We can avoid the annoying dead car battery. To prevent and help the dead car battery, we must know the causes for it. So, put aside the jumper cables and check for the things that can drain your car battery.

What Can Drain Your Car Battery?

1. You left the headlights on

One of the first things is to check are your headlights to see if your car battery is draining. Many new vehicles have designed headlights to stay on and will turn off after a certain amount of time automatically. If your car battery doesn’t have this feature, then your headlights may be on until you turn them off or until the car battery is completely drained.

2. By parasitic draw

Even when the car is off, your battery powers the clock, radio, or alarm system. These things should not have a major impact, but the interior lights, door lights, or bad fuses have a major impact that causes battery drain.

While your engine runs, the alternator recharges the battery so there will be no tension on the battery. When the engine is not running, the the alternator isn’t recharging the battery. Electrical mishaps so occur therefore to avoid battery drain, make sure all the lights are turned off, doors closed to avoid a parasitic draw.

 

3. Battery connections are loose or corroded

Check your battery positive and negative terminals because sometimes they may lose the connections. These battery terminals may also become corroded. If your battery terminals get loose or corroded, the vehicle wouldn’t start properly and may give trouble because the battery doesn’t transmit the power supply. To prevent corrosion-related problems, follow the maintenance tips of a car battery. 

4. It’s extremely cold

Freezing winter days can cause problems for your car battery. Some  batteries have a high tendency to have more resistance to extreme temperatures. But if your battery is weak and intense cold could weaken its performance more, so in this case, you can contact a mechanic. Auto expert technicians will help diagnose and troubleshoot the issue. This is one of the common reasons that can drain your car battery.

5. Battery isn’t charging

Your car is dependent on your battery when you fire up the engine, but once the vehicle starts running, the battery is dependent on the alternator to stay charged. If your alternator isn’t working correctly, then the power is not transmitted to the battery, and the vehicle gets into trouble during driving. 

6. Short Drives

During short drives, your alternator doesn’t get enough time to recharge the battery while running. Frequent short trips can damage the car battery’s life span. But nowadays, batteries are coming up with high cranking power. It’s feasible to purchase high cranking power batteries.

7. Battery is old

If your car battery dies even after the jumpstart, then it’s time for a replacement. Frequent short drives, extreme temperatures can shorten the life span of the battery to 2-3 years. These are simple reasons that can drain your car battery. Make sure to check all these things and go for a replacement.
