A smoothing capacitor is not necessary because batteries charge better with slightly choppy current. I have also used this charger as a power supply for things like a hot wire cutter. WALTER Battery charger with starter aid for vehicles with 6 V or 12 V power supply and fast charging through charging current boost. Automatic Battery Charger Circuit for 12V & 6V Battery techstudycell OctoMini Projects 12 Comments Description: In this electronics project, I have explained how to make automatic battery charger circuit for any battery on the zero PCB. This prevents sparking that could possibly ignite hydrogen gas from the charging. Then disconnect the aligator clips from the battery. Disconnect the AC cord after 12 or more hours. Set the base of the charger someplace safe. Connect the red aligator clip to the red battery terminal and the black to the black. To use: Select 6 or 12 volts with the switch. Notice the strain relief for the output cord. I simply glued the bridge rectifier to the plywood with hot glue. Watch the output polarity so the + terminal on the rectifier connects to the wire for the red aligator clip. Put a rubber band on the handles of a needle nose plier and clamp the plier jaws on the lead you want to solder. It is a good idea to use a heat sink when soldering diodes to protect them from too much heat. This made a convenient base or support for the rectifier. In that case, the dome light will remain on all night and the battery will be very low in the morning. I bent the input (AC) leads in one direction and the output (DC) leads in the other direction. It is handy to have a small battery charger for your automobile, especially if someone parks it in your garage for the night with a door just slightly ajar. I found it easier to get a rectifier ready to use. Of course you can use individual diodes to make a bridge rectifier. If you look for a 12 volt transformer you may at first be frustrated because you can find only 13.4 volt transformers. When the voltage passes through the diodes in the rectifier it drops 0.6 volt for each of two diodes to roughly 12 volts. Note: The output of the transformer is actually about 13.4 volts. At the time I made this charger I helped to maintain an older farm tractor with a 6 volt electrical system. The center tap allowed the output to be either 6 or 12 volts.

Some friends have also borrowed it when their batteries were dead and it worked for them. But, it has gotten me out of several jams. The transformer puts out about 3 Amps., so it is ideal as a trickle charger. Similar transformers can be found at places like Radio Shack. Sending it back would have cost as much as the transformer.
