Car Battery Charger from Spare Parts in Mint Tin

Step 3Usage

This is a relatively crude charger. As it does not have a precise termination voltage, it should not be left on the batter indefinitely. An overnight charge should be about the limit.

Plug the power supply in, and plug the auto power plug into a cigarette lighter outlet in the car. YOu should notice the dome lights and everything become a bit brighter. Make sure everything is turned off, and leave the car for 2 to 12 hours, longer maybe for a totally dead battery

This power supply provides a contant current of 1.2A. Depending on the power supply voltage, this peak current will diminish somehwat as the battery approaches full charge
