Probook 640 g2

Choose the right probook 640 g2 battery by matching the battery type to your device: CI03 or CI03XL. Then compare capacity (runtime) and confirm compatibility within the ProBook family. The HP batteries in this listing come in a sturdy black plastic shell, and you should select CI03 for standard use or CI03XL if you need longer unplugged hours.

CI03XL offers higher capacity and longer runtime than CI03. In practical use, you’ll experience more hours between charges with XL, while both share the same form factor and connector for easy swapping. Choose XL if you regularly work away from power and want extended unplugged time.

For a student on campus, a standard CI03 battery typically provides sufficient unplugged time. A professional who travels or works away from a power source benefits from the CI03XL’s extended runtime. Both options are HP ProBook batteries designed to fit the same family.

Power off the notebook, unplug it, and insert the CI03/CI03XL battery with proper orientation. Secure the latch, close the housing, and avoid metal contacts. Keep the battery contacts clean and store or charge within safe temperatures, and use genuine HP batteries for best safety and longevity.

Short runtime, failure to charge, or the system not recognizing the battery are clear indicators. Swelling, excessive heat, or physical damage also signal replacement is needed. Replace with a genuine HP CI03/CI03XL battery from this listing to ensure safety and compatibility.

These HP ProBook batteries using the CI03/CI03XL type are designed for ProBook laptops in the same family, not just the 640 g2. Always confirm the connector, voltage, and fit before purchasing. The listing specifies brand HP and the typical black plastic shell for these batteries.
