Dr. Battery MPL08273P-19 6-cell 10.8V 4400mAh laptop battery

Replacement for HP ProBook 640 645 650 655 series

This 6-cell lithium-ion battery delivers 10.8V and 4400mAh capacity for compatible HP ProBook models including the 640, 645, 650 and 655 series across G0 and G1 generations. It replaces original part numbers such as 718754-001, 718755-001, 718756-001, 718757-001, CA06, CA06XL, CA09 and HSTNN-DB4Y. The pack is designed for owners who need a direct swap without modification.

Built-in smart control chip with protection circuits

The integrated chip manages quicker charging, lower power consumption and longer discharge time while providing short-circuit, overheat and overload safeguards. These protections operate automatically during daily use and require no additional software or driver installation. The cell chemistry and circuitry are calibrated to meet OEM specification levels for reliable operation.

Lithium-ion chemistry and 10.8V fixed voltage

The 48Wh pack uses standard lithium-ion cells that degrade with charge cycles and storage time, so runtime will gradually decrease. The fixed 10.8V output only suits laptops designed for this exact voltage; systems requiring a different voltage cannot use this battery. Buyers who need higher capacity or a different form factor should verify their original part number before ordering.
