Need help, car completely dead

[gregy]

I have a 2001 E53 4.4 that I let sit around for about 2 months, the running lights were left on. I didn't get a chance to look at it until this past week, I had the driver's door open so I was able to pop the hood. Typically I can put my portable jumper pack on it to start the car. This time it did not work, I put a 10 amp charger on it overnight, and nothing. Even with a charger attached to the front hood terminals I do not get any power inside, no interior lights or any kind of power. Does anyone know what may be wrong, is there a main fuse that may have blown? Thank you in advance.

Update, looks like some of my chargers were just not powerful enough send power to the car in "supply mode". I dug up my old Noco charger and it was able to give power to the car, the battery is in bad shape but at least I can get to it to replace it now.
