I have tried the valet key - no success

Borrowed a battery charger. figured i would give it a fresh charge since it has been sitting for 4 isn weeks maybe more. According to the charger its at 9 amps. I still think that when it was hooked up to my e46 it should have started or at least let me read the codes. But, these are desperate times so i will let the battery charge to 12 amps
