80mA isn't that bad. That can be a combination of things like the radio,alarm,immob,telephone,clock,etc all drawing a little current adding up to 80mA. Don't worry about it unless you experience trouble. If the battery drains in less than a week something is wrong or the battery is defective. To give you an idea : a standard LED draws about 10mA and can run about 6500hrs(270 days) when connected to the average car battrery(657).
