Replacement Battery for HP ProBook 640 645 650

This 48Wh lithium-ion battery replaces the original CD03XL pack in HP ProBook 640, 645 and 650 G4, G5 and G7 models. It operates at 11.4V using four cells and fits part numbers including HSTNN-LB8F, HSTNN-IB8B, HSTNN-UB7K and 931702-421. The pack is supplied new with two screwdrivers and an instruction sheet for installation. It is not for users whose laptop requires a different voltage or connector layout.

Sustained Runtime on a Single Charge

The manufacturer rates typical use at three to six hours depending on workload and screen brightness. Under continuous load the four-cell design will discharge steadily until the pack reaches its low-voltage cutoff. Capacity is stated as 4212mAh at 11.4V, so runtime scales directly with the power draw of the specific ProBook configuration. It is not for buyers who need all-day operation without recharging.

Build Quality and Daily Handling

The black casing matches the original chassis colour and meets UL, CE, FCC and RoHS safety certifications. Two screwdrivers are included so the bottom cover can be removed and refitted without sourcing tools separately. The instruction sheet illustrates the connector alignment and screw sequence for a secure fit. It is not for technicians who prefer a battery with a built-in fuel gauge or hot-swap capability.

Questions about this item

Does the 48Wh 11.4V lithium-ion pack run hot or draw extra power during all-day use?

The cell chemistry is standard Li-ion at 11.4 V and 48 Wh; it behaves like the original HP pack and does not add heat or power draw beyond normal operation.

What must I already own to install this CD03XL battery?

You need a compatible HP ProBook 640, 645 or 650 G4, G5 or G7 chassis and a small Phillips screwdriver; the package includes two screwdrivers and an instruction sheet.

Will this 4-cell 48Wh battery work reliably in an older ProBook 640 G4 that currently uses an HSTNN-LB8F pack?

Yes — the CD03XL replaces part numbers HSTNN-LB8F, HSTNN-IB8B, HSTNN-UB7K and 931702-421, so it fits and communicates correctly with the G4 platform.
