Cr2032 Voltage Range

The voltage is more affected by the instantaneous current draw than by the charge level.

Cr2032 voltage range.

1 microampere energy density. 235 mah to 2 0 volts rated at 15k ohms at 21 c typical weight. 198 milliwatt hr g 653 milliwatt hr cc typical li content. A good cell will not drop below 2 5v at room temp under load its easily seen in a typical.

210 mah on continuous discharge at 20 under 15kω load to 2 0v end voltage 2 4 outer dimensions. This can vary by brand however which is why we have provided datasheets for all of the major cr2032 brands in our datasheet section. Outer dimensions shall be as shown in fig. Cr2032 batteries all nominally have a voltage of 3 volts and open circuit voltages of approximately 3 6 volts.

0 109 grams 0 0038 oz. Cr2032 provide a nominal voltage of 3 0v to power up a simple led we need a minimum voltage of 2 2v so we have used the resistance for protection or current limiting. What voltage do cr2032 batteries have. 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.

Ansi neda 5004lc iec cr2032 nominal voltage. Just measuring with a multimeter might deliver false results. How do you check a coin cell button cell battery to see if it still has charge left. Varta cr2032 lithium 230ma.

3 0 volts typical capacity. A better test is load the cell briefly with 400 ohms and check the voltage simultaneously. 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. Lots of power in an ultra compact design.

The panasonic lithium coin cr2032 battery has a high voltage of 3v. High reliability and safety. 3 2 g 2 6 country of origin. You have enough with one lithium battery in comparison to 2 3 or more traditional batteries.

Choose the lithium coin cr2032 battery as a powerful source of energy for your small devices.
