Can I Change The Battery In My Car Myself?

One of the most common questions we get asked here at the auto shop is whether or not customers can replace their car battery themselves. The short answer is yes, you can absolutely change the battery in your car yourself, but there are a few things you should know before attempting this task.

So, it’s important to take all the necessary precautions when handling a car battery, including wearing gloves and eye protection.

Second, you’ll need to know which type of battery you have in your car. There are two main types of batteries, lead-acid and lithium-ion. Lead-acid batteries are the most common type of battery, and they are usually cheaper and easier to find. Lithium-ion batteries are the newer type of battery, and they tend to be more expensive.

Third, you’ll need to have the right tools for the job. A socket wrench and a ratchet are usually all you need to remove an old battery and install a new one.

If you were to start with the positive terminal, you could create a spark that could potentially ignite any fumes that might be present.
