    Normal Value for Battery Draw?

    My car keep draining the battery down. At the moment, I only drive it once a week or so and often the battery is too dead to start the car. The old battery had been charged so often, it seems a cell died completely. I just put a new battery in the car (under batter warranty), so before I ruin this battery too, I want to fix the issue.

    Using a Blue Point Amp Hound I borrowed, I'm getting a 0.1 amp draw on Fuse 21 and a 0.5 amp draw on Fuse 28.

    Both are connected to the radio and other things like the cig lighter, OBC, check panel, antenna... etc.

    The radio is aftermarket, but was installed long before ever having this issue. Also, the power antenna is long gone, replaced by a Z3 unit.

    My question is, does a 0.6 amp draw seem quite high? I'm thinking yes.

    Thanks.

    I think it's like 30-50mA or thereabouts. You're over ten times that if your multimeter is set to the correct place value.
