Replacement battery for ThinkPad X1 Carbon models

This Dr. Battery MPL10233P-30 unit replaces the original Lenovo 45N1070 and 45N1071 packs in ThinkPad X1 Carbon 3443, 3444, 3448 and 3460 laptops. It is a new lithium-polymer module rated at 14.8V and 47Wh, built to match OEM specifications for owners needing a direct swap.

Capacity and runtime envelope

The 3200mAh cell delivers 47Wh of energy, restoring the factory runtime envelope for typical office workloads and media playback. Heavy multi-core tasks or sustained high brightness will deplete the charge faster, and the pack cannot exceed its rated watt-hour capacity.

Smart-chip protections and fit verification

An integrated control chip manages quicker charging, lower self-discharge and safeguards against short circuit, overheat and overload conditions. The supplier stresses that buyers must verify their exact laptop model and original battery part number before installation to ensure mechanical and electrical compatibility.

Questions about this item

Will this MPL10233P-30 battery fit my ThinkPad X1 Carbon 3443 CTO without changing the chassis or connectors?

Yes — it replaces Lenovo part numbers 45N1070 and 45N1071 and matches the 14.8 V, 47 Wh specification for the 3443, 3444, 3448 and 3460 models.

How can I confirm the smart control chip is balancing the cells correctly after I install the battery?

Open the Lenovo Vantage battery page; the reported design capacity should read 47 Wh and the cycle count should start at zero, showing the chip is communicating properly.

Does the box include the 45N1070 label and installation tools, or must I buy a screwdriver kit separately?

The package contains the Dr. Battery MPL10233P-30 unit only; a small Phillips screwdriver for the bottom-case screws is not included.
