Without a working battery, your car will refuse to start. Along with causing starting issues, low battery power can lead to troubles in the many electrical systems of your vehicle. An auto shop that offers Mercedes service in Sacramento can get to the bottom of your battery life problems. After you have received battery repair services from your local auto shop, you will want to be on the lookout for signs that your battery is being drained prematurely. Let’s review three of the most common causes of battery drain in today’s vehicles. 
Illuminated Lights
Most drivers accidentally leave the lights on in their cars at one point or another. Even if your car is equipped with a system that turns off your headlights automatically, your interior lights or trunk lights can also be left on overnight. By leaving your lights on for several hours, you may wind up with a completely drained battery by the time you go to start up your car. To prevent your battery from dying, always remember to shut off all of your car’s lights before you head into your house for the night.
Electrical Problems
Certain electrical components, such as your radio and alarm systems, need to be supplied with a small amount of electricity at all times. However, if any of these systems are experiencing electrical problems, they may start to drain your battery excessively. A certified mechanic can troubleshoot your vehicle’s electrical systems and determine whether they are creating a parasitic drain on your battery.
Alternator Issues
In order for your battery to recharge with power, it must be supplied with fresh charge from your car’s alternator. If your alternator is experiencing troubles, however, the diode may not be able to deliver enough current to recharge your battery. When you notice the signs and symptoms of alternator issues, such as flickering headlights, do not hesitate to schedule a diagnostic appointment with your mechanic. By repairing your alternator, you will be able to safeguard your battery against excessive drain.
