Regarding the other half of this ticket: showing the mouse battery instead of the notebook battery /might/ be correct, but it depends on the state of the two batteries. The spec at https://wiki.ubuntu.com/Power#Title states the decision should be based on "what you need to know most: what device will lose power soonest (and optionally when), or otherwise which device will take longest to charge".
I've filed bug #1071645 to cover the other half of this bug separately.
