you could have a short some where causing it to drain the battery. or the hatch or doors are not shut keeping the lights on in the car.
Yes...it will not have the same capacity afterwards. Yes. Everytime you run an auto battery down completely you shorten the life of the battery. It is not designed to be run flat as a deep cell battery is.
I had the same problem with my 2000 eclipse gt. You are probably still running the factory battery and after time, the battery losses its cold crank amps. It still holds a good charge, hence the reason all of your electronics work well, but the battery does not have enough amps to turn the engine over. Simply replace the battery and you'll be starting everytime. After changing the battery, I suggest starting the car and letting it idle for fifteen minutes to allow the computer to "re-learn" its proper air:fuel ratio.
On a modern car no. Older completely, mechanical vehicles will run without a battery after starting because everything is driven from the motor or vacuum lines. Cars with electronic ignition and fuel injection and electric fuel pumps need a battery to give a consistent voltage. The alternator provides electric power to recharge the battery but the power output follows the rmp of the motor.
could be a dead cell in battery if battery ic over 4 yeare old is probably battery
Have you checked you alternator?
Start with checking the battery terminals for corrosion, then the wires going to the starter. Be sure everything is clean and tight. Also have the battery checked
It depends on the type of battery, and the capacity of the battery, and the application you are using the battery for.
It could be as simple as a corroded battery terminal. Remove both battery terminals and clean them then see if it makes any difference. BTW, when a battery starts to corrode terminals it usually means that it's starting to vent some battery acid during the charge cycle. That's a sign that the battery is getting ready to go bad. It's probably still ok for now, but be ready for it to go out on you.
If you use the radio without the engine running you will eventually discharge the power from the battery. It should be fine for a couple of hours, If not, your battery may need replacing.
There is a switch on the clutch pedal that keeps you from starting the car in gear and killing someone. You should use your clutch anyways. Saves wear and tear on the starter and battery
I am having the same issues with a 1995 ford taurus. I think I have traced it to the solenoid. When the car doesn't start, I simply pop the hood, take the negative cable off the battery for a few seconds and replace it. The car has started everytime when I have done this. I am going to be replacing the solenoid this weekend to see if it fixes the issue.
Waiting for the battery to drain completely to extend battery life.
