The panasonic lithium coin cr2032 battery has a high voltage of 3v.
This can vary by brand however which is why we have provided datasheets for all of the major cr2032 brands in our datasheet section.
Voltage v load at 50 discharge as can be seen the voltage is quite steady for loads up to 200ua but begins to fall away very rapidly as the load increases from there.
High reliability and safety.

A better test is load the cell briefly with 400 ohms and check the voltage simultaneously.
How do you check a coin cell button cell battery to see if it still has charge left.
If the battery is at end of life the discharge voltage will be in or past the knee of its discharge curve unloaded so the lower it is past 3v the more worn it is.
