VX Calais V8. Battery drain

[alanb]

I just bought this Calais and and am not sure if I have a genuine battery drain problem or not. The battery was flat after I left the car idle for two days. My question is how much current should a VX Calais V8 draw when parked. I have measured 265 MA when I disconnect the negative battery terminal and put an ampmeter in series. I have tripple checked for interior lights being on etc. What I have noticed whether it is relevant or not, is if I remove fuse F6 inside the car, a 10 amp internal lights fuse, the current drain drops to 170 MA. I would think this about normal as the car computer would surely need this ammount to stay active. So, Is 265 MA excessive or not? I have put a new battery in the car but would like to know I I can expect the same thing to happen to it. Holden says it seems excessive but I don't want to give it to them to charge me a fortune for nothing.
