Can Leaving Ignition On Overnight Cause Damage or Battery Drain? - Władek's Inquiry

Hello.
I have a question:
After switching on the ignition (key in the position before starting,
the lights are on) you can leave the ignition switch on for a longer time period of time ,
eg: for the whole night?
Can I damage something this way?
Does this affect battery consumption and to what extent?

Greetings,

I don't know your car because you didn't confess. Leaving the key in this position powers all the car's basic electrical systems. In the classic system, i.e. the carburetor and conventional ignition system. you can cook for example by autom. suction, discharge the battery through the ignition coil, etc. I do not know what you need these messages for, but one thing I can say is that leaving the keys in the car is not healthy in itself.

The battery would probably be discharged after returning to the car in the morning. However, motor accessories and systems draw some electricity. If it is an engine without electronics, you will probably burn the ignition coil. Well, unless the circuit breaker goes to the open position. And when there is electronics, it is very possible that when the battery "sits down" it will go stupid and, for example, the "check engine" light will light up

Which car. Which year. What engine. To charge the phone?

The car is an Opel Astra II 1.6 8V from 1999. There is some electronics. The sense of the question is related to the use of the cigarette lighter socket (it only has electricity when the ignition is turned on) to charge the phone and use other devices, e.g. mini TV.

Thanks for the tips,

I haven't sat in ASTRA for a long time but something does not suit me. Is it really necessary to put the ignition switch on and not the first one from off to power the socket? And finally, I admire the idea of leaving the car with the keys in the ignition and a pile of equipment that attracts amors of someone else's property. I already understand why some people are bothered by the buzzer in this situation. But as part of the advice if it is absolutely necessary, I suggest powering the socket outside the ignition switch (even through a diode)

Enter the harvester's chest and switch the power on.

in my car, multi-point injection and a pile of electrics
leaving the key in the ignition position will drain the battery very quickly

In most cars, charging a cell phone or listening to the radio while stationary for a long time will discharge the battery, such things should be done for no longer than 2 hours.

The battery in the car is a device designed mainly for starting, such a long-term consumption of current in one direction does not serve it (e.g. attempts to use a car electric drive to drive a boat end up badly (sulphation, capacity drop, etc.). Irrational idea, leaving the cell in the vehicle this is another threat - a tasty morsel for a bum - you can lose a glass and a cell phone

Do I mean that only the battery will suffer? And what about the ignition module, can I damage it? How much in your opinion can I safely leave the ignition switch in this position (i.e. with the ignition on). year.

Best regards and thanks for the comments so far

Ignition coil is smoking on older cars. Nothing should happen here, except the mentioned (harmful) discharge of the battery. I still don't see a rational need to leave the ignition on in a car after driving. Sometimes, when I wanted to use the air-conditioning to the end, I would leave it, for example, standing in front of the railway crossing, turned on for a moment, but it was only 1-2 minutes at most. And with the case of the discharge I met after playing the radio for an hour (children on the plot) and only meatball. 100% electrified car - fuel pump, windows, alarms. it will not get clogged because the pump does not provide fuel, the same in the hall. And towing a vehicle with the windows steamed up is fun.

I share my opinion, I had such a case, the coil got hot, but I turned off the ignition immediately and it survived.

So what time would you consider safe? Besides, I wonder why the manufacturer has solved it in such a way that I have to have the ignition on to have electricity in the cigarette lighter socket. Because this input also provides for connecting other devices, so if turning on the ignition, there should be some protection against damage to other devices layouts etc.

And you did not check if by any chance the key in position 0 is not enough (i.e. the release of the steering lock lock). In Matiza, the cigarette lighter socket is also not energized all the time (it appears only in position 0 or I).

If the manufacturer considered it intentional to use the battery at a standstill, he would construct it this way. Only the hazard lights and parking lights, with awareness of the possibility of damage, are turned on without a key.
But these are not normal situations. In my case, the short and high beam lights go off with the key, even the radio turns off after 30 minutes when left without the key. So such consumption and time is considered acceptable by the VW Passat manufacturer.

And if you do not intend to do so, you can make a different socket, cables connected to the battery with some "frogs" necessarily with a fuse so that something does not catch fire (2 amps is enough) and already.
Just be careful, don't confuse + and -.

Watching a mini TV at a picnic is just right. And phones, you can charge a lot not only your own but also the whole family, electricity is surely enough.
With higher energy consumption, you need to control the battery voltage so that your Astra can be fired.
