If your Chevy battery is dead, you'll need to charge it before you can use your car. To do this, you'll need a charger and some basic knowledge of how to use it.
First, make sure that the charger is rated for the voltage of your battery. Most Chevy batteries are 12 volts, but some are 6 volts. If you're not sure, check the label on the battery or consult your owner's manual.
Next, connect the positive (red) lead from the charger to the positive terminal on the battery. Then, connect the negative (black) lead from the charger to a metal ground on the car body - not to the negative terminal on the battery. Finally, plug in the charger and turn it on.
Charging a Chevy battery is pretty simple as long as you have a good quality charger and follow these basic steps. Just be careful not to overcharge your battery - remove the charger once the voltage reaches 14-15 volts on a 12 volt system, or 7-8 volts on a 6 volt system.
