i left my stereo on and my battery died i jumped it drove for about 15 minutes thinking it would be charged back and it wouldn't start again. What is wrong the alternator is charging the battery and all the wires are fine is my battery going bad?

 

if you totally discharged the battery you will most likely have to put it on a charger for a couple of hours.

 

i am hoping that is all that it is. It started fine when jumped but i'm guessing i have to re charge the battery fully with a charger for it to start without being jumped?

 

yes sir

 

The alternator on these cherokees arent the best, they cannot handle charging a dead battery and running all the vehicles electronics. So you will need to charge it.

 

Also depending on the age of the battery, a complete discharge will kill it standard batteries are not designed to be deep cycled so its hard on even a newer battery, like everyone said hook it up to a charger, if possible hook it it to a trickle charger overnight (2 amps)
