Replacement battery for HP ProBook 640 645 650 655

This six-cell lithium-ion pack replaces original HP part numbers 718754-001 718755-001 718756-001 718757-001 and CA06. It is built for owners of ProBook 640 G0 G1 645 G0 G1 650 G0 G1 655 G0 G1 models who need a direct-fit replacement. The unit ships new and carries a one-year warranty from the manufacturer.

Smart chip regulates charge and discharge under load

An integrated control chip manages the 10.8 V 4400 mAh cells to provide steadier voltage during extended use rather than only in short bursts. The circuitry includes short-circuit overheat and overload protections that keep output stable when the laptop draws sustained power. Capacity is rated at 48 Wh for consistent runtime across a full work session.

Limited to compatible ProBook models

The battery fits only the listed ProBook 640 645 650 655 series and matches the original 10.8 V specification. It will not work with laptops that require a different voltage or a different physical connector. Buyers who need a higher-capacity pack or a different form factor must look elsewhere.

Questions about this item

Does the 6-cell lithium-ion pack run hot or draw extra power during a full workday?

The 10.8 V 4400 mAh cell chemistry is built to OEM specification with a smart control chip that manages charging and discharge, so heat and power draw stay within normal laptop limits.

What must my ProBook already have for this MPL08273P-20 to fit and charge?

Your laptop must use one of the original part numbers 718754-001, 718755-001, 718756-001 or 718757-001 and accept a 10.8 V 6-cell battery.

Will this replacement work alongside the original charger and BIOS on a ProBook 645 G1?

Yes — the pack matches the 10.8 V 48 Wh rating and includes short-circuit, overheat and overload protections, so it operates with the existing charger and firmware.
