It's probably the alternator. A battery is only an electrical storage device. It stores electrical energy so that the vehicle can be started next time you want to go someplace. If the alternator isn't converting some of the engine's energy into electical energy, the battery ends up running everything until it eventually just runs out of energy. If you test the alternator and find that it's not functioning, a new alternator may be able to put enough of a charge back into your battery so that you can continue to use it. Unfortunately, an older battery will often fail completely once it is allowed to discharge completely. When you "Jump start" the car you are putting a small amount of electrical energy into the battery, just enough to run the vehicle for a few minutes. Next time you get it started, go directly to an auto parts retailer such as Checker, Kragen or Auto Zone, then have them test the alternator for you. If it doesn't work at all, you'll know to replace the alternator and maybe they can even talk you through doing it yourself. It really isn't that difficult for most vehicles.

Your 1997 Mazda 626 will not start after an alternator malfunction why?

Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving. You can test this by jump starting your car with another car and after your car is running you should be able to disconnect your battery and car should still run off the alternator. If your car stops than your alternator is RS. Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving.

Can starting a car recharge a battery?

If the alternator is in good condition, it should provide a charge to the battery while the engine is running and it will recharge if the battery is also in good condition. The act of starting the car actually discharges the battery.

Why would a car be completely dead with no lights electronics or ignition after it was just running fine?

The only thing that comes to mind in a situation where a car that was running a short time ago and now is COMPLETELY DEAD is a failure of the battery or the primary cables/connections. I'd begin by checking the cable connections at the ends on the battery. The ends at the battery are more prone to failure than the other ends, but check both ends of the cables starting at the battery side. One would be wise to do this with caution, or, if lacking sufficient expertise, with some help.

Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.

Why would extreme cold cause a car battery to die when car is not running?

Extreme cold by itself will not cause battery failure. If the battery is discharged for any reason, such as the alternator did not fully charge the battery last time the engine was run, perhaps something was left ON last time the engine was running or possibly even the battery had an internal short, then another condition can enter into the situation. A battery cell can freeze and crack the case if the cell is allowed to completely discharge. Also, if the cell completely discharges then sits for a period of time, the plates in the cell can "sulphate", making them unable to ever take a charge again. Understand that a battery is nothing more than a storage device. It does not MAKE electricity, it only stores what was produced by the alternator.

How do i know if it is the battery or the alternator?

Remove the Negative (black) battery terminal while the vehicle is running and if the vehicle dies then it's the alternator, if it stays running then it's the battery. Although this method isn't guaranteed it's usually accurate. DO NOT REMOVE THE POSITIVE terminal (red) from the battery while it's running. It could cause a spark and make the battery explode. Another way is to drive to Autozone or Advanced Auto and ask them to test it. They'll do it for free.

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.
