Car not starting???

[pavanbabut]

Hi all,

I had problem today, when my friends tried to jump start my car after 3 months. I know the battery will be dead, but its not even kicking in when they try to jump start. He is telling that even the dashboard lights are not even showing up. I sugested him to take out the battery and get it recharged fully and meanwhile try to start it with installing a new battery in it.

Do you guys have any idea wht might be other possible causes in these type of situations (car is sitting in the parking lot for 3 months without even starting)
