Replacement Battery for HP ProBook 640 645 650 655

This 5200mAh 10.8V lithium-ion pack is built for HP ProBook 640, 640 G1, 645, 645 G1, 650, 650 G1, 655 and 655 G1 notebooks. It arrives new from the manufacturer with UL, CE, FCC and RoHS certifications. Grade A cells and integrated circuit protection guard against short circuits, overheating and overloads. The six-cell design targets around two hours of runtime under typical use.

Capacity and Voltage Match

The single specification that decides fit is the 5200mAh capacity at 10.8V across six cells. Your original battery must show the same voltage and a comparable milliampere-hour rating; a different voltage will prevent the notebook from charging or powering on. Matching the listed part numbers such as CA06XL, CA06, 718756-001 or 718757-001 confirms electrical compatibility.

Installation and Service Life

The pack slots directly into the ProBook battery bay without tools or cables, freeing the AC adapter for desk use while you work untethered. Built-in protection circuits keep the system stable during charge and discharge cycles. The cells are rated for up to 500 recharge cycles, so the battery can serve through multiple years of daily charging. Buyers who need longer unplugged runtime or a higher-capacity extended pack will not be served by this standard six-cell unit.
