What are the components of a car battery?

Can a bad car battery cause a running car to die even if the alternator is good?

  • While trying to start my car one day I found that the battery appeared completely dead and the car would not start and no electronics would come on. I had someone jumpstart the car and it ran fine for about 10 minutes and then died completely again. During this 10 minutes the inside lights were flickering. I figured that the alternator was bad, but after trying a new battery first the car seems to be running fine. I was wondering if a bad battery can cause a car that is running to die even if the alternator and other electrical components are fine.

  • Answer:

    Yes that can cause your car to not run. The alternator helps the battery charge up and keeps the car running. If the battery is dead it is working harder to try and charge it when all it is doing is working for nothing. With the new battery in the alternator has something to charge so there for it will stay running.

I'm still thinking your alternater is bad, and the new battery is disguising the problem for awhile.

yes. when u start the car youre batery is what turns it on when u turn the key. when ur driving the batery probably died again because it was a bad charge.

Im sure you have already been told but, you have a bad altenator...the reason it ran fine with the new batt was cause the car was useing the new batt for its sourse of power, when it is gone the car will die again...

I just spent $200 on a new alternator only to find out it was a bad battery. I replaced the battery, about 50 bucks, and the vehicle runs like new. So, simple answer to you question - yes.

yes a dead battery is too much for an alternator your dead batt.will draw everything down you need a little charge in the battery or wait for the car to charge the battery with no lights and misc. on

Yup. Some alternators(not all) require battery juice for the alternator to produce juice.

No. The battery is used to start the engine. Once the engine is running, the alternator or generator run the electricity. It may be the alternator going bad. The only other part I can think of would be the coil, when it goes, a running car shuts down. A new battery will work for a little while as long as you turn on no lights, radio or any elec. Once you do, if it shuts down again, your coil is shot. Sky
