Exploring the Real Capacity of CR2032 Batteries
Was cool to be able to do this article, taking a deep dive into the real capacity of CR2032 batteries. the TL;DR version is that they are meant for REALLY low current draw over a long time, but it appears that you can stretch this for more inefficient use as needed: https://embeddedcomputing.com/technology/open-source/development-kits/cr2032-maximum-current-capacity-datasheet-reality-and-alternatives

CR2032 Maximum Current Capacity: Datasheet, Reality, and Alternativ...
Consider the humble CR2032 battery. Roughly the size of a quarter and capable of supplying around 225mAh at a nominal 3V, these little coin cells are used to power all manner of small electronic devices that require a small amount of power. One might assume they can easily discharge 10mA or so, to power something like an ATtiny85 microcontroller...

I used the High-drain lithium coin batteries from Murata for asset tracking and found this article to be very detailed and insightful. Thanks for sharing data from ur experiments. It would be great to see a similar analysis on small Li-Po batteries, as that would make an excellent read.
Well thank you! 🤔 That is not a bad idea.
