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.
