     I think you have misinterpreted how the card battery is used. It is
not only used when you pull it out of the 48. It is used when the 48 is
turned OFF. The card runs off of 48 batteries only when it is turned on.
Thus, if you are a regular user like most, the card is supported most of the
time by its internal battery.
