hi all, I bought my car 6 months ago.  it's a 2011 dci and it had driven beautifully.  today after driving my usual 50 miles I went to pick my kid up from school. when we returned to the car 5 mins later it was dead. the outside lights didn't flash when I bleeped it open.  the inside lights did turn on.  the immobiliser light is on. I got a jump start and the car did "try" a bit harder for a while after to never got on. 
Is my battery dead or is it an electronic problem. I don't know much about the workings and got absolutely shafted by a mechanic last time I used one.
I have taken little video if i could figure out how to upload it
