Originally posted by Bruce Clark Curious. I don't fly often but the last time I did the airline concerned would not allow any batteries of any type in the Check-In luggage. Laptops cameras flashes etc all had to go in the cabin. Perhaps they do things differently down under.
That's very interesting.
I had an experience once on a flight from Mexico to the USA where an "excess" number of batteries was determined to be in my carry-on. It was no more than the batteries in my Penxtaxes, plus spares for each camera (one set of spares was 4 AAs, one set of spares was 2 OEM batteries). I had the choice of throwing away my 4 Eneloop and 2 OEM batteries or not boarding the plane. They told me I should have placed the batteries in my checked luggage, enclosed in plastic carrying cases.
I calmly complained and a manager came to security with a book full of directives from the TSA & CBP. One page -- with the Department of Homeland Security seal and TSA heading -- was on batteries and carry-on items. "Excess batteries" were clearly prohibited, but the definition of "excess" was not included.
I explained that the TSA had allowed me to fly to Mexico with exactly the same arrangement, but they were not about to allow me to travel
back with "all those batteries" within my access in the cabin. I could not recover my checked luggage at that point and move the batteries. I was stuck.
So... I threw them in the trash, sadly. Since then, I've spread batteries between all my various bags, checked and unchecked, and no one has complained.
I'm here to say that from personal experience, at one point, TSA clearly prohibited "excess batteries" in the cabin. It cost me over $120.
Enforcement may have varied by airport and security training, but Mexico typically includes the xray scan of carry-ons entering the secured area, plus a secondary manual search just before each gate. My batteries were flagged at the xray, before the gloved hands went through everything.
