GCOGHILL Perfect battery status replacement for the menubar, this is how it should be. And works great with my APC UPS/battery backup as well.
About the only thing I could suggest for this app would be to have the option to use Growl for updates - switching to battery/charger, fully charged, low battery warnings. And when the battery hits low enough to go to sleep mode, the warning window could be an HUD-style window (or Growl - I can't recall if there needs to be user input). Currently I use a widget for these notifications.
But as-is, still excellent.
