The battery is bad or the alternator is not putting out the correct voltage and is bad.
That light doesn't mean that your battery needs to be replaced. It means that your battery is not being charged while the car is running. Have your alternator tested.
It could be a faulty battery, If you have bought a new one recently, and it still wont stay charged, its probably your altenator. good luck or it may be the altenater.
did you find the problem?? i having the same deal with my '06. new battery and alt is fine!
Normally 8-11 hours on a new battery. Depending on which one you have time can vary.
You have a short - it's hard to be more exact than that, but if you disconnect the battery and charge it outside of the car and it stays charged, you have a short. If it does not stay charged, you need a new battery.
Normally, no it should be fully charged if it is a fresh battery.
No, mine is fully charged thank you
it's either your wiring or the wrong alternator or a bad battery !!
It might need a new battery.
Get a new battery, mine was doing the same thing. No matter how charged it is, youll still need a new one.
Your alternator is probably rebuilt and not really new. I have had this problem several times and I have bought a new battery and alternator. The alternator keeps your battery charged and powers your electrical system, so even when driving you can lose all power in the car from the alternator draining your battery. Take the battery and alternator to an auto store and they will test both for free. Ask them about the difference in a rebuilt alternator and a brand new one. This is a very common problem.
