Apple Bluetooth keyboard battery level meter is false

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Just start btbatstat

What is the expected output? What do you see instead?
It should display the same battery level info that system preferneces gives, 
but only the mouse battery level is correct the keyboard battery level is 
always less than the real value

What version of the product are you using? On what operating system?
10.7 Lion, imac and macbook

Please provide any additional information below.

Can you please provide me some screenshots and the output of the following 
shell commands:

ioreg -rc AppleBluetoothHIDKeyboard

ioreg -n IOAppleBluetoothHIDDriver |grep -i perc

All at around the same time so I can compare the output with your screenshots.

I was looking for some documentation to confirm that the 'Apple Key' like icon 
was the keyboard and the other icon was the mouse and found this bug report.

I possibly have the same issue - screenshots attached.

The second shell command didn't produce anything... "ioreg -n 
IOAppleBluetoothHIDDriver |grep -i perc"

System: iMac, 2.5GHz Core i5, OS X 10.7.3

You should make as Migthy Mouse developer. It detects right if I use batteries 
in my mouse, and if I use NiMH accumullators it detects wrong charge.

Does osx report it correctly with the NiHM battery?

ioreg reports: 
  |   "BatteryPercent" = 63

I'm not sure who is right here :)
