Thebattery in my 05 Mustang V6 convertible has gone dead twice now. This time the dealer found a Tech Service Bulletin, TSB 07-5-13, that describes the condition. Itsays that all the little electrical drains add up and if the 05-08 Mustang is left undriven for about 30 days, mine seems to go dead in three weeks, the batterydrains entirely. And it isn't just on the Mustang. It is also the 2005 Explorer Sport Trac, the 2007-2008 Explorer Sport Trac (wonder what they did different in 2006), the 2005-2008 Expedition, the 2005-2008 Lincoln Navigator and the 2005-2008 Mercury Mountaineer. The solution they tell the dealer is to havethe customer buy a battery maintainer or charger. I don't think that is much of an answer. We should all write Ford and tell them what we think of their solution and which GM product we are going to buy next.

My battery just went dead last Sat. 06 with 18,000. Didn't think anything about it. Went to Kragen and got on for $65. I had no problems before, and Sat morning, battery was dead. Didn't think about having it under warranty.

I also had the 'dead battery' issue twice after leaving the car for a week. I used to let the CD shut of automatically, but since reading about the Shaker-Drainerissue I always turn of the CD off before stopping the engine, and certainly before opening the door. No problems for the last 6 months.

I agree that flatening the battery to zero will permanenttly weaken it, so I must be lucky that two events last year have not had a significant long term effect. I regularly leave the car a week, as I ride a motorcyle a lot and have had no problems.

Left my stang without starting for 7 days, came back and it fired right up. I ensure I turn off the radio at least 20-30 min prior shutting down the engine. I've done this at least 4 different occasions where I would be leaving the stang for up to a few weeks. It works for me...
