I say it just might be the :
Apple Menu (hold the 'alt' key down) select System Information.
That will list the 'model identifier' in the hardware section.
Enter that into google along with 'PRAM battery' or 'NVRAM battery' & you should find the battery type & probably the spec.
Chances are it is a coin cell…
this little battery.
