What the heck, I'll do it too, new FAA lithium battery restrictions

It's all over the net by now, but worth looking into if you travel to/from/or within USA by airplane. While general perception is that the NEW rule applies ONLY to the loose or spare lithium batteries, the reality is somewhat different.

DOT official page on the lithium battery restriction is available here.

The key is that ALL batteries MAY be affected, depending on their size. While the rule appears to not be affecting any consumer level batteries that are installed in the relevant device, the larger packs (for portable lighting for example), might be. Check the above out and look up the lithium content in your larger packs to make sure you won't loose any at the check point.
