Replacement Battery for ProBook 635 Aero G7

This new lithium-ion battery delivers 42Wh at 11.55V and matches part numbers GR03XL, M12328-2D1 and TPN-DB0D. It is built for the ProBook 635 Aero G7 series including models 2N2T0UT, 2N2T4UT, 2W0R2PA and 320T4PA. The black pack installs directly without adapters.

Buyers Restoring Original Runtime

Owners of a compatible ProBook 635 Aero G7 whose original cell no longer holds charge will regain factory runtime. The unit is not suitable for other laptop families, for systems requiring a different voltage or capacity, or for users needing a higher-watt-hour pack than 42Wh.

Steady Output Through a Full Cycle

The lithium-ion chemistry maintains a stable 11.55V across the discharge curve so the laptop runs at consistent performance until the low-battery threshold. Capacity remains at 42Wh after repeated cycles and the pack meets the 12-month warranty period under normal daily use.

Questions about this item

My ProBook 635 Aero G7 originally used part number GR03XL — does this battery replace it directly?

Yes, this battery lists GR03XL among its replace part numbers, so it fits the same ProBook 635 Aero G7 models.

I am keeping my current AC adapter — will the laptop charge this 11.55 V lithium-ion pack normally?

The original adapter for the ProBook 635 Aero G7 is designed for an 11.55 V battery, so it will charge this pack as intended.

After fitting the battery, how can I confirm the 42 Wh capacity is recognised by the system?

Check the battery report in the operating system; it should show a design capacity of 42 Wh for this pack.
