Had the H2 to the dealer, they can't find the problem Battery keeps going dead. Sometimes it goes in one night, sometimes it may take a week. I usually keep a charger on it. Drove it last night and today it was completely dead.

Sounds like you have a problem with the computer controlled of the field generation circuit of the alternator-If its a short that's eating the battery I don't think you'll last a week than starts again
