Probably the single most common misconception about E9x BMWs.
Comfort access key fob doesn't have a rechargeable battery; non-comroft access fob does.

Odd....I thought I read in the manual to place the key in the dash on long trips to charge it.

That's part of the problem. The manual does say this, but elsewhere clarifies that this is only for non-CA cars.
