Replacement battery for ThinkPad X1 Carbon
This 14.8V 46Wh lithium-polymer battery replaces part numbers 45N1070 and 45N1071 in ThinkPad X1 Carbon models 3443, 3444, 3448, 3460, 3462 and 3463. It uses Grade A cells and carries FCC, CE and RoHS certification. The pack is supplied new and ready to install.
Thermals and power behaviour
The battery delivers its rated 46Wh at 14.8V with a 3.11Ah capacity. Grade A cells are specified for fast charging and low power consumption during normal operation. No active cooling or fan is present, so thermal output is limited to the cell chemistry under load.
Upgrade context and limits
This unit replaces an exhausted or degraded original battery in the listed X1 Carbon models. It restores the original runtime and charge-cycle count but does not increase capacity beyond the factory 46Wh specification. Buyers needing a higher-capacity pack or a different voltage will not be served by this part.

Questions about this item
How do I install the 45N1070 battery in my ThinkPad X1 Carbon 3444 and what step do people often miss?
Power off the laptop, remove the bottom case screws, disconnect the old battery cable before lifting it out, connect the new 14.8 V 46 Wh pack, then reassemble; the step most people skip is unplugging the internal battery connector first.
What replacement will the 45N1071 pack need after extended use?
The lithium-polymer cells degrade over time; when runtime drops below useful levels the whole 46 Wh battery must be swapped for a new 45N1070 or 45N1071 unit.
What limit appears first on the 4ICP4/51/95 battery during sustained heavy load?
The 3.11 Ah capacity sets the runtime ceiling; under continuous high drain the charge depletes fastest, forcing a recharge before voltage or thermal limits are reached.
