47 Wh Li-ion replacement for ThinkPad X1 Carbon

This 14.8 V lithium-ion pack replaces part numbers 45N1070 and 45N1071 in ThinkPad X1 Carbon models 3443 3444 3448 3460 3462 and 3463. It restores mobile power for professionals who rely on the ultraportable chassis for daily work.

Four-cell design fits the original battery bay

The 3180 mAh unit slides into the existing compartment without adapters or cable changes. It frees the notebook from wall power so the system can resume its thin-and-light role on trains in cafés or between meetings.

Grade A cells hold capacity through repeated cycles

After an initial full charge and two calibration cycles to 1 % the pack stabilises at its rated 47 Wh. Steady discharge under typical office loads avoids the sharp voltage drops that cause sudden shutdowns on worn original batteries.
