Battery capacity in watt-hours (Wh) determines how long your ProBook runs between charges. With 11.55V and 45Wh, the RE03XL offers longer runtime than lower-capacity replacements, though actual life depends on how you use the laptop. Higher Wh can mean a slightly larger battery, so verify the fit and connectors to avoid clearance issues. Always choose an original genuine HP battery to ensure the stated Wh is delivered.
