Many people who have owned their vehicles for a long time know the sensation of turning the key in the ignition only to be met with silence. Once in awhile, the reason for this scenario that causes a sinking in the gut is a used up starter, but most of the time it is simply a dead battery. It is no secret that we should preventively change our car battery before it dies, but we tend to ignore this advice. If the battery is allowed to die, however, there is no need to fret, because to change a car battery that has stopped working is really quite simple and often does not require calling a mechanic.
Once you pop the hood, or bonnet as it is also called, find the battery. You will likely find it in either of the front corners of the engine bay on the passenger side or the driver side. There will be a small, rubber cover that shields one of the battery terminals. A black cover blankets the negative post, while a red one blankets the positive post. Pull the cover back and begin loosening the screw that secures the battery lug to the terminal found on the battery. Battery lugs are metal clamps at the end of the battery cables that form a connection to the battery terminals.
After the screw is loose on one lug, repeat the procedure on the other. It is important that you do not remove the screw, but loosen it only enough to get the lug off the post. After the screw has come out far enough, place the head of the screwdriver under the lug and pry it upward to lift it from the terminal. Do this for each post. Now you should find the bolts that hold the plastic brace in place over the battery and remove them all the way.
Upon removing these long bolts from the brace, it can then be taken from off of the battery. Now, the dead battery is able to be removed and the new one placed in the reservoir vacated by the old one. Place the brace back over the battery and screw it tightly back into place. Place the battery lugs once more over the terminal posts and tighten the screws snugly enough to create a solid connection. Be careful not to break the lugs. Lower the rubber cover back over its designated terminal and you have completed the task.
There is no need to get uptight over a dead car battery. It is not hard to change a car battery that has stopped working, something that you can do on your own. There is no need to get the professionals involved, and that will greatly ease the burden on your wallet.
