The impact of high pulse drain on CR2032 coin-cell battery capacity

Posted on Friday, January 6th, 2012 in documentation, power supply by the machinegeek


If you design circuits powered by CR2032 batteries here’s an article located by Joe Desbonnet which you should consider:

This is an interesting article on how the performance of a cell/battery under pulsed loads can vary dramatically depending on period, peak current, duty cycle and other factors. The article discusses the performance of a CR2032 button cell driving low power wireless protocols such as ANT+ and Bluetooth v4.0.
