Compatible ProBook models

This 3-cell lithium-ion battery fits HP ProBook 640 G2, 645 G2, 650 G2, 655 G2, 640 G3, 645 G3, 650 G3 and 655 G3 notebooks.

Verify exact model and voltage

Before ordering, confirm the laptop’s model number matches one of the listed G2 or G3 variants. The battery operates at 11.4 V and delivers 46 W of capacity; a different voltage or connector will prevent installation. Check the existing battery’s part number against the compatibility list to ensure a correct fit.

Steady output during extended sessions

Under sustained workloads the lithium-ion cells maintain a stable voltage curve rather than dropping sharply after a brief burst. The 3-cell design distributes load evenly, so the pack continues to supply consistent power through long document editing, video playback or web browsing sessions without sudden shutdowns.
