Replacement Battery for ThinkPad X1 Carbon

The KingSener 45N1070 is a new lithium-ion replacement battery built for Lenovo ThinkPad X1 Carbon models including the 3443, 3444, 3446, 3448, 3460 and 344325C series. It delivers 14.8V and 3.11Ah for 46WH of capacity. The black pack replaces part numbers 45N1070, 45N1071 and 4ICP4/56/128.

Who This Suits and Who It Does Not

This battery suits owners of the listed ThinkPad X1 Carbon models who need a direct replacement for a worn or failed original pack. It is not for users of other ThinkPad lines such as X1 Yoga, T-series or X-series machines. Buyers needing a higher capacity than 46WH or a different voltage should look elsewhere.

Voltage and Capacity Match Requirement

The single specification that decides fit is the 14.8V 3.11Ah 46WH rating; your laptop must require exactly this voltage and capacity. If the original battery shows a different voltage or watt-hour value this pack will not work.

Questions about this item

Does the KingSener 45N1070 battery arrive as a standalone unit or with any cables?

The KingSener 45N1070 is supplied as the battery module only; no cables, tools or adapters are included in the package.

How do I know whether the 45N1070 or 45N1071 part number matches my ThinkPad X1 Carbon?

Both part numbers replace 45N1070, 45N1071 and 4ICP4/56/128 and fit the ThinkPad X1 Carbon models 3443, 3444, 3446, 3448, 3460 and 344325C.

What does the 14.8V 3.11Ah 46Wh rating mean for daily runtime on my X1 Carbon?

The 14.8V 3.11Ah 46Wh rating matches the original specification, so the battery should deliver the same runtime as the factory pack when new.
