Dr. Battery MPL08273P-18 6-cell 10.8V 4400mAh

This replacement battery suits HP ProBook 640, 645, 650 and 655 series laptops including G0 and G1 variants. It matches original part numbers such as 718754-001, CA06XL and HSTNN-LB4Y. Buyers needing a different voltage or form factor cannot use this unit.

6-cell lithium-ion capacity and runtime

The pack delivers 4400mAh at 10.8V for 48Wh of energy. Six cells provide enough headroom for typical office workloads and mobile use. Runtime drops under sustained heavy loads or when the cells age beyond their design cycle count.

10.8V lithium-ion interface limits

The battery connects through the ProBook's proprietary multi-pin interface. It supplies a fixed 10.8V output and relies on the laptop's internal charger for current regulation. Systems expecting a different pin-out or voltage will not recognise the pack.

Questions about this item

Will the 10.8V 4400mAh battery fit my HP ProBook 650 G1 alongside the original AC adapter?

Yes, the 6-cell lithium-ion pack replaces part numbers CA06XL, HSTNN-LB4Y and 718754-001 and works with the existing charger.

How do I confirm the 10.8V 4400mAh pack is charging correctly after installation?

The built-in smart control chip enables quicker charging and overload protection; the OS battery meter should show rising capacity within minutes.

Does the box include the 6-cell 10.8V battery only, or are screws and tools also supplied?

The package contains the replacement battery; mounting screws and any opening tools must be sourced separately.
