Simple alkaline battery charger schematic circuit

This simple schematic circuit was designed by Domenico Di Mario from Italy. It’s specifically designed to recharge an alkaline cells.

This circuit schematic diagram can be used with all types of alkaline cells. For AA cell it can take up to one day discharged can be recharged: it will take 1 day for a discharged AA cell or 9 V battery and up to several days for a large D type cell.

The orange LED will blink for around 5 times a second for a 1.37 V cell.

For a totally discharged cell, the blinking is faster but it will decrease until it will come to a stop when the cell is charged

To use high beta transistors such as BC337-25 or better BC337-40.
