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.
The "electrical pressure" probably refers to the voltage. This is usually provided by a battery. The battery is recharged by the engine when it is running.
The alternator is run by a belt connected to the engine. When the engine is running the alternator is turning. The alternator is what produces the electrical current that charges the battery & powers everything electrical while the engine is running. the battery is mainly to start the engine.
to crank the engine and then function as a capacitor for unused electrical energy when the alternator is running

Have you checked the alternator?
Check to see if the alternator is working Connect a voltmeter to battery: Without engine running reading should be about 12.8 With engine running reading should be 13.8-14.2 If not bad alternator
Yes, the alternator provides electrical energy to keep the battery charged. If the alternator isn't functioning, the battery will discharge and there will be insufficient electrical energy to operate the ignition and other electrical components. Understand that a battery is only an electrical STORAGE device. Electrical energy is produced by the alternator. The function of the battery is to provide electrical energy for NEXT time you want to start the engine. Once the engine is started, the alternator must take care of all electrical requirements of the vehicle as well as for providing enough additional electrical energy to replace electrical energy to the battery that was last used when the engine was started.
Something is discharging the battery when it is not running. Have the electrical system checked.
Check alternator with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running With engine running reading should be approx. 13.8 - 14.2 volts
If the car is on (Ignition is on, engine is running) then no. Nothing should drain the battery when the car is running, there is a device called an alternator with a belt that usually goes around the crankshaft that transforms the mechanical energy into electrical energy. As long as you have the car running, the battery should not die. If so, you have a mechanical problem.
The Battery? No, not typically the battery. That means that the alternator is not charging the battery and IF the engine is running, it's getting all of it's electrical energy from the battery. It means that once the battery charge is depleted, the engine won't run again until you recharge the battery.
A 1995 Ford F150 will start to die after running for about 15 minutes if the fuel or electrical system have a failure. A bad battery or electrical system will also prevent it from restarting.
Why are you disconnecting the battery with the engine running? Never mind, you've probably already figured this out by now, but there's a good chance your alternator is fried and your spark plugs are running on battery power. Get your alternator checked out. New ones aren't that expensive (approx. $50) and can be changed by anyone handy with tools.
If you mean like AA or AAA, nothing. Absolutely nothing happens. If they both have an electrical current running, I don't know, it might be dangerous.
Your putting a charge on the battery when its running.
The battery is an electrical storage device. When everything works properly, the engine turns the alternator, providing energy to that system. The alternator turns that mechanical energy into electrical energy which is used to operate all of the electrical equipment on the vehicle while the engine is running. The alternator also provides electrical energy to the battery, allowing the battery to store the electrical energy for NEXT time you want to start the engine. The starter requires a large amount of electrical energy, which most automotive batteries are capable of providing. After the battery does it's job, providing energy to the starting system, the alternator then takes over, recharging the battery and providing the energy necessary to run everything... but it's all like that ONLY when everything works properly.
First check the battery, have to have more than 12 volts. Next, check the main fuse, it is just beside the battery. Check all cnx around the battery. Start with this.
You need a new battery. They do wear out. The laptop needs electricity to run, either with the electrical cord or with the battery. You cannot "trick" it into thinking it is plugged in any more than you can "trick" a car into running without gasoline or a T.V. into running without electricity.
As long as the battery is charged and electrical component use is kept at a minimum I've seen vehicles drive for a couple of hours before the battery dies. Newer cars with daytime running lights and lots of electrical toys die quicker.
Car alarm in Lexus ES300 started going off at random when car was parked, not running. I changed the key fob battery (flat watch battery) with a new battery and it fixed the problem.
The alternator is probably over-charging the battery. Replace the alternator if the voltage at the battery terminals is over 15V when the engine is running.
Will a Car Stop Running If the Battery is LowThe answer is yes and no. It depends on HOW low. The electrical computer(s) and ignition systems require a minimum voltage. What that voltage number is I don't know, and it probably varies with various models of vehicles and the amount of accessories on it.
If it is running on the battery only then that means the alternator is not charging the battery.
A light in your car might be on, running down the battery!!
