Something I learned and want to share with everyone.
This is directly from American airlines website
Batteries
9-volt, AA, AAA, C, D, alkaline, carbon zinc, silver oxide, zinc air, lithium, nickel-cadmium, nickel-metal hydride
Guidelines For Lithium Batteries As of January 1, 2008, travelers may no longer pack spare lithium batteries of any kind in checked baggage.
Passengers wishing to carry spare lithium batteries for devices such as laptops, cell phones and cameras are now required to pack them in their carry-on baggage with the terminals covered/insulated. Travelers may check bags that contain batteries, as long as they are installed in electronic devices.
As stated above batteries must be in your carry-on, however when I reached the xray machine leaving Cozumel the Mexican TSA tried to take all my batteries. To say I was unhappy would be a vast understatement, I refused to just let them take my batteries and went back thru security to the American airlines check-in counter. Once I arrived at the counter I ask for a supervisor and showed them
their own list of prohibited items in your carry-on posted on the counter.
Batteries were not on the list and then they proceeded to tell me their list was correct but the Mexican officials have their own rules.
Now as you can imagine I am even more unhappy now and want them to issue a separate baggage box for my batteries or return my luggage so I can put the batteries in it. Which now for some reason is ok even tho their own website say you can't do that. Lucky for me another passenger offered to put my batteries in his luggage.
I urge everyone to check their airlines rules on batteries but understand Mexico seem to make up their own rules. Unfortunately if we want to travel now-day's we have to put up with type of treatment.
Please note I had the same batteries in my cameras and strobes in the same carry-on case and they never said nothing. In my opinion it is case Mexican TSA workers taking stuff to sell later. I am by no means saying all Mexican people act this way but the group at the xray machine that day were taking things that people brought thru American TSA security on the way down.
Again I love the Mexican people and have found in my many trips to Cozumel that they are very honest and hardworking folks. I can only tell you what happened and my feelings towards those at the security xray machine. Most folks would just let them take have the stuff as my wife seen while waiting for me to return back thru security. She told me that while waiting for me to return, they were taking stuff from about every 3rd or 4th passenger. (including a collapsible fishing pole)
I cannot believe that this many travelers (who passed TSA on the way down to Cozumel) forgot what was allowed and what is prohibited.
I would like to tell you what to do but it seems they make up the rules according to who is working that day.
Just a heads up.
PS: I had well over $150.00 in batteries but even if it were only $5.00 its the principle.
