Yes, when the working battery has 5% the system change to the other one and the built-in battery status changes too.
By the way... i set:
pmset -a diskleep 0
pmset -a sleep 0
pmset -a displaysleep 0
From terminal to never sleep because the power management in system preferences doesn't work.

The dual battery works fine, with HWMonitor i see the levels of the 2 batteries.
@RM,
Thanks for the heads up ...
Hoping you two can compare notes and come to some conclusions...
@RM & @Tlacuas,
I started to look at writing DSDT code that would return the values for the currently charging/discharging battery and then switch to returning the values for the other battery when a switch over occurs, however the code all got a bit messy,
