1) First, remove the battery cables from the terminal posts. Remember to remove the (-) negative cable first. (This cable is usually black) and then the (+) positive cable. Don’t forget that all your stereo settings will probably be lost when the power is cut off.
2) Now you are ready to hook up the car battery charger to your car. But first, read the owner’s manual and insure that the model charger you are using is suitable for your car. Now, hook the (+) positive cable (red) to the positive terminal and then the (-) negative cable (black) to the negative terminal.
3) Now plug in your car battery charger and switch it on. Al light or some other indicator should turn on. (Consult your owner’s manual)
4) Wait for another indicator to come on to show that the charge is complete. Remove the cables starting with the (-) negative cable (black) first and reconnect your battery.
