Lithium batteries in checked bags is Forbidden. Please Google "China Southern Airlines lithium batteries" and it even explains the calculation as I stated for mAh to wh standards. Or Google "China Aviation Authority lithium batteries" and read. It states the same as Thai Airways and the FAA. I would do research before accusations of irresponsibility on my part. An apology tentseller?
To Dean1945, Nimh batteries upon research are permitted in check bags but this type of battery can still heat up from over charging and catch catch fire and explode. They also look like lithium batteries so transfering through a Beijing Airport, they confiscated them. I refuse to transit through China at all cost but other airports can confiscate your nimh batteries also. Always carry any type of batteries in your carry on so your checked luggage is not held up and miss your connecting flight.
