Replacement CMOS Battery for ThinkPad X1 Carbon

This FOCUSTEC CR2016 CMOS battery replaces the original BIOS coin cell in ThinkPad X1 Carbon 2nd through 6th generation laptops and the ThinkPad S3 Yoga 14. It uses a lithium-ion chemistry rated at 3 V and arrives with a two-pin, two-wire cable and heat-shrink insulation for a secure fit. The compact unit slides into the motherboard socket without modification.

Upgrade from a dead or failing BIOS cell

Swap this battery when the system clock resets, BIOS settings disappear or the laptop refuses to boot because the RTC voltage has dropped. The replacement restores reliable timekeeping and firmware configuration retention. The job typically takes about 10 minutes with basic tools and no soldering required.

Suits owners of the listed ThinkPad models

This part suits users who need a direct-fit CMOS cell for the specific X1 Carbon and S3 Yoga 14 models named above. It is not for laptops that use a different coin-cell size, a different connector pinout or a soldered-in RTC battery. Buyers with other ThinkPad series or non-Lenovo machines should verify the exact CR2016 2-pin requirement before ordering.
