Replacement Battery for HP ProBook 640 645 650 655
This Dr. Battery MPL08273P-14 unit replaces original HP part numbers 718754-001 through 718757-001 and CA06 series batteries. It fits HP ProBook 640 G0 G1 645 G0 G1 650 G0 G1 and 655 G0 G1 models. The six-cell lithium-ion pack delivers 10.8V and 4400mAh capacity for 48Wh total energy. It is a new component built to OEM specification level with an integrated smart control chip.
Upgrade From Degraded or Failed Original HP Battery
When the factory battery no longer holds a useful charge or shows swelling this replacement restores full runtime. The jump is worth it if the laptop otherwise meets your workload needs and the original part number matches the listed compatibilities. Built-in protections guard against short circuit overheat and overload during charge and discharge cycles. A one-year warranty covers the new pack.
Limits of 10.8V Six-Cell Lithium-Ion Chemistry
Capacity will gradually decline with charge cycles and storage time as is typical for lithium-ion cells. The 4400mAh rating reflects design capacity not a guaranteed runtime figure under every load. This battery does not support higher-voltage or higher-capacity configurations beyond the original specification. Buyers needing longer unplugged time or a different form factor cannot use this pack.

Questions about this item
Will the 6 cell 10.8V pack sit flush in my HP ProBook 655 G1 battery bay?
Yes — the Dr. Battery MPL08273P-14 is built to the same 6 cell 10.8V form factor as the original HSTNN-LB4Y / LB4Z packs used in the ProBook 655 G1.
What is the correct order to seat the pack and engage the release latches?
Slide the battery in until the two side latches click, then press the centre lock until it snaps; the common error is pressing the centre lock first, which prevents the side latches from engaging.
When should I plan to replace the 4400 mAh unit?
Replace the pack when a full charge no longer delivers the rated 48 Wh or the laptop shuts down abruptly under load; the 1 year warranty covers early capacity loss.
