It looks like you'll have to start removing your cell phone battery and placing electrical tape over the contacts just to get on the plane. That's what TSA is looking at.
ptulmer makes a lot of sense. What TSA is looking at however is scary. US Government agent with weapons carry credentials is allowed on airplane with his pistol - but only after he surrenders his nail clipper.
When you consider the number of Lithium batteries carried on airplanes over the past years, the chances of an incident are much lower than both the pilot and co-pilot having a heart attact at the same time. But they have a better union. :-)
What is next? Removing the lithium battery from your Casio watch? It will only take one bureaucrat wanting to make a name for himself to make it happen.
Know your battery, and how it operates. Knowledge is better than cast iron pots in keeping you safe.
