Replacement battery for HP ProBook 640 G1 and 645 G1

This Dr. Battery unit is a new six-cell lithium-ion pack rated at 10.8 V and 4400 mAh. It replaces original HP part numbers 718754-001, 718755-001, 718756-001 and 718757-001. The pack fits ProBook 640, 645, 650 and 655 series laptops including G0 and G1 generations.

Steady discharge with built-in protection chip

The integrated smart control chip manages charge cycles for lower power draw and longer run time per session. It enforces short-circuit, overheat and overload safeguards so the pack delivers consistent voltage under continuous load rather than only in brief bursts.

Verify model and original part number first

Check your laptop's exact model suffix and the sticker on the old battery against the compatibility list above. The pack is not suitable for ProBook models outside the 640, 645, 650 and 655 families or for units requiring a different voltage or cell count.

Questions about this item

Does the 6-cell 4400 mAh pack run hotter or draw more power than the original 48 Wh HP battery during long sessions?

It matches the original 10.8 V 48 Wh specification, so thermal output and power draw are the same as the factory unit.

My ProBook 650 G1 charges via a barrel connector — is anything else required to use this 10.8 V pack?

No extra parts are needed; the battery slides into the existing bay and connects directly to the laptop's internal connector.

Will the smart control chip in this Dr. Battery unit communicate correctly with the firmware on my older ProBook 640 G0?

Yes, the built-in protection chip is designed to work with the charging logic of all listed ProBook 640, 645, 650 and 655 models.
