If you own a car, then you will have to disconnect the battery for a variety of reasons ranging from simple car maintenance to full engine repairs. Although disconnecting a battery seems intimidating, the process is incredibly simple and can be done in less than a minute once you follow the steps we have provided below.
Steps On How To Disconnect a Car Battery:
-Take necessary precautions before you start disconnecting battery: Batteries hold a potentially lethal electrical charge and even contain corrosive agents that can produce a flammable gas. So, before removing a car battery, turn off the ignition and also wear safety goggles and gloves to protect your eyes and hands.
-Locate the negative & Positive terminals: Find the negative terminal on the top of your car’s battery. This usually has a black cover and the battery itself may have a minus sign near the connector post. Likewise, the positive terminal usually has a red cap or a plus sign on the battery near its connection post.
-Disconnect the negative terminal first: You will need to first loosen the nut on the negative terminal. Always work on the negative-terminal before the positive-terminal when disconnecting your battery. So, grab a socket from your socket kit and hold it near but not against the nut on the negative terminal of your battery. Put the wrench on the nut on the negative terminal and turn counterclockwise. It will take only a few turns to loosen the nut. Afterwards, pull the negative connector from the battery after you’ve loosened the nut. Push it aside so it is unable to make contact with the battery while you’re doing your work.
-Disconnect the positive terminal: After removing the positive-terminal, don’t let the positive connector touch any metal part of the car. This because there is a residual current in the system that if it were to touch a metal surface then it could disrupt or damage the circuits in the vehicle.
-Continue with your maintenance work: After disconnecting your battery-terminals, you can safely perform repairs on electrical components of the vehicle. Likewise, if you need to put in a new car battery then you should unscrew the brackets that hold the battery-tray, lift the old-battery straight up & out of its tray, place the new battery on the tray and tighten the clamps. Finish by connecting the cable for the positive terminal first then the negative last. Remember to securely tighten the nuts on each terminal.
