This 51Wh lithium-polymer replacement fits HP ProBook 640 G2, 640 G3, 645 G2, 645 G3, 650 G2, 650 G3, 655 G2 and 655 G3 notebooks. It ships new and matches the original CI03XL, CI03 and HSTNN part numbers listed by the manufacturer. The three-cell pack delivers 11.4 volts for direct compatibility.

51Wh Capacity Defines Runtime

The 51 watt-hour rating is the single figure that determines whether this unit matches the factory runtime of your ProBook. A lower-capacity pack would shorten battery life; a higher-capacity pack would require a different physical chassis. This unit sits at the exact 51Wh specification.

Built-In Protection Circuits

Overcurrent, overcharge, overdischarge, over-temperature and short-circuit safeguards are integrated on the cell board. These circuits protect both the battery and the notebook during daily charge cycles. The supplier rates the pack for up to 500 recharge cycles over its service life.

Which connector standard does the CI03XL use and what does it limit?

What physical space is needed to fit this 3-cell pack in a ProBook 650 G2?

The 3-cell Li-Polymer pack is shaped to the original CI03XL form factor, so it slides into the standard battery bay of ProBook 640, 645, 650 and 655 G2 and G3 chassis without modification.
