Questions about this item

What laptop model does this CMOS battery fit?

This battery is made for the Lenovo ThinkPad Edge 15 inch series.

Will it work if my motherboard uses a soldered RTC cell instead of a removable one?

The part is a removable coin cell, so it only fits boards that have a standard holder for this type of battery.

How can I confirm the replacement is working after I install it?

After fitting the cell, power on the machine and check that the BIOS keeps the correct date and time through a full shutdown cycle.
