Replacement Battery for HP ProBook G2

The NShi CI03XL is a new lithium-ion battery rated at 11.4V and 48Wh. It replaces part numbers CI03XL, HSTNN-UB6Q and 801554-001. Designed for HP ProBook 640, 645, 650 and 655 G2 models, it restores mobile power for everyday work.

Who This Suits and Who It Does Not

This battery suits owners of the listed ProBook G2 laptops who need a direct voltage and capacity match. It does not suit users whose devices require a different voltage, a different capacity, or a different physical connector. Buyers with other HP series or other generations should verify their original part number first.

Deciding Specification

The single specification that decides fit is the 11.4V 48Wh rating combined with the CI03XL part number. Only laptops that originally shipped with this exact voltage, capacity and part number will accept the battery without modification.

Questions about this item

Does this 11.4 V 48 Wh battery fit my HP ProBook 640 G2 without any other parts?

Yes, it is a direct replacement for the original CI03XL and HSTNN-UB6Q batteries used in the ProBook 640 645 650 655 G2 series, so no additional components are required.

Will the battery charge correctly with the original AC adapter I already use for my ProBook 650 G2?

The cell voltage and capacity match the factory specification, so the existing charger will charge it normally without any firmware or hardware changes.

How can I confirm the battery is recognised and holding charge after the first 24-hour conditioning charge?

The operating system should report the correct 48 Wh design capacity, show a charging icon when plugged in, and deliver run-time consistent with a healthy 11.4 V pack.
