Disconnecting the battery doesn’t take long, and it only takes two tools — a wrench and safety gloves (recommended). Here’s how to disconnect your car battery safely and correctly.

When To Disconnect A Car Battery?
To perform some maintenance on your vehicle.
If you are having work done on your vehicle that requires removing or unhooking your battery, it’s a good idea to know how to disconnect it properly. Failing to disconnect a car battery can cause permanent damage to both your car and yourself. The process is simple but will vary slightly depending on whether you have an older or newer model car. You can find detailed instructions online that tell you exactly what tools and supplies you need, so consult these first if possible.
To replace the battery.
A dead car battery is a common problem, but it’s not one you should ignore for too long. If your car doesn’t start, you may need to replace your battery or have some electrical issues fixed at a shop. It’s best to get a new battery from an auto parts store rather than relying on old ones that might be past their prime. Be sure to follow all instructions for installing and charging your new one, as well as for disconnecting and disposing of your old one properly.
Guide To Disconnecting A Car Battery
This guide is to assist you in disconnecting a car battery safely. Improperly disconnecting a car battery can result in severe injuries or damage to your vehicle. Before beginning, be sure to wear rubber gloves and eye protection. You should also have plenty of ventilation available as well as an emergency glass of water in case you swallow any chemicals. The floor should be covered with cardboard or another non-conductive material if possible.
Turning The Ignition Off
Before you disconnect your battery, turn off your ignition and remove the key from your car. You don’t want to leave these things on while you’re working under the hood.
Finding Your Car Battery’s Negative Terminal
The first step in disconnecting your car battery is locating it. Typically, you’ll find it beneath your car’s hood. Look for a black or grey cylinder with two metal clamps or terminals.
In order to remove the battery, find the terminal. Usually, on top of the battery, the negative terminal has a wire connected to it. One side of the battery is usually marked with a – symbol, whereas the other side, will be marked with a + sign. One side will be black, with a black plastic cap attached to identify it, while the other side will be red, with a red plastic cap.
Loosening The Negative Terminal Nut
Take off the plastic caps, and use a wrench that is the right size for the nuts and bolts of your battery terminals.
After loosening the nut, pull the negative connector cable from the battery and push it away, ensuring that it is no longer near the battery again until you are ready.
Repeating With The Positive Terminal
This next step can be really tedious. Once you remove the negative connector, repeat the same process for the positive connector. However, before doing so, make sure you give it a really good push and move it out of the way.
