Desert Oasis Auto Repair Audi

For years, Audi has developed some of most praiseworthy vehicles on the market. Whether you own an Audi A4 sedan or an Audi TT sports coupe, you can expect your vehicle to deliver a very entertaining driving experience. If your Audi fails to crank, the most likely source of the problem is a dead battery. Although your Audi’s battery is engineered to last for a very long time, there are certain things that can drain its energy supply. Here are some of the common causes of a dead battery.

Leaving the lights on
Like any other vehicle, the headlights on your Audi demand a great deal of energy. When the engine is running, the alternator can provide the necessary electrical power. However, the headlights must rely on the battery for power when the engine is turned off. If you accidentally leave your lights on for an extended period, you can expect the battery to be very weak, if not completely dead. Although the interior lights do not drain as much power, they can still lead to a dead battery if they are left on overnight.

Radio use
Many Audi owners love to listen to the radio while cleaning their vehicle. This is usually not a problem for the battery. On the other hand, leaving the radio on for hours at a time can cause the battery’s energy levels to plummet.

Air conditioning
Your Audi’s air conditioner demands even more power than the headlights. Fortunately, the alternator is designed to supply the air conditioner with a steady electric current. However, a faulty alternator will force the battery to take on the task of powering the air conditioner. In some instances, this may completely drain the battery in as little as 10 minutes time.

Old battery
A car battery is only designed to last for a certain amount of time, after the battery is manufactured, which is easily identified by the expiration date is stamped on the top of it. If you fail to have your battery replaced in a timely manner, its performance will gradually begin to decline. Extremely hot or cold weather can also have a detrimental impact of the longevity of a car battery.
