charge 2003 cadillac deville battery + demonstration + illustrations
Where do I put negative cable of charger on the battery. I don't want to ruin
battery or electrical system.
Negative - black, positive - red
When charging a battery I always remove the battery from the vehicle first. Remove the negative (-) battery cable first, then the positive (+) battery cable. Place the battery on a sturdy table, shelf, floor, etc. in a well ventilated area. Charging a battery can produce flammable hydrogen gas! Put the charger leads on the battery before plugging in the charger so there's no sparks when you hook up the charger leads. Follow the instructions for your charger as far as using it goes. Charging times, amps, etc. HTH. -Jim
