Lifespan of CR2032 batteries and LEDs : r/AskElectronics
Both AA and AAA batteries have far more "fuel" (mAH) than a CR2032. Coin lithium coin batteries are meant for very low current draw for a very long period of time, and an LED isn''t very low current. I''m not saying you can''t drive an LED with a lithium coin battery, but instead that it won''t last very long compared to AA batteries.

This characteristic is a double-edged sword: while it limits the battery''s efficiency in high-drain applications, it also prolongs the battery''s life in low-drain scenarios. When a high current is drawn, as in high-drain applications, the internal resistance causes a significant voltage drop, which in turn reduces the available power.

Is slow charging a Lithium Polymer battery any better for it?
Every lithium charger that I have seem charges on the CC-CV algorithm and terminates charge when the current in the CV stage gets to 1/10 the current of the CC stage. So if you start with a very low charge current, the charger won''t terminate charge until the current is 1/10 of that small current. The result will be a very full battery!
