery

This 41.04Wh lithium-polymer battery replaces the HW03XL pack in HP Pavilion 15-EG, 15-EH and 17-CN series notebooks. It delivers 11.34V from three cells and includes two auxiliary installation tools for a straightforward swap. The pack is new and ready for immediate use.

20V Adapter Interface Limit

The battery charges from a 20V AC adapter, so it cannot be used with chargers that only supply lower voltages. Systems expecting a different cell count or voltage will not recognise the pack correctly. Buyers who need a higher capacity or a different voltage should look elsewhere.

Polymer Build With Tool Kit

The black polymer enclosure weighs 0.53 pounds and fits the existing battery bay without modification. Built-in protection guards against overcharging, overheating and short-circuiting during daily cycles. The included tools simplify removal of the old unit and securing the new one.
