How long to discharge car battery interior light on

Sometimes when people are tired they forget to turn off the lights or headlights. The next day they wake up and their car won't start because the lights were on.

When you leave the lights on in your car for a long time, it'll make your car's battery empty. This is because the battery will get less energy from being on the move. But if you turn on your headlights or any other lights, then this won't happen. The headlights are getting energy from the battery to work. They usually don't stay on all night and when you come back to check them in the morning, they won't be on anymore!

You might have turned off your car and your lights, but other reasons could cause your lights to stay on even though you’ve turned both off. For example, if you left something plugged in or the light was turned on before you came back – those are a few examples of things that can happen.

  • Leaving your car boot a bit open
  • Not completely closely your car doors

Your car can detect when there is something wrong and fix it. You should be careful to shut your doors all the way or else you might not be able to start your car later on. That would be very frustrating.

What Happens If You Accidentally Leave Your Car Lights On

Batteries need to be recharged. Car batteries can only be recharged when your car is running and the engine is on. When you have left your lights on for too long, go check to see if the battery has enough charge in it. If it does, then you might need a jumpstart but otherwise you will not be able to start your car. 

When the lights in your car are on and the engine is not running, the battery will lose power. This is because the battery tries to keep the lights on. The closer you get to running out of power, the more expensive it will be to fix your car (or tow it). If you do not have an accident coverage plan for this, then all of that money has to come from you and your family's pocket, even if it was just an accident.

Will My Car Battery Die If I Leave My Lights On

Your car battery's life depends on how long you leave it on. How full your car battery is and how new or old it is will determine how long the lights will stay on and how easy it will be to start your car when you switch it on. If your battery is brand new and in good condition, it could last a few hours. But if your battery isn't in good condition, it might not even last an hour. 

The condition of your battery determines a lot. If your car has an old battery that you've probably changed for years, leaving the lights on when the engine isn't running will mean that you might need to get a new battery for your car.

If your car battery is new and in good condition, you can come back from a trip to find that the battery has died. Unlike an old battery, you will not need to buy a new one. You might be able to jumpstart it if you know how or with help from your mechanic and soon you will be driving again! 

Sometimes when people leave their car doors open for too long, the lights stay on for the whole time they are gone. This wastes power and will make your battery die faster. If this happens a few times in a row, it can kill your battery- so make sure that does not happen.

Will A Dead Car Battery Recharge Itself

No, a dead battery cannot recharge itself. You can try charging it or jumpstarting it with another battery or car, but if you leave the lights on, your battery will stay dead. Another way to recharge a battery is by jumpstarting it and then running the engine for a while. 

But if you can't do that, you could take it to a mechanic and they could use special battery chargers to recharge it temporarily. As long as your car is moving, the alternator will keep recharging your battery.


Leaving your car lights on can be an accident. Sometimes you do not know and then the battery will run out of power and die. This will happen faster if you leave the lights on a lot, like all day. The battery will work less well and need to be replaced sooner. You do not want to spend too much money replacing the battery because it can cost a lot.
