Leaving the keys in the ignition can drain the battery, eventually killing it. This happens due to the constant flow of electricity, which can overheat the ignition coil and cause it to fail over time. If the ignition is left in the ACC position, the battery will drain even faster.
How long can you leave car in on position before battery dies?
Typically, your car can sit about four weeks to two months without driving before the battery dies. The reason your car can sit only for so long before it dies is the fact that your car battery is in use even when you’re not behind the wheel.
Does car battery charge while ignition on?
The simple answer to this question is yes, your car’s battery will start to charge as long as your engine is running. As long as the electrical systems aren’t draining the battery quicker than the alternator is charging it, it is technically possible to completely charge your battery using this method.
How long can a car sit in accessory mode?
Typically about 30 to 45 minutes depending upon what you have running including the radio, the fan blower, the lights (cabin or otherwise), etc.
Will leaving ignition on drain battery? – Related Questions
Will accessory mode drain my car battery?
Turning the key to the “accessory” position doesn’t actually draw any electricity from the battery. It simply allows you to draw a limited amount of electricity to run certain accessories, like the radio, the power windows and the interior lights.
Does leaving the radio on drain car battery?
Leaving a car radio on can drain the battery life from your vehicle. However, how long it takes for that to actually happen will depend on your car’s sound system and how much power it uses. Car radios generally don’t require a lot of power, but they do use some.
Does accessory use petrol?
Yes, cars use extra petrol (gas) to provide the energy for the AC and all the electrical accessories. The AC compressor is powered directly from the engine and so can only be in use when the engine is running.
How do I keep the radio on at the drive in?
Procedure is: Turn off car. Press and hold power button for 10 or 11 seconds until the car beeps twice.
How do I get my car out of accessory mode?

What does battery discharging when stationary mean?
When the battery charge level increases the power requirements to charge the battery will decrease. So, if the alternator produces 28 Amp only and the car needs 50 Amp, the battery discharging while stationary would pop up.
Why does battery discharge?
Whenever a load is connected to the battery, it draws current from the battery, resulting in battery discharge. Battery discharge could be understood to be a phenomenon in which the battery gets depleted of its charge. Greater the current drawn by the load, faster the battery discharges.
What kills a car battery?

What temperature kills a car battery?
While the car is running, the alternator recharges the battery so it can start your car the next time. But car batteries lose power when temperatures drop below 32°F (0°C), and some can even lose half their power when the temperature drops below 0°F (-18°C).
Can an alternator drain a battery when the car is off?
A corroded or defective alternator diode will faultily continue charging the circuit even when the car off. This, in turn, will drain your car battery and cause the car not to start.
How do I know if my battery is bad or my alternator?
If your engine won’t turn over or takes far longer than usual, it’s time to grab the jumper cables and attempt a jump-start. If your engine starts and stays running but won’t start again later, it’s likely a battery problem. If your vehicle immediately stalls, it’s probably a bad alternator.
How do you know if its the alternator or battery?
Jumpstart your car. If you can turn the engine on, but it dies shortly thereafter, your car alternator likely isn’t able to charge the battery. On the other hand, if you jumpstart the car and later on it fails to start on its own, it’s likely a dead battery.
