Energizer lithium coin cell 2032 3v battery 2 per pack.

Cr2032 battery voltage new.

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. Firstly the voltage does not change very much over the first 75 of the discharge. Lithium manganese dioxide cr2032 batteries supply reliable power to a wide variety of household electronics. An insulated top cap is the negative terminal.

Cr2032 batteries all nominally have a voltage of 3 volts and open circuit voltages of approximately 3 6 volts. However a cr2032 battery 3v can last up to 10 years when used in computer bios. Typically they can last anywhere between 1 2 years. 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.

A watch battery or button cell is a small single cell battery shaped as a squat cylinder typically 5 to 25 mm 0 197 to 0 984 in in diameter and 1 to 6 mm 0 039 to 0 236 in high resembling a button a metal can forms the bottom body and positive terminal of the cell.

Type maximum current cr2032 10ma cr3032 15 ma. What voltage do cr2032 batteries have. 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. For example say a cr2032 battery is used in sample circuit a in combination with a main power source 5 volt.

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.
