A car’s battery is essential for starting the engine and powering the electrical accessories. When the battery dies the car won’t start. Replacing a dead battery is usually a simple job that you can do yourself. The hardest part is often finding the right battery for your car.
Before you replace the battery it’s a good idea to check the battery terminals and clean them if necessary. A build-up of corrosion can prevent the battery from starting the car.
To replace the battery you’ll need a few tools:
A socket wrench and a socket that fits the battery terminals
A Phillips screwdriver
A set of jumper cables
Most batteries are located in the engine compartment either under the hood or in a side panel. The battery will be held in place by a bracket and secured with bolts.
To remove the old battery first disconnect the negative terminal (-). This is usually the black cable. Then disconnect the positive terminal (+) which is usually red. Remove the bolts that hold the battery in place and lift the battery out.
Installing the new battery is the reverse of the process. First connect the positive terminal (+) to the new battery. Then connect the negative terminal (-). Finally secure the battery in place with the bolts.
It’s important to use the right battery for your car. The size shape and terminals must all match the old battery. You can usually find the right battery by consulting your owner’s manual or a dealer.
Once you’ve installed the new battery start the engine and let it run for a few minutes. This will help charge the battery. If the engine won’t start you may need to jump-start the car.
Jumping a car with a dead battery is a simple process. First connect one end of the positive jumper cable to the positive terminal of the dead battery. Then connect the other end of the positive cable to the positive terminal of the good battery.
Next connect one end of the negative jumper cable to the negative terminal of the good battery. Finally connect the other end of the negative cable to a bare metal surface on the car such as a bolt.
Once the cables are connected start the car with the good battery and let it run for a few minutes. This will charge the dead battery and allow you to start the car.
If you don’t feel confident replacing the battery yourself consult a professional. Replacing a battery is a simple job but it’s always best to err on the side of caution.
