High Battery Drain issues

Don't know, don't care. Just passing along what the dealer told me.

Plug it in once in awhile. ..... two batteries, one replaceable one rechargeable.

Which battery powers the data collection?

Oh and dealers are never wrong.

The CR-2032 powers it all.

So now you know the truth and can stop the spread of misinformation.

Nowhere in the paragraph does it say that there is "only" one battery. Do you honestly believe that BMW makes two key housings for an option with probably less than 25% up take? The manual also says plug the key in to the slot at least twice a year. Why? The CA battery isn't rechargeable. ????
