Alright guys.. so was in the process of sanding/priming and hadn't started up my mustang in about a week. So today I decided to start her up and I got NOTHING. No clicks or any other sounds. So I was like ok dead battery..

I get jumper cables and try jump starting from my other
stang. Still nothing. So I try a 60amp/200amp jump start charger and I got the light inside to turn on when I open the door. SO I thought it was working..

Couple hours later I go to start her and once again NOTHING no sounds either. Then the light inside didn't turn on like it would either. My battery doesn't seem like it can hold a charge/wont charge. Its less than 6 months old, but it sat for those 6 months from the past owner. I was gonna try push starting her to get her to my electrical class in college to see whats going wrong. Except it's a long drive and I don't wanna get stranded..

Any ideas on what the problem can be? Thanks I appreciate any help in advance!!
