Changing a car battery is a relatively straightforward task that most car owners can handle themselves. However, it’s important to follow the proper safety precautions and steps to avoid any potential hazards.
Here’s a step-by-step guide on how to change your car battery:
- Gather your materials. You will need a new car battery, a wrench or socket to loosen the battery terminals, a pair of safety glasses, and a pair of insulated gloves.
