Simplified circuit 2 volt Car Battery Chargers

Cars simplest operation is continuous battery charging device with a few amperes during the ON period. If the power is off in OFF time, the battery will be too expensive, electrolytes lost through evaporation, and the plate-elements will likely be destroyed. Above circuit will eliminate the problem by monitoring the condition batterys cost through control circuit to apply retroactively by the high cost of current until the battery is completely charged. When charging is completed, he turned to the red LED (LD2) and disable the charging circuit. This circuit is taken to cost ONLY 12V battery.
