Yeah, in my car GT and my sister's the battery went out after almost exactly 2 years. Of course I took it to ford and the replaced it no problem, but still. I drive my car 360 days a year and I would think the batter should last longer than that.

 

I recently took my '06 in for this very problem (dead battery syndrome). Conclusions of the dealer: Battery is fine, no dead cells, etc. They told me it needs to be 'driven more regularly'. I purchased a 'battery tender plus' and now I keep it on the charger if I'm not driving it at least every other day.

 

I moved it to the right forum for you!

 

This is the best advice for the OP as I did the same thing for my 06 GT and no problems since......I know it is not an actual fix but it works....also make sure you turn off the skipper 500 before you leave the vehicle.... I believe for some this was where the current was being drawn from.

 

I've let mine sit for weeks at a time. Once it sat for over 4 weeks. Started up fine.

Another time it died after 4 days.

IMO it had to be due to that problem with the Shaker 500. That's the only way I can make sense out of those two situations. Especially since when it sat for over 4 weeks it was extremely cold weather during most of that. The other time it never dipped far below freezing - when it refused to start after 4 days.

 

These cars sure can be quirky like that....all the wiring and electronics etc

 

I would think that also.. the battery should have at least a 7yr waranty on thm.. Do you think that thats poss.? Should i take it to a regular ford dealership? or where I bought the car?

 

Hi. this battery tender>>> is this a constant charger for the battery? and , can I get it from an autozone, ?

 

I just looked at the thread containing the battery tenders.... I am amazed at how many differant ones there are... Soo,,, which one is the best... ????

If you follow this advice, you will have to idle your
stang for hours just to build back the energy that
the battery draining system has used along with
the cranking amps it took to start the stang.
Nice advice.

A dead battery sulfides faster than a fully charged battery.
Letting it fade away to noting then charging back up is
way no good for the battery and will kill it permenantly
pronto. Tenders trickle charge up to about 14.1 Volts
and then shut off automatically until a voltage of about
12.8 Volts is reached starting the charging process all
over again never letting battery reach a fully discharged
plate damaging voltage of lets say 9V or so.
I forgo the need for a new charger and used my
regular battery charger with a 24 hour timer.
The battery gets a charge once a day for about 15
minutes and then waits until the next day to charge
for another 15 minutes. Plenty of charge for a battery
that only has a slight amperage draw on it during storage.
