the alternator is bad...........battery is fine


If you charge the battery and it still won't crank use a jumper to another car, if your car starts it's very likely your battery is defective. Here's an easy way to check your alternator....with a good voltmeter check the battery voltage with engine stopped and check it again with the engine running ..there should be an increase of 2 to 3 volts with engine running if the alternator is good.
