Cr2032 Voltage Range

1 microampere energy density.

Cr2032 voltage range.

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. Here are the latest datasheet appearance shape specifications features applications product data of micro batteries cr2032 specifications battery type coin manganese dioxide lithium batteries nominal voltage 3 0v nominal capacity 220mah standard discharge current 0 2ma operating temperature range 30 to 70 diameter inch 0 787inch diameter mm 20mm height inch 0 126inch height mm 3 2mm iec jis cr2032 mass oz 0 109oz mass g 3 1gother usage automotive smart key. The voltage is more affected by the instantaneous current draw than by the charge level.

198 milliwatt hr g 653 milliwatt hr cc typical li content. Ansi neda 5004lc iec cr2032 nominal voltage. How do you check a coin cell button cell battery to see if it still has charge left. Just measuring with a multimeter might deliver false results.

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. 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.

You have enough with one lithium battery in comparison to 2 3 or more traditional batteries. Lots of power in an ultra compact design. 3 0 grams 0 10 oz typical volume. High reliability and safety.

A good cell will not drop below 2 5v at room temp under load its easily seen in a typical. 3 0 volts typical capacity. 0 109 grams 0 0038 oz. 235 mah to 2 0 volts rated at 15k ohms at 21 c typical weight.

What voltage do cr2032 batteries have. 3 2 g 2 6 country of origin. 1 0 cubic centimeters 0 06 cubic inch max rev charge. 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.
