Version: 4.0.82 (using Devel) Installed from: Compiled sources The battery applet is not updated when battery is removed and still displays the last known state. Adding a new second battery applet displays the correct state.

I can confirm that. The status is no longer updated even if you put the battery back in. Same for starting KDE with no battery plugged in.
Still present in 4.0.98.
Let me take that last comment back. Debian hasn't packaged the Plasmoids from 4.0.98 yet due to a change in the package name. I'm still running the Plasmoids from 4.0.84. Sorry.
Does this still happen with 4.1?
Yes, the bug is still present in 4.1.
Fixed in r850685 (4.1) and r850683 (trunk/4.2).
