A bad battery will not hurt an alternator, once the car is running it is relying on the alternator for "juice". However I wouldn't recommend leaving a bad battery in place as it certainly can't be good. The battery just enables you to get the car running. But, a bad alternator will most definitely kill a good battery as it seeks for a source of energy. Subsequently the alternator doesn't charge the battery contrary to popular belief other than a minuscule volt here or there. The alternator would surely blow a battery to high heaven if that were the case. Hope this helps a little. I'm sure someone will chime in if I have gotten anything twisted. Happy motoring

P.S. I like your signature/quote
