Default Re: Air Con mystery

I assume the C250- has a small auxillary battery like most recent M-B's which is specifically to give a stable voltage to various electronic systems.
They seem to fail every two to three years but the car keeps running without them.
Does your C250 have such a battery and is it in good nick?
