The Batt on my durango just dies for no reason... Its less than a month old and it used to do it with the old one... If i let the truck sit for like a day or two with out starting it it wont start when i get back to it.... Is there any thing that im missing? Any suggestions would be awesome!

 

Maybe a light is draining it (think ashtray, glovebox, or the light under the hood not going off for whatever reason). You also said you have an aftermarket stereo in that thing right? Maybe you need a stronger alternator to compensate for the drain and upgrade to a yellow top...

 

About 2 mos ago, I left my vehicle all day and came out to find the batt dead. AutoZone said good batt, recharged, OK for about two weeks. Left the vehicle set all day and came out to find the batt dead. On Sat, I pulled the vehicle into the garage and was going to look for drains. I just happened to put the park brake on. Before getting out, I noticed the Brake light was really dim. The key was in my hand. Then I noticed the gauges were starting up, moving up the scale slightly and dropping off. Obviously a drain was taking place. I started popping fuses and when I got to the a/c-heater blower, it stopped, brake light went out. What it boils down to is that on those two days, it was slightly cold when I got in the vehicle and I turned the a/c-heater switch to the off condition. With the switch in the off condition, the batt is being drained(somehow,) with it in the on position, I am not having any problems. I have had some other problems with the door locks/fob not working right. With the switch in the on position, I have not had any of these problems continue.

Now try explaining that to your local mechanic.
