Cr2032 Battery Voltage New

Nominal voltage is 3 volts open circuit voltage of a new cell is 3 2 3 3 volts and cutoff voltage around 2 volts.

Cr2032 battery voltage new.

Firstly the voltage does not change very much over the first 75 of the discharge. However a cr2032 battery 3v can last up to 10 years when used in computer bios. Lithium manganese dioxide cr2032 batteries supply reliable power to a wide variety of household electronics. Two aspects of cr2032 lithium battery discharge performance need to be understood.

What voltage do cr2032 batteries have. As can be seen below there s only 200 mv difference between 100 charge and 25 charge for a constant low current draw of 190ua. A cr2032 is a small coin shaped battery which uses manganese dioxide lithium chemistry with a diameter of 20 mm and a height of 3 2 mm. Type maximum current cr2032 10ma cr3032 15 ma.

Typical discharge rate for cr2032 is in around 0 2 ma with the maximum continuous drain current of 3 ma and maximum pulse current of around 15 ma. For example say a cr2032 battery is used in sample circuit a in combination with a main power source 5 volt.

5 year warranty celewell 100 pack cr2032 battery 2032 ecr2032 230mah 3 volt lithium battery coin button cell 4 6 out of 5 stars 397 21 99 21. Cr2032 batteries all nominally have a voltage of 3 volts and open circuit voltages of approximately 3 6 volts. Since the permitted charge current is 10ma and this battery s voltage is 3v let resistance be r 5v 3v 10ma 0 2k ohm meaning that at least 0 2k ohm is required. 3v of power and 240 mah capacity delivers a reliable long lasting charge to your electronics.

The longevity of your 3v battery cr2032 depends on how much power your device uses.
