Cr2032 Battery Voltage Range

Just measuring with a multimeter might deliver false results.

Cr2032 battery voltage range.

High reliability and safety. An insulated top cap is the negative terminal. 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. 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.
