This is a circuit for a ML2032 lithium manganese dioxide button cell charger. It uses a LM317 voltage regulator in CCCV mode and charges with a bit less than 2 mA.

Here is the project with all the sources: https://codeberg.org/ncc1988/ml2032-chargers

Do not charge CR2032 button cells with this circuit, because they might explode!
