It will not turn the engine over or it will not hold a charge. Either way it must be replaced.
your alternator ain't charging your battery or a bad connection draining the battery
Turn car on remove positive battery terminal if car turns off alternator is bad
The battery does not have sufficient voltage to start the car when it's cold. Have the battery checked out. If it still goes click click after running the car for a while, have the alternator checked also. A bad battery will not hold a charge and a bad alternator will not recharge the battery, (That is the reason to have the battery checked first). Make sure the connections at the battery are clean and tight.
When the battery does not start your car as it normally has, or the battery runs down overnight. If you suspect it is bad then have it checked at an auto parts store.
if it does then if your talking about a car your ingine battery or carboreater is bad
Not likely but as alterantor keeps trying to charge a weak battery it may wear out, however as you are not likely to keep a bad battery in the car for so long there should be no damage to alternator if battery is replaced.
Bad battery, Faulty engine, poorly maintained vehicles, the list goes on and on.
Turn on any light in the car, if the light gets very dim or goes out you have a bad (or discharged) battery. Its remotely possible that the terminal connections on the battery are corroded or dirty.
When the alternator goes bad or goes out completely, the car's battery will be drained. I suggest you pull the alternator and have it tested. If the alternator is bad, you will most likely need a new battery as well. The cost is around $200.00.
Probably a bad ground from the battery to engine/body.
Car batteries get re-charged by the alternator. If your battery recently went dead, "miles" is not what is measured to recharge the battery, "time" is used. I'd leave the car running for 15-30 minutes. Driving for this amount of time too is fine. If the battery goes dead again, probably a bad battery or bad alternator, or sometimes a bad alternator makes the battery go bad and they both need repaired. (typically a new alternator is $120 - $200)
Your battery charge will get so low eventually car won't start and you will get stuck somewhere.
