How To Clean Car Battery Terminals--THE EASY WAY!!!

Originally recorded June 5, 2014.

This video explains how to clean your car battery terminals. There are a few tools required: A wrench (10mm for this car), and some sort of wire brush or battery terminal cleaning tool.

Simply remove the NEGATIVE battery terminal first, then the positive, and clean both the battery posts and the actual terminals with your wire brush until they are bright and shiny.

Then, reconnect your positive cable first, and negative cable last.

Fairly simple, and should take a novice only about 10 minutes.

Important note: On most modern cars, when the battery has been disconnected, the computer will lose the engine run characteristics. That means that once cleaned and you start the engine back up, it may run funny for a while--too fast or too slow, it make shake, even stall on you. This is especially true if it is an older car (reason being is the computer is expecting the intake to be perfectly clean, but on a car with many miles on it, it isn't clean, so the computer has to compensate, and it takes time for that to happen). Usually after 15 minutes or so the car should be running normally once again.
