My friend also has a Mustang GT and he says if you have the battery to your mustang on for too long(like listening to music without the engine running) and your not able to start the engine, but the battery still works for the lights on your car and radio etc.... If you turn the car completely off and wait for an hour or so. The battery charges itself back and you can start your engine again. Is this true or would you have to get a jump start?

why do that anyway

?? Were just having a friendly argument and think were both right. It may seem dumb to do, but is it right?

I dont know but for all the time I parked in the back woods with what's her name, I never ran the battery out listening to music...

prolly 50/50 chance... sometimes it will sometimes it wont there are too many variables

If you kill the battery, you will need a jump. The battery will charge itself only a small amount due to the way the lead plates inside the battery are configured. In short, if you kill it, dont count on it charging backup.

i believe that the battery only charges itself back when the engine is on. Normally when I get a jumpstart, I am always suggested to leave the car in idle and leave the engine running for a few minutes to charge back the battery... =D

See i know if u completely kill the battery it wont start, but what if the battery is still partly charged cause it can still play the music and have the lights on and what not...

how did this argument start?

"hey brandman guess what, if u leave ur music on ur batter runs out forever!" "omg no it doesnt it recharges!!"

Lol no, he said he was working on the inside of his car working on some mod and said after like an hour he finished and when he went to start the car, it wouldn't start. He then said like after an hour he went to start it again and it actually worked. Thats why I said this was impossible.
