Current drain - what is normal?

[jamesh764]

I've just replaced the battery (for the second time in a month) on a friend's Cerbera as it was so flat the car could not be jump started.

The alternator is charging enthusiastically (maybe a bit too enthusiastically - it measures 14.9 volts).

I've measured the current consumed by the car with everything switched off, and it is 0.2 amps. Therefore the 60 amp hour battery will be flat in a fortnight.

I know of a woman who used to leave her car (not a TVR) undriven for months at a time while she had intimiate relationships with men around the world, and the car would always start when she got home.

So my question is, does this Cerbera have something wrong with it, or do they all use that much power when they're not being used?

Thank you for all the replies so far.

We had an Alfa with the M99T alarm, and that was fine to leave for weeks without flattening the battery, so that would imply Meta is correct when they say the alarm has a "low current drain" (assuming it's not faulty of course).

I think I need to spend a morning pulling fuses to find out which circuit is doing the draining.
