Will your car battery die if you leave the door open?
This is probably the most well-known cause of total battery drainage. Even just leaving a door slightly ajar may be enough to cause the internal lights to illuminate – and if you leave your lights on long enough, your car’s battery will be drained.
How long does it take for a car battery to die with door open?
Depends on the car. Usually if the door is left open, the lights will turn off after about five minutes. My previous two cars would do that, but the suspension pump would remain active if a door was open, after a few hours that would flatten the battery.
Is there a 12 volt battery disconnect switch?
But a 12 volt battery disconnect switch saves you the hassle. Instead of removing the battery, you can just disconnect the switch. When your RV is in storage for a long time and you have accidentally left a light on in a compartment or anything inside, your house batteries do not get drained with the RV battery disconnect switch on.
Why is my glove box light draining the battery?
Inspect the glove box light, in most cases this light is controlled by a small pin switch inside the box door frame. If this switch malfunctions or is misaligned it will allow the light to stay on draining the battery.
What happens if you leave the battery plugged in for too long?
Most converters do not have this capability unless you have a very expensive 2000 watt inverter or take the batteries out and use a professional multi-stage charger! Just leaving it plugged in does nothing more than topping them off and letting sulphur collect on the plates and limit the amount of energy storage.
What causes the side view mirror to draw the battery down?
This will force the lock actuator in the door to stay on which will draw the battery down. Inspect the lock switch to make sure it returns to its neutral position. If this switch is broken or permanently stuck replacement is required. The side view mirror switch continues to get power after the ignition switch is off.
