Hi, I own a 2008 Dodge Durango 5.7l Hemi 4x4, and it won’t start. The battery is about 6 months old and was found dead due to the 4x4 constantly activating and deactivating when vehicle is off. Was able to jump it and moved it to an another place where it sat for a few days. Tried jumping it the other day and it wouldn’t do anything. So I took it to advance auto to get it tested and charged. They said it was good and charged it over night. Put the battery back in and now it’s doing what is shown in the video (I tried jumping it) link with this post. The alternator is newly replaced as well. I’m truly at a lost here, if anyone could enlighten me on what to do that would be helpful. Thank you for your time

 

I would try another battery. I went thru the same thing on my Mitsubishi pickup. I ask the auto store if they have a VAC40 battery tester, and they say no. They charge the battery and I put it back in. Short story, I took the battery back and brought a new one. And it has worked fine since. They didn't want to believe until I showed them my ASE patches. So I would try a new battery.
