There are no any special drivers for batteries.
I ever see another driver except standard windows on any laptop and table I use.
In my case ext battery is recognised by windows and charged correctly but if I unplug internal battery WebDT even cant start up with single external battery.
It does not even try to do this as if battery absolutelly dead.
But it not!
In the post before I make full tests and have a strange results.
The one of conclusions from these test is: there is no way to check ext battery condition trying to power with it single.
It seems tablet used some sort of technics used in handheld devices with two batteries - it used one to charge another. So, device will work fine and long only with both batteries.
