Can an automobile battery be recharged just by driving it a long distance?
Yes, if the alternator is functioning and you are not loading the charging circuit (using as much charge as the alternator is putting out so the battery receives nothing). Please note that "Idling" to charge the alternator normally does not work as the alternator is not turning fast enough to charge the battery, it only maintains the status quo for energy usage.
Does alternator need to charge after replacing it?

Can a bad compressor effect the alternator or battery?
In most cases the air conditioner does not affect the battery or the alternator unless you are running it than yes, any pull on the electrical system such as a bad compressor that has been turned on for any period of time could more than likely drain a battery. Its not likely that it would kill the alternator or the battery, it is more then likely that if you find your alternator is dead and does not work it was on its way out anyway. But, by turning a bad compressor on you force the brushes and the armature to exert themselves causing them to burn out faster.
How do you know when alternator is bad?

If the car turns off then your alternator is bad. If the car remains in then alternator is good and possible bad battery. Hope this helps
How do you know your alternator is going bad in Lexus gs400?
Hello, There are many symptoms of a bad alternator that you should pay attention to: If your alternator is not working properly it might affect how the alternator belt is turning. An alternator that is not working properly will make an audible sound. Removing the alternator belt can confirm if noise is coming from the alternator. Another symptom is if anything electrical slows (windows, seats, etc) or the lights dim while you are driving. Yet another symptom is experiencing difficulties starting your car. This could be an issue with the battery, so make sure that you check the terminals and note the age of the battery. If your battery frequently discharges then this is another sign of a bad alternator. Hope this helps!
