replace car battery

Procedure

1. With the engine off, pop the hood and find the battery. Detach the negative (black) battery cable from the battery. First loosen the nut with a combination wrench. A better tool to use would be battery pliers or a battery wrench.
2. Twist and pull up on the end of the cable with your hand. If it does not come off easily you may want to purchase a battery terminal puller. This will help prevent damage to your battery or cables. It is not recommended to use a screwdriver as a pry-bar; this could break off your battery terminal or cause other damage.

3. Detach the positive (red) battery cable from the battery using the same method.
4. Using a combination wrench or a socket and ratchet, remove the battery hold-down clamp.
5. Take the battery out of the battery tray. Batteries are heavy, so grab from the bottom using both hands. If the battery has a handle, use that instead.
6. Use either a battery cleaning solution or the baking soda and water mixture to thoroughly clean any corrosion that may be left behind on your battery tray and hold down clamp from your old battery.
7. Clean the battery cable connectors with a wire brush. To remove heavy corrosion from the connectors, use battery-cleaning solution.
