This charger will charge battery or super-cap to either pre-programmed voltage or to the voltage of the cell that we want to match (<3.3V). The charged cell/super-cap can be charged up to 4V. Charge current can be chosen to be either 8mA or 25mA. These are max charging current for Tadiran HLC batteries of 2 sizes (hybrid rechargeable cell and super-cap). This was just a project to learn; no use in production settings, maybe usefull for R&D.
History
this one has improved "Charging" work. Steady when controlling current, blinking with low frequency when topping off.

good. Charge current tightly controlled and so is the battery final voltage.; Ready to go. I will not play with it anymore.
