Step-by-Step Process
Step 1:
Open the hood of the car by pulling the lever until you hear the hood pop open.
Wear protective gloves when dealing with a car battery to protect against potential battery acid.
Step 2:
With the hood now open, identify the battery and the part number.
When replacing the battery, make sure that the new battery and old battery have the same part number to avoid issues.
Step 3:
Use a torque wrench with a 9 mm attachment to unscrew the negative clamp and remove it from the terminal. Do the same with the positive terminal.
Make sure that no metal pieces touch the terminals at the same time, and that the clamps don't touch each other.
Step 4:
If the terminals are corroded, take the corrosion brush and insert the terminal into it and turn until the corrosion is gone.
If there is no corrosion, go to the next step.
Step 5:
Remove the battery from the base.
Be careful as the battery is heavy. To prevent leakage of battery acid, never turn it upside down.
Wipe down the base and clamps with a damp rag to remove any dirt or dust that might be present.
Step 6:
Dry the base and clamps fully with a dry rag.
The clamps must be fully dry.
Place the new battery into the base, making sure that the bracket on the bottom is in place.
Step 7:
To prevent corrosion, you can place dielectric grease or petroleum jelly on the terminal before placing the clamps, but it isn't necessary.
Place the clamps onto the terminal.
Screw the negative clamp on first.
Don't screw it on too tight.
Repeat this step with the positive clamp.
Step 8:
Remove all tools from the battery.
Make sure to keep track of the time your battery has been in your car. They should be replaced every 3-4 years.
Do not throw away old batteries. They can be taken to most automotive shops to be discarded safely and appropriately.
