Better Battery life indicator?

[Marvout]

I've just moved from a X61 Tablet to an X220 with a slice.  So far I'm liking it.  But, is there some way to get a better battery indicator?  I can't get Windows7 to show me that there's a second battery installed, so their indicator is useless once the slice is attached, only showing me the state of the internal battery.  It doesn't start changing until the slice is at 0%.

The Lenovo battery indicator is very big, not very good looking, pessimistic in the estimation that it shows and fluctuates way too often.  Needless to say, I've hidden it.

1. Is there any software that could tell a clearer truth of where my batteries are at?

2. Is there any software that shows a graph of battery(s) charge level over time?  (I've got Rainmaker running on my desktop and use it to show me that state of my machine.  I have graphs like this for upload/download, CPU, CPU temp, but I haven't found one for battery charge.)

my X220 shows the combined battery life of both the internal and the slice battery.
