Cars have what is called ignition off draw. The computers, radio, etc all pull some power to keep there internal memory alive. The normal amount is under .035 amp, which would take 1 to 2 weeks to drain a battery.
Bad Battery. Bad Alternator. Lights left on by mistake. Something left running. Exc.
Dead cell in the battery or the ignition or lights were left on.
Pressing the button on an iBook's battery will illuminate a string of lights; the number of lights illuminated indicates how much charge is left in the battery.
if the battery is in good condition and the lights are standard then 3 hours might be enough so it will not be able to restart itself but this may vary according to battery size condition and lights wattage.
yes it will
Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.
Hazard Light versus Dead BatteryNO, IF the battery is truly dead, then the hazard lights will not work.However, if there is some power left in the battery, even though the voltage may be extremely low, then the hazard lights maycontinue to work.
Lights on. Door wasn't closed all the way which left inside lights on
That's not a design feature, that's a flaw! When the lights are turned on, they draw power from the battery. If your engine isn't running to allow the alternator to charge the battery, then sooner or later the lights will use up all the stored power in your battery. simples.
The battery stores just so much electricity. The lights use this electricity. Sooner or later the supply is depleted.
No but your battery will die so i don't recommend you doing that.
Because you left the lights on all night. This drains the battery. Connect a battery charger and wait about 3 hours. Then the car might start. If it does not start buy a new battery or a new car whichever you prefer.battery juice is gone.
