PowerWarehouse 3-cell replacement battery

This new 3-cell lithium-ion battery replaces the original pack in several EliteBook and Elite x360 models. It is intended for owners of the 14-inch 1040 G9, 13.3-inch 830 G9, 835 G9, 14-inch 840 G9 or 845 G9 who need a direct swap. Buyers with laptops outside this specific G9 series cannot use this part.

Straightforward internal swap

Installation requires opening the chassis and disconnecting the old pack, so basic disassembly comfort is needed. The battery matches the OEM form factor and connector, eliminating adapter cables. The main risk is damaging fragile ribbon cables or stripping small screws during reassembly if the correct tools are not used.

11.58 V 3525 mAh energy rating

The single specification that decides fit is the 11.58 V 3525 mAh rating combined with the listed OEM part numbers. Only systems designed for this exact voltage and capacity will charge and report capacity correctly. Machines that require a different cell count or voltage will not operate safely with this unit.
