Replacement battery for HP ProBook G4 and G5

This new lithium-ion pack replaces the original RR03XL unit in ProBook 430 440 450 455 and 470 models from the G4 and G5 series. It carries part numbers HSTNN-PB6W HSTNN-UB7C and several OEM codes listed by the supplier. Buyers with other laptop lines or newer ProBook generations cannot use this pack.

Thermals noise and power draw in normal use

The 11.4 V 48 Wh cell delivers the same voltage and capacity as the factory battery so thermal behaviour and runtime match the original design. No active cooling or fan is present and the unit adds no audible noise. Power draw follows the laptop's own management without extra overhead.

Deciding specification 48 Wh capacity at 11.4 V

The single figure that confirms fit is the 48 Wh rating at 11.4 V which must match the label on the battery you are replacing. If your existing pack shows a different watt-hour value or voltage this unit will not be compatible.

Questions about this item

How do I install the RR03XL 48Wh battery in my ProBook 450 G4 and which step is often missed?

Power off the laptop and unplug the AC adapter; remove the base screws, lift the bottom cover, disconnect the old battery cable before unscrewing the pack, fit the new unit, reconnect the cable first, then refit the cover and screws.

What replacement will the RR03XL 48Wh pack need after extended use?

The lithium-ion cells degrade over charge cycles; when runtime no longer meets your needs the entire pack must be swapped for a new RR03XL or compatible HSTNN-PB6W unit.

What limit appears first when the RR03XL 48Wh battery runs under sustained load?

The 48 watt-hour capacity sets the total energy available; under continuous high draw the pack will reach its voltage floor and trigger system shutdown before thermal limits are hit.
