Replacement battery for ThinkPad X1 Carbon 2015

This 15.2 V 51 Wh lithium-ion pack replaces Lenovo part numbers 00HW002, 00HW003, SB10F46440 and SB10F46441. It fits second-generation 2014 models 20A7 and 20A8 and third-generation 2015-2016 machines. The four-cell design meets OEM specifications and carries CE, FCC and RoHS safety certifications.

Sustained runtime with circuit protection

The battery delivers up to 500 recharge cycles while built-in circuitry guards against overcharge, overdischarge, over-temperature and short-circuit conditions. Using the original charger maintains consistent charge rates and low power consumption during extended work sessions away from mains power.

Upgrade from a degraded original pack

Owners of compatible X1 Carbon units whose factory battery no longer holds useful charge will regain full mobility. Buyers who need a higher-capacity cell than 51 Wh or a different voltage should look elsewhere, as this pack matches the original specification exactly.

Questions about this item

Does the 51 Wh battery generate extra heat or drain faster under all-day use?

The 4-cell Li-ion pack is built with over-temperature and short-circuit protection and rated for up to 500 recharge cycles, so it runs at normal laptop temperatures during continuous operation.

What must I already own to install this 15.2 V replacement battery?

You need a compatible ThinkPad X1 Carbon 2nd Gen 2014 or 3rd Gen 2015-2016 chassis and a small screwdriver to open the back cover and connect the battery interface to the motherboard.

Will this 00HW002 battery work alongside the original 45N1701 charger and motherboard in my 2015 X1 Carbon?

Yes, the pack matches part numbers 00HW002, 00HW003, SB10F46440 and SB10F46441 and meets OEM standards, so it charges and communicates normally with the existing 15.2 V charging circuit.
