No, because after the car is started, even in traffic, your alternator is putting out the voltage, and that voltage is controlled by the voltage regulator. What Will be affected is your gas mileage/.

Should your car stay running when you take the pos battery termanal off?
A battery is used to start a car. Once it is running, the alternator then supplies electrical energy to charge the battery as well as power the electrical systems in the car. Removing the battery while the car is running will not affect the running of the car.
Does the battery charger drain the car battery before it recharge it or does the charger builds-up the car battery from where it is initially.?
A battery charger does one thing. It charges a battery, and starts with whatever charge is in the battery and goes from there. Running an automobile battery down will shorten it's life.
Does a car have to be moving to charge the battery?
No , for the battery to be charged the engine must be running . This means that your alternator , if it's functioning properly , is charging the car's battery as the engine is on/running .
How much power does the battery have to have in it when the car is running in a ford E350 2004?
You should read from 13.5 to 14 volts at the battery when the car is running.
Will a car running hot cause battery to die?
No, that will have no effect on the battery.
How long will your car battery last?
I recently had a car battery replaced. They last for maybe 5 to 6 years or so but always remember to never run aircondisioning without starting your engine (if you run the aircondisioning on the battery it reduces its life) In addition, running the battery down will shorten it's life.
If the car battery dies because the door was left ajar will just boosting the battery and running the car be enough or do you need a new battery?
It should come back after running the engine if the battery is good.
Can you charge a dead battery by getting a second car that is running take the good battery out of the running car and put the dead battery into the running car as a means of charging it?
No, this will place a very heavy load on the alternator of the car and may result in burning out the diodes of the car charging the battery. You could easily ruin the alternator. Purchase a battery charger and charge the dead battery with that. Alternators are not made to charge dead batteries.
What will ruin a car battery?
Leaving something on (like headlights) for an extended amount of time without the engine running will shorten the life span of the battery unless the battery is the deep cycle type. Overcharging an automotive battery will also shorten its life span.
Does an alternator charge a battery while the car is not running?
No , just when the engine is running
If the battery is going out will the alternator still power the car?
the battery job is to start the car so the alternator will kick in after the car is running
Can you charge a dead car battery that is disconnected from the car with another running car?
yes
