Your homemade charger is now ready to use. Use a nail or a drill to make two holes in the can, one near the top and one near the bottom. Answer You can plug the adapter into an outlet and then connect the positive and negative leads from the adapter to the corresponding terminals on the battery. To do this, youll need to disconnect the positive (red) wire from the 220v AC power source, and then connect it to the positive (red) terminal on the 12v DC power source. Household battery chargers are designed to charge household batteries, which are much smaller than car batteries. The charger should turn on when the voltage drops to about 12.5v. Batteries can be recharged by reversing the process that takes place when they are used. 4. The rectifier should be able to handle the amount of current your power source produces. -Some wire The advantage of this type of charger is that it is very simple and inexpensive to build.
