A dead battery means your car won’t start – making the headlights dim and the engine unresponsive.
It can be a real trouble should it drop dead in the middle of nowhere or in a morning when you are already late for work.
What drains a car battery? Are you curious about what the reasons might be?
What Can Drain A Car Battery?
Many of us wonder what causes car battery to drain. Contrary to popular belief, there are quite a few things that can happen which lead to drained batteries even if you already equipped the best rated car batteries.
Read on, and learn about the 6 most common reasons that may suck the juice of your car battery.
1. Keeping The Lights On
Keeping the lights on is one of the reasons what kills a car battery. It’s a mistake that every driver has made at least once in their lifetime as they ask more than one time “what could be draining my car battery”.
You have come from work really tired and rushed to the home leaving the headlights on or the trunk open, making the battery to drain overnight.
Even the small dome lights can drain the car battery dramatically. Or after packing your car at home, you forget the light so the car battery drains overnight.
So, make sure you haven’t left any lights on before closing the door behind you.
2. Electrical Problems
If someone asks you the question of “what drains a car battery when the car is off?”.
Electrical problems are the answer you should bear in mind. Even if you turn the ignition key off, some functions still keep running. It’s normal for the security alarm, clock, and radio presets to be operational all the time.
However, some other components might be switched on if there’s an electrical glitch. For example, the parasitic drain could extend to turning on the trunk and glove box lights, which typically remain off.
3. The Battery Is In Weak Condition
Poor maintenance can leave a battery in a fragile condition, so it may not retain power for a long time and it is what causes a car battery to die quickly.
It will be vulnerable to every condition. Even small drains like the clock or the radio’s memory function can leave it dead.
Besides, such a battery doesn’t fare well in extremely hot or cold weather. So, take care of it if you don’t want to deal with a dead car in the morning.
