Compatible HP ProBook models

This Cameron & Co DS-CS-HPG450NB lithium-polymer battery replaces the original power cell in HP ProBook 430 G4, 430 G5, 440 G4 and MT20 notebooks. It delivers a 4 Ah capacity in a black housing designed to match the factory fit. The unit is supplied new and ready for installation.

Check your part number before ordering

Verify that your current battery carries one of the listed part numbers such as 851610-850, 851610-855, RR03048XL or RR03XL. Confirm the laptop model appears in the supported list, as ProBook 430 and 440 variants outside the G4 and G5 generations are not covered. Ensure the battery compartment uses the same connector layout.

Replaces worn or failed original cells

The battery restores mobile runtime when the original pack no longer holds charge or shows swelling. It is a direct swap for the factory unit in the compatible ProBook models, so the upgrade is worthwhile whenever the existing battery cannot sustain a full work session. Users needing higher capacity than 4 Ah or a different form factor should look elsewhere.

Questions about this item

Does the DS-CS-HPG450NB battery pack include any screws or tools for fitting it into an HP ProBook 430 G4?

The battery is supplied as a single unit; no screws, tools or additional hardware are included in the box.

Should I choose the 4 Ah version or is there a higher-capacity option for the ProBook 440 G4?

This model is offered only in a 4 Ah capacity; no larger-capacity variant is listed for the ProBook 440 G4.

What runtime can I expect from the 4 Ah rating when the battery is installed in an HP MT20?

The 4 Ah rating indicates the charge the cell can deliver; actual runtime in an MT20 depends on the workload, screen brightness and power settings.
