What do you call normal? What year is your C5, there was an issue that
was changed nearly as soon as it was identified. What is your use
pattern? Do you use them daily of only on rare occasions? Where do you
store them when not in use? How far from the car do you keep the fobs
when not in use? Do you replace the batteries with a quality battery
or a battery of lesser quality? What leads you to think the FOB has an
affect on your car's future dependability or functionality?

My '05 is still on it's first set of batteries from 10/04 used year
round but not daily. I will say that the first thing I did was to cut
out the memory function if that could have anything to do with battery
life.
