This Dr. Battery unit replaces the original HP 801554-001, CI03, CI03XL, CIO3, CIO3XL and HSTNN-UB6Q packs. It fits the HP ProBook 640 G2, 645 G2, 650 G2 and 655 G2 models. The lithium polymer cell chemistry matches the factory specification for these notebooks.

Voltage and capacity must match your original

The pack delivers 11.4V and 44Wh at 3900 mAh. Confirm the voltage printed on your old battery before ordering; a mismatch will prevent correct operation. This single electrical profile determines whether the part is suitable for your specific laptop.

Safety protections maintain stable operation

Built-in short-circuit, overheat and overload safeguards protect both the battery and the notebook during charge and discharge cycles. The professional-series cells are selected for consistent service time. A one-year warranty covers manufacturing defects.

Will this battery fit the internal bay of a ProBook 655 G2 without modification?
