Just to warn you guys that Amazon were fined euro 20,000 for incorrect labelling on watch batteries that were delivered by air.
So playing games with incorrect labelling is not worth the risk.
I was in the queue at Guangzhou airport ,the guy in front had some form of battery booster that exceeded the limit,he had to take it away to some special location and had to pay for its disposal,as well as losing the product. He tried to argue but the airport police were quite firm,any more arguing and being banned from flying would have been the least of his problems!!!!
No excuse there are big signs telling you the limits.
KudosDave
