Fits directly into the existing battery bay

The battery slides into the standard compartment on the listed ProBook chassis and connects to the motherboard using the original connector. No tools or firmware updates are required and the unit frees the user from carrying a power brick during meetings or travel. Built-in circuit protection guards against overcharge over-discharge and short circuits.

Maintains steady output during extended work

The lithium-ion chemistry delivers consistent voltage across the discharge curve so performance does not drop as the charge depletes. CE RoHS and FCC certification confirms compliance with safety and environmental standards. Buyers needing higher capacity than 5200mAh or compatibility with newer ProBook generations should verify part numbers before purchase.

Questions about this item

How long will the 5200mAh capacity last before the voltage drops under continuous load?

The 6-cell 10.8V 5200mAh Li-ion pack delivers its rated capacity until the built-in protection circuit stops discharge at the safe lower voltage limit.

Does the battery get hot or draw extra power during all-day use in an HP ProBook 640 G1?

Normal operation stays within the 10.8V design envelope; the integrated protection circuit prevents excessive current draw and limits temperature rise.

Which HP part numbers must match for this CA06XL to fit my laptop?

It replaces HP part numbers 718677-421, 718678-421, 718755-001, 718756-001, HSTNN-DB4Y, HSTNN-LB4X, HSTNN-LB4Y, HSTNN-LB4Z and HSTNN-LP4Z.
