CN3085 Ni-Cd Ni-MH battery charger

Overview

AA battery charger made with CN3085 chip.
Single cell or two cells in series charging.
The circuit diagram is very simple, so I won’t go into too much detail. The switch can realize single cell charging and 2 cells charging in series. If you are interested, you can change it to four cells for charging.
