While battery drain is less common on modern vehicles than their older counterparts, you may still find yourself wondering, “What could be draining my car battery?” There are several potential reasons, including parasitic draw or improper operation of the lighting system. The technicians at Mercedes-Benz of Silver Spring share information about common car battery drainage causes.
Keeping Your Lights On
The reason why your car battery is drained could be as simple as leaving your lights on. Car lights drain juice from your battery when the vehicle is off, eventually causing it to die. Make sure to turn all your lights off before exiting the car; modern vehicles will remind you to do so.
Parasitic Draw
Parasitic draw refers to an electrical device that drains power from your battery even when your car is turned off. If one of your car’s electronics is drawing too much power, our service team can adjust the electrical wiring and relays to ensure that everything shuts off correctly after you take the key out.
Bad Connections
Electricity could be lost if one or more of your connections is faulty or disconnected. Any wires or contact points that aren’t working right could cause you to lose charge.
Broken Alternator
Your alternator helps recharge your battery after the engine is turned over. A faulty alternator can prevent your battery from properly recharging, so it should be inspected immediately.
Extreme Weather
Keeping your battery out of use in extreme cold or heat can sap electricity from the load cell. High and low temperatures can negatively affect your battery, which you can mitigate by turning it on regularly during extreme weather events.
