6V 12V Constant Current Battery Charger Circuit PCB Layout Added
The circuit diagram of the charger shown in Fig.1 is centered around the L200 type voltage regulator IC, which ensures constant charging voltage to any connected 6V, 12V battery.
R2 and R3 are the current limiting resistors. The charging current is selected by altering the values of R2 and R3. Strictly, the necessity of R2 holds good if the charging current exceeds 500 mA. The current required for charging is obtained by the relation: l(charging) = 0.45(R2+R3)/ R2R3
The circuit diagram and PCB layout of the above explained 6V 12V constant current battery charger is shown below:
