Power status menu shows mouse battery only in menu bar, confusingly

Upon upgrade to Ubuntu 12.10, the power status menu started showing the battery charge of my Bluetooth mouse (an Eclipse Touchmouse), which is very nice. However, because there is only one battery shown at once in the menu bar, I did not at first realise that it was my mouse battery being shown, and I could not work out why my laptop battery was only at 30% charge and was not showing as connected to AC power. In the end, I showed the power menu and discovered that there were two batteries in it, which helped clear up the confusion.

This would have been much clearer if the battery icon in the menu bar were a picture of a mouse. It is possible that Ubuntu does not know enough metadata about my mouse to know that it *is* a mouse and this is why it appears merely as a second laptop battery. Attached screenshot shows that Ubuntu believes my mouse to be "unknown technology" and its Type to be "laptop battery". However, the device ID contains "_hid_", which suggests that something somewhere in the system is aware that it's a battery for a Human Interface Device (possibly "human input device"), and thus not the main battery for my laptop. The model is also known ("Eclipse Touch Mouse") although of course that's only unparseable text.

There may be two bugs here: that it's not obvious on an Ubuntu upgrade that there are now two batteries shown when one was shown before, and that Ubuntu is not correctly identifying my Bluetooth mouse *as* a mouse. I am happy to provide metadata to help with the latter case.
