Replacement Battery for ThinkPad X1 Tablet Gen 3

This GreenTechLLC battery replaces the original Lenovo power pack for the ThinkPad X1 Tablet 3rd Gen, including the 20KJ and 20KK variants. It is a brand new, non-OEM unit built to match the factory form factor and connector layout. Installers can swap the old pack without any modifications to the tablet chassis.

42 Wh / 5440 mAh Capacity at 7.72 V

The single figure that determines fit and runtime is the 42 Wh energy rating delivered at 7.72 V from a 4-cell lithium-ion assembly. This matches the OEM specification exactly, so the tablet's fuel gauge and power management behave identically to the original battery. Buyers who need a higher capacity pack for longer unplugged sessions cannot use this part.

Tested Unit with CE, FCC and RoHS Marks

Every battery ships after a test cycle that verifies voltage stability, circuit protection and low self-discharge. The certifications mean the pack meets basic electrical safety and substance restrictions for the markets where those marks are recognised. No cables, tools or software utilities are included in the package.

Questions about this item

How long will the 42 Wh capacity run my ThinkPad X1 Tablet Gen 3 on a single charge?

Runtime depends on screen brightness, workload and power settings; the 42 Wh rating matches the original battery so you can expect similar battery life to when the tablet was new.

Does the 7.72 V output match the voltage my ThinkPad X1 Tablet Gen 3 expects?

Yes, 7.72 V is the exact nominal voltage specified for the X1 Tablet 3rd Gen, so the tablet's power management will recognise and charge it normally.

Will the four-cell pack fit inside the X1 Tablet 3rd Gen chassis without modification?

The battery is built to the same 4-cell form factor as OEM part 01AV454 and seats directly in the tablet's internal battery bay with no adapters needed.
