Replacement battery for ProBook 635 Aero G7

This KingSener GR03XL unit is a new lithium-ion battery built to replace the original power pack in HP ProBook 635 Aero G7 notebooks. It matches the factory voltage of 11.55V and delivers a rated capacity of 42WH or 3636mAh. The part number GR03XL aligns with OEM references such as TPN-DB0D and M12328-2D2.

Steady output for mobile workloads

The 42WH cell sustains consistent voltage across the discharge curve so the ultraportable maintains performance during long meetings or travel days. Rated at 11.55V it feeds the platform without the dips that trigger throttling on lighter loads. Users can expect reliable runtime proportional to the 3636mAh specification under typical office mixed use.

Black Li-ion pack with exact-fit mounting

The black housing follows the OEM footprint so it seats securely in the ProBook 635 Aero G7 chassis without gaps or flex. Connectors line up with the motherboard header for a firm click on installation. Condition is 100 percent brand new and the unit carries a one-year warranty from the manufacturer.

Questions about this item

Does the 11.55 V GR03XL generate extra heat or drain quickly under all-day load?

The 42 Wh lithium-ion pack runs at the same 11.55 V as the original HP ProBook 635 Aero G7 battery, so thermal behaviour and runtime match the factory specification.

What must I already own to install this GR03XL replacement?

A compatible HP ProBook 635 Aero G7 chassis and a small Phillips screwdriver to open the bottom case and swap the battery.

Will the GR03XL fit my ProBook 635 Aero G7 2W8S4EA alongside the original cooling assembly?

Yes — the GR03XL replaces part numbers GR03XL, TPN-DB0D, M12328-2D2 and HSN-I39C used across the 2N2T0UT, 2W8S4EA, 306A9EA and other listed 635 Aero G7 models without interfering with the existing fan or heatsink.
