Replacement Battery for HP ProBook 640 645 650 655

This new lithium-ion battery replaces part numbers CA06 CA06XL and HSTNN-LB4Y among others. It fits HP ProBook 640 645 650 655 G0 and G1 models. The pack contains six cells rated at 5200mAh and 11.1V. It is built with overcharge overdischarge over-temperature and short-circuit protection.

Capacity Limits and Cycle Life

The 5200mAh capacity sets the runtime ceiling for a single charge. The manufacturer rates the pack for up to 500 recharge cycles over its service life. After that point capacity will decline and runtimes will shorten. The protection circuits stop charging or discharging if voltage or temperature move outside safe limits.

Verify Model and Part Number Before Ordering

Check the label on your existing battery for the exact HP spare number such as 718677-421 718678-421 or HSTNN-LB4Y. Confirm your laptop model matches the supported ProBook 640 645 650 655 G0 G1 list. Ensure the voltage printed on the old pack reads 11.1V. This battery will not fit other HP series or different voltage variants.

Questions about this item

Which capacity and voltage version should I choose for my HP ProBook 650 G1?

The CA06XL is a single 5200mAh 11.1V 6-cell lithium-ion pack that replaces the listed HP spare numbers and fits the ProBook 640, 645, 650 and 655 G0 and G1 models.

What does the 5200mAh 11.1V rating mean for daily runtime on a ProBook 645 G1?

The 5200mAh 11.1V rating sets the total energy the pack can store; actual runtime depends on screen brightness, workload and power settings, but the battery is built to meet OEM capacity targets for these ProBook models.

What interface does this battery use and what does it limit in practice?

It connects through the standard ProBook 640/645/650/655 battery bay connector, so the laptop's charging circuit governs charge rate and the firmware enforces the 500-cycle design life and built-in overcharge, overdischarge, over-temperature and short-circuit protections.
