Time. Auto batteries share one thing in common with humans - no matter how long they go on, they all die eventually. they last longer if well maintained, and with a good alternator, but they all die eventually.
no you cannot kill your alternator by switching your battery from one car to another
No.
sound like you have a bad alternator. it will kill the battery.
Yes, if the negetive battery cable is not connected propperly to the battery, it will ruin the alternator and probably kill your car.
If the alternator is not charging the battery, then it will eventually go dead If the voltage regulator (in the alternator) is defective it will eventually kill the battery Check the alternator with a voltmeter A fully charged battery (without engine running) should read approx. 12.8 volts With engine running should read 13.8-14.2 volts
Kills alternator? don't you mean kills battery? Installing a new alternator without first charging the battery well (2amp for 8hrs) will quite likely burn up a new alternator as well as being hard on the battery.
I have heard the alternator does it,cold drains the battery too,if it's not started for awhile can kill it.
The battery is constantly being charged by the alternator as long as the engine is running. The alternator is driven by a fan belt or serpentine belt and provides a consistent steady flow of direct current of around 14 or 15 volts. The amount of voltage is kept steady even at varying engine revolutions by a voltage regulator.
Two things can happen. 1. the voltage regulator fails so that the alternator doesn't know the battery charge is dropping therefore the battery doesn't get charged. 2. The voltage regulator fails in such a way as to allow the alternator to overcharge the battery which causes the battery to overheat and fail, Sometimes an overcharged battery can explode.
Rather than assume, why not check the alternator? If an alternator is not functioning properly, the battery can only remain fully charged if the alternator replaces the electrical energy that has been used. Test the system to determine if there is an electrical drain, but start with the alternator first.
Its a good possibility Your diodes are burnt out, its time to replace your alternator, i had a similar problem on a 95 lumina with a 3.1l motor
Repeated discharging of the battery will destroy it. Connecting the cables in reverse will destroy the battery. An alternator that is overcharging will also destroy the battery. Vibration and or dropping the battery will do it no good. Lastly is age. Over time the battery will cease to function.
