First off, Apple has known of this problem for years so it appears that they are not interested in addressing it...
Second, and this is to Netherzone, Apple is not interested in maintaining the planet. If they were, we would have access panels on the millions of iMacs, iPods, iwhatevers, so that we could replace components that are known to fail or on an exponential enhancement path, i.e., batteries, optical drives, hard drives, solid state drives, etc...!!!
Instead, we are faced with ridiculously unrealistic repair and part prices or discarding a perfectly upgradeable machine into the landfills.
That being said, I love Apple products over just about anything else.
UPDATE AND FIX...
****reposting****
Open bluetooth preferences and delete the keyboard completely. Turn off the keyboard and restart the computer. I zapped the PRAM (hold down the Option, Command, "P", and "R" keys while booting until the computer chimes four times). Once booted, turn the keyboard on and reregister it with the computer.
A new set of batteries was installed on Dec. 1st and the keyboard is still showing 93%.
Hope this helps anyone experiencing a similar problem.
Note: This problem has reappeared on occasion, but after performing the above routine, all returns to normal.
