Compatible HP ProBook G8 replacement

This 11.4V 45Wh lithium-ion battery replaces the RH03XL and multiple HP part numbers across ProBook 430 440 445 450 630 640 650 G8 series and Zhan 66 Pro 14 G4 models. It supplies 3790mAh capacity in a three-cell black pack rated for up to 1000 recharge cycles.

Installation with included toolkit

The package provides one battery, printed instructions and a 4+1 matching tool set so most owners can swap the old pack without sourcing extra drivers. Common issues are forgetting to disconnect the internal cable before removing screws and misaligning the connector on reassembly.

Limits of three-cell 45Wh design

A three-cell 45Wh pack cannot match the runtime of higher-capacity six-cell or long-life options that some configurations accept. Buyers who need all-day operation away from mains power should verify whether their chassis supports a larger capacity alternative.
