Lithium-ion battery in the airplane

I seeking information on this topic. If I understand it correctly so are batteries 100 Wh not regulated. Further 2 batteries between 100 and 160 Wh are permitted in hand luggage. Over 160 Wh batteries are not allowed. Is that right. What are you doing before air travel with batteries.

Thanks Thomas

I read my airline’s rules on restricted items and did exactly what they said. Zero problems taking them on the flight. might be a good source for information.

The IATA rules say the following:
less than 100 Wh no operator=airline approval required.
battery in equipment OK in carry on and in checked luggage.
spares in carry on as many as you want.
100-160 Wh require operator approval
in equipment OK in carry on and in checked luggage.
max 2 spares in carry on only.
more than 160 Wh:
must be presented and carried as cargo in accordance with the IATA Dangerous Goods Regulations.
In general our batteries are rated less than 100 Wh and fall under the first category.

Printing the IATA doc just saved me losing my LiFe battery at Menorca Airport.

They were all for confiscating it until I talked them through the document.

Do make sure all terminals are taped up tight too. They were keen on that as well.
