Hi,
For this small temperature sensor I'm developing I search guidance on cell selection.
The sensor will sleep at just a couple microamps and transmit every 5-30 minutes with bursts up to 13mA when transmitting. CR2032 works well today but discharges much quicker when put in a freezer. Looking at BR2032 which is recommended for lower currents and has wider temperature range, but will it handle the bursts?
I also saw these, which offer much more capacity at a sacrifice of slightly larger diameters. But rated continious currents at only 30µA, I'm not sure if they can handle the burst currents for the radio?

Any insight on the matter is highly appreciated.
