Please note that HP manufactured two different variations of the EO04XL battery connection interface. One version is equipped with a black connector plug, while the alternative version utilizes a white connector plug. These interface versions are not interchangeable. Before placing your order, you must unscrew your notebook's lower backplate to physically inspect the cable connector color on your stock factory battery to guarantee an exact electrical match.
