Suitable for owners of listed HP ProBook models

Buyers with laptops outside the 640 645 650 655 G0 G1 range should look elsewhere as fit and connector alignment are not guaranteed. The pack is designed for the specific voltage and form factor of those series only. Users requiring higher capacity or a different chemistry will need another solution.

10.8 V 4400 mAh lithium-ion specification

This voltage and capacity pair determines whether the battery matches the original electrical profile of the supported HP ProBook models. Confirm the original battery label shows 10.8 V and a compatible part number before ordering. The 48 Wh energy rating reflects the same nominal capacity. A one-year warranty backs the replacement.

Questions about this item

Which HP ProBook models does this DRPROHP273P-01 battery fit?

It replaces original HP batteries CA06, CA06XL, CA09, HSTNN-DB4Y, HSTNN-LB4X, HSTNN-LB4Y and HSTNN-LB4Z in ProBook 640, 645, 650 and 655 G0 and G1 series laptops.

What runtime does the 4400 mAh / 48 Wh rating give in daily use?

The 48 Wh capacity restores the original run time for compatible ProBook 640, 645, 650 and 655 models; actual hours depend on screen brightness, workload and power settings.

How does the 10.8 V lithium-ion pack connect to the laptop?

It uses the same proprietary HP connector as the original CA06/CA06XL batteries, so it slots directly into the ProBook battery bay without adapters.
