Cr2032 voltage range.
Just measuring with a multimeter might deliver false results.
What voltage do cr2032 batteries have.
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.

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.
This can vary by brand however which is why we have provided datasheets for all of the major cr2032 brands in our datasheet section.

A good cell will not drop below 2 5v at room temp under load its easily seen in a typical.
Varta cr2032 lithium 230ma.
Cr2032 batteries all nominally have a voltage of 3 volts and open circuit voltages of approximately 3 6 volts.
The voltage is more affected by the instantaneous current draw than by the charge level.
Lots of power in an ultra compact design.
How do you check a coin cell button cell battery to see if it still has charge left.
High reliability and safety.
