Starting the new year off with a bang, the Wall Street Journal reported this morning that the Transportation Safety Administration has implemented new policies regarding what battery types can be brought on airplanes.
Well, it turns out you can have one in your device, so your camera, laptop, cell phone, and other such equipment is safe. You can also carry two spares, provided each is stored in its own sealed plastic bag or the original packaging. Loose batteries, whether in carry-on or checked baggage, are no longer permitted.
For those that are curious, I have been able to determine that Lithium content is based on a factor of 0.3 per cell multiplied by the rated capacity in ampere hours. If you look at the back of your batteries, it will tell you certain key information that can be used to determine your total Lithium content. For example, on my Canon XT, the back panel shows that it has a rating of 7.4 volts, with 720 Milliamp Hours. It’s the mAh that we need to use for determining how much Lithium we have. So, if I take the rating of 720 mAh and convert that to regular Ampere Hours (remember your metric system?) I get a value of 0.72 (720/1000). Now, I would use that 0.72 and multiply it by 0.3 to get my total lithium content.
|mAh value||Ah value||Total Lithium content|
|Rebel XT (350d)||NB-2LH||720||0.72||0.216 grams|
|Rebel XTi||NB-2LH||720||0.72||0.216 grams|
|1D Mark II||NP-E3||1650||1.65||0.495 grams|
|1D Mark III||LP-E4||2300||2.3||0.69 grams|
|1Ds Mark III||LP-E4||2300||2.3||0.69 grams|
What it basically comes down to, is that you now must put your spare batteries in a plastic baggie, and can only tote those in your carry-on. (You cannot transport them in checked luggage.)
Cell phone: 0.78 grams (0.26×3)
Laptop: 54 grams (18×3)

When I get home this afternoon, I will set this up as a dedicated page so it won’t be archived and add it to the “blogroll” links on the side panel for easy reference. Happy Wednesday all, and go buy some baggies!
