If your question is in regard to the X360 15-er000 model series, it does not have a separate CMOS/RTC battery.

 

The main battery also serves as the CMOS/RTC battery to maintain the BIOS and system clock settings.

 

Below is the link to the service manual.

 

Maintenance and Service Guide

 

Chapter 3 has the list of parts. 

 

You will not find a CMOS or RTC battery part number.

 

Chapter 5 has the component removal and replacement procedures.

 

You will not find a procedure to remove or replace a CMOS or RTC battery.
