Cat eyes and batteries

Or, cat eyes re-visited.  I had this problem before, just sitting in the shop.  The transmission shift pad starts beeping and showing the cat eyes.  It has been sitting for a couple of weeks.  Shows no codes.  Since one of the suggested causes was low voltage I hooked up a battery charger to the coach batteries, even though they tested over 12 volts.  That solved the problem.  Took the charger off for a day and the problem returned.  Charger on again, problem disappears.  Batteries are new but I'm suspecting a problem with them, but the other question becomes, why is the transmission caring what the voltage is when it's shut off?  I'm guessing there must be a constant drain on the batteries to maintain a computer or something in the transmission?

Gayland,
Check and clean all the grounds related to the coach and starting batteries.

I've been off on a trip.  I had the batteries checked while I was gone.  One of them was bad, 5 month old from Napa.  They gave me a new one, haven't had any more problems so far, at least not with the coach batteries.
