Questions about this item

Does the 11.4V 48Whr 3-cell design run cooler than the original battery during long work sessions?

The lithium-ion cells are tested for stable current and low self-discharge, which helps limit heat build-up during extended use.

Will the battery connect to the existing motherboard connector in my ProBook 650 G4 without an extra cable?

It replaces OEM part numbers CD03XL, 931719-850, 931702-541, HSTNN-IB8B, CD03048XL, 931702-171 and 931702-421, matching the factory connector directly.

Can I keep using my current HP 65W USB-C charger with this battery installed?

The battery charges through the laptop's native charging circuit, so any charger that originally powered the ProBook 640 G4, 645 G4 or 650 G4 will continue to work.
