What this battery replaces

This Dr. Battery MPL08273P-22 is a new six-cell lithium-ion pack rated at 10.8 V and 4400 mAh. It serves as a direct replacement for original HP part numbers including 718754-001, 718755-001, 718756-001, 718757-001, CA06, CA06XL, CA09, HSTNN-DB4Y and HSTNN-LB4X. The pack stores 48 Wh and carries a one-year manufacturer warranty.

Who it suits and who it does not

It fits HP ProBook 640, 640 G0, 640 G1, 645, 645 G0, 645 G1, 650, 650 G0, 650 G1, 655, 655 G0 and 655 G1 models. Buyers whose laptop requires a different voltage, cell count or physical shape should look elsewhere. Owners of other HP series or non-HP notebooks cannot use this pack.

The specification that decides fit

The 10.8 V output and 4400 mAh capacity must match the original battery label exactly; a mismatch means the battery will not work safely in the machine. Verify the part number on the old battery before ordering.

Questions about this item

How long does the one-year warranty on this 10.8 V, 4400 mAh pack last before I need a replacement?

The manufacturer provides a one-year warranty on the 6-cell lithium-ion unit; after that period you would purchase a new pack if capacity has fallen below your needs.

What limits runtime first when the battery powers a ProBook 650 G1 continuously?

The 48 Wh capacity determines how long the laptop runs before the pack must be recharged; sustained load drains the 4400 mAh cells until the low-voltage cutoff engages.

Does the pack get hot or noisy during all-day use in a 640 G0?

The battery has no moving parts, so it produces no noise; warmth is normal during discharge, and the built-in smart chip manages over-heat protection to keep temperatures within safe limits.
