its not the battery. turn the car on...take the battery out while the car is on. It will stay on if your alternator is good. then try to rev the engine. It has to be your alternator.

NOT a good idea....this can lead to a severe voltage spike in your car's electrical sys (think about it- you're removing the primary load...).....

naaa kant be...dats the only effective way in my opinion to see if your alternator is good. unplug the battery while the car is running, if the car stays running, and u can rev it...ur alternator is good.

once again, completely false. i test automotive electrical systems for a living, that very test is the most destructive test we do.....
