Replacement battery for HP ProBook series
This 6-cell lithium-ion pack replaces original HP part numbers 718754-001 through 718757-001 and CA06 variants. It fits ProBook 640, 645, 650 and 655 models including G0 and G1 revisions. The unit ships new and carries a one-year manufacturer warranty.
Sustained discharge with smart-chip management
An integrated control chip regulates charge current to reduce heat during extended use and prevents short-circuit, overheat and overload conditions. The 48 Wh capacity delivers consistent voltage across the discharge cycle rather than a brief peak. Cell balancing helps maintain runtime over repeated cycles.
10.8 V lithium-ion interface limits
The pack operates at a fixed 10.8 V and cannot be used in laptops that require a different voltage or cell count. Capacity is set at 4400 mAh, so runtime scales directly with the host system's power draw. Physical dimensions match the original HSTNN-LB4Y and HSTNN-LB4Z form factor only.

Questions about this item
How much heat does the 10.8V 4400mAh pack generate during a full day of use?
The lithium-ion cells run at normal operating temperature; the built-in smart chip manages charge cycles to limit excess heat.
Which original HP part numbers must my ProBook already use for this replacement to fit?
It replaces HP part numbers 718754-001, 718755-001, 718756-001 and 718757-001.
Will the 6-cell 48Wh unit work in an older ProBook 640 G0 that currently holds a 9-cell battery?
Yes, it is listed for the 640 G0; the laptop will recognise the lower capacity and report shorter runtime.
