Charging Your Car Battery
If you havent been driving your car or its been left sitting idle, you may not have enough power in your battery to start the engine. And while it may seem like a good idea, running your vehicles engine five minutes a day is not enough to maintain your car battery.

Having confirmed that all power is off, you can begin to remove the negative or ground cable for your cars battery. Its almost always a black cable marked with a – symbol. The positive cable will be red and display a + symbol.
Your battery may also have plastic caps over its terminals that must be pried free for you to remove the cables. If these caps are present, remove them if necessary to access the terminals.
Use a socket wrench to loosen the negative cable, then carefully pull it away from the battery. Ensure that the negative cable is situated far from the positive cable to prevent a charge from transferring between the two sources.
Youll need to repeat the removal process for the positive cable and terminal. Move the positive cable away from the negative terminal for the same reasons described above.
