Exact-fit replacement for X1 Carbon Gen 2

This lithium-ion battery replaces Lenovo part numbers 45N1700, 45N1701, 45N1702 and 45N1703 in the 2014 ThinkPad X1 Carbon Gen 2 models 20A7 and 20A8. It restores mobile power to a machine that cannot run without a working pack. Buyers with any other ThinkPad model or a Gen 1 or Gen 3 X1 Carbon cannot use this unit.

Drops into the existing bay with no extra parts

The pack connects directly to the laptop's internal battery connector and is held by the original screws. No adapter cables, caddy brackets or firmware tools are required. The 14.8V/15V output matches the system's charging circuit, so the machine recognises the cell immediately. A 45Wh capacity simply replaces what was there.

Single battery in the box

The package contains one black Li-ion cell and nothing else. No driver disc, calibration utility or installation guide is bundled. The 12-month warranty covers the battery itself; any screwdrivers, anti-static straps or diagnostic software must be sourced separately.

Questions about this item

How long will the 45Wh capacity last before the battery needs recharging under sustained load?

The 45Wh lithium-ion cell delivers up to 45 watt-hours per charge; actual runtime depends on the laptop's power draw.

Does the battery generate noticeable heat or fan noise during all-day operation?

The battery itself has no moving parts and produces minimal heat; any warmth or fan activity comes from the laptop's own thermal system.

Which ThinkPad models must I already own for this 45N1700-series battery to fit?

It fits ThinkPad X1 Carbon Gen 2 units with model numbers 20A7 or 20A8 from 2014.
