RE: Dead Battery Syndrome- WTF...?!
If anyone suspects that there is an unusually high drain on the battery when the vehicle is off, you could try putting a DVOM with an amp/current readability in line with the neg. post of the battery and the negative cable (Disconnected from the battery, of course) and see what it reads. There will be some draw for things like computer memory etc, but it should be in the milliamp range. That is normal. But if you see a draw that approaches the sort of draw that a dome light would draw, then you have a problem.
If you should do this test, whatever you do, don't try to start the vehicle with the DVOM connected orthe DVOMwill be FUBAR.

I'm not sure about the Shaker system being a drain on the battery. Although, I have read that on here several times. I know it's not true on my personal car.
I have the Shaker 1000 and leave it all on the time before turning off the car. It hasn't caused a dead battery, in the 31 months I've owned the Mustang.
My car is rarely driven, too. Probably two days out of the the month. I've put about 9,600 miles on it since I purchased it new the first week in January 2006 and only 2,300 miles in the last year. I average about 300 miles per month.

RE: Weird problem: battery o.k. but wouldn't start (alarm!)
ORIGINAL: GT Newbie
Yep, you're right- that is just a "charging" gauge (bummer!).
The dealer explained that to me this afternoon when I dropped by.
They told me the battery was dead and defective and put in a new (better!) one, but want to keep her there till they find out exactly why she died (just defective, or perhaps a short somewhere that was draining power?) so that it doesn't happen again!
I'll let you folks know the verdict as soon as they tell me.
Long live my warranty!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
P.S. I did try to jump-start it but it didn't work at all, but they jump-started it at the dealers the next morning and it did for them.
I'm hopeless when it comes to fixing anything myself- but at least I know it, and that keeps me from breaking **** and leaving repairs to those more qualified (which is just about everyone on the planet...).

Yea, that is the charging gauge, not a battery gauge. I know there is a problem with our cars and the battery draining if left unused to a time. They have a "battery saver" on the cars now, what ever that is. Sounds like the battery, but why could you not "jump" start it? Would Love to know that the dealer says.

Have you been running the car on the highway? If you are just driving around town with headlights, wipers, and climate control on, you are not giving the alternator a chance to fully charge the battery.
If you are into DIY to some extent, see that the battery cable terminals are attached to the battery posts firmly, and that there is no corrosion. If you have a voltmeter, see what the voltage is when charging (generally around 13.5 volts at idle) and what it is with the engine off after the car has sat overnight (should be around 12.65 volts.)
Good luck.

edit: btw, nice dead thread revival
x2 for me. I can hear the speakers making a weird tone when I sit in it after killing the motor. almost sounds like feedback.
my battery can and will go dead in a few days if I don't physically kill the radio using the pushbutton.
has never killed the battery when the radio is turned off prior to sitting for awhile.
IIf I turn the radio off, it can sit for weeks. The Shaker radio is not turning off the door sub amps. After the first time this ever happened, I paid close attention, and could actually hear very faint noise coming from the speakers after turning off the car and leaving the radio on. It's the radio. Some exhibit it, some don't.
