When was the last time you replaced your car battery? It should last about six years, but that depends on how you treat it and the climate you live in.
Eventually, all car batteries fail, and that’s when they need to be replaced. Knowing how to replace your car battery can save you time and money because you can do it yourself.
Read on to learn how to safely replace your car battery.
Finding the Battery
The first step is to find the old battery. For most vehicles, the battery is located under the hood of the car.
Once under the hood, it could be anywhere in the windshield behind the headlights. If you don’t see it right away, try looking under the plastic cover.
If the battery isn’t under the hood, don’t panic. Try looking under the car seat or in the trunk.
Disconnecting an old battery
To disconnect the battery, disconnect the negative terminal first. Then disconnect the positive terminal. If you’re lucky, there’s a quick-release latch that makes it easy to disconnect.
Many cars still require a wrench to loosen the bolts on the terminals. Manufacturers use different sizes of wrenches, so check the manual or try a few wrenches until you find the right one.
Turn the bolt to the left to loosen it. The bolt should be tight, but not too tight. Never let the wrench touch both terminals at the same time.
This will conduct electricity and may cause sparks or electric shock. The last thing you want is sparks.
After removing the terminals, tuck them to the curb.
Installing a New Battery
When the old battery is used up, toss the new lithium battery into the empty space. Then, perform the removal steps in reverse to secure and connect the new battery.
Start by securing the battery with the retention system. This will secure the battery while you connect the terminals. Connect the positive terminal first. Do not let the wrench touch any other metal.
Then connect the negative terminal. Make sure both terminals are secure, but not too tight or you risk breaking them. The last step is to replace the plastic cover.
Remember How to Replace a Car Battery
Now that you’ve learned how to replace a car battery, remember these steps. When the dreaded day comes and your battery is dead, you can easily replace it.
Be safe when replacing your battery. Always disconnect and connect the positive and negative terminals in the correct order. Be careful not to damage the battery when removing and installing it as well.
