Uninformative display with multiple batteries

[Roger Binns]

My laptop has two batteries (Lenovo Thinkpad) with the main one and a second one instead of the DVD drive. This indicator correctly knows that there are two batteries - clicking on it to get the menu shows both batteries and their (separate) statuses.

However the icon/text display only shows the first battery. This system drains the second battery completely first. The text display will just say "100%" until the second is drained at which point it starts counting down. Similarly it only shows charge remaining time for the first battery. (The drop down does show correct information.)

The calculations should be summed over all batteries in the system. For example the time remaining depends on the sum of all battery remaining charges divided by the sum of all battery discharge rates and something similar being applicable for charge time.

For me the situation is even worse: Since 12.10 the power indicator displays my laptop battery and my MOUSE battery (Belkin bluetooth mouse) as second battery. Unfortunately it always chooses the mouse battery for display in the panel.

This is of course completely useless, as I want to see how long the laptop battery lasts, not how long the mouse battery lasts. It seems to be impossible to select which battery to display in the panel?

I don't know if my problem should be defined as "new" bug as it seems closely related to the old one here?
