b) each battery must not exceed the following:
– for lithium metal batteries ,a lithium content of 2 grams; or

– for lithium ion batteries, a Watt-hour rating of 100Wh;

c) each battery may exceed 100 Wh but not exceed 160 Wh Watt-hour rating for lithium ion with the approval of the operator;

d) each battery may exceed 2 grams but not exceed 8 grams lithium content for lithium metal for portable medical electronic devices with the approval of the operator ;

e) batteries contained in portable electronic devices should be carried as carry-on baggage; however, if carried as checked baggage:

– measures must be taken to prevent unintentional activation and to protect the devices from damage; and

– the devices must be completely switched off (not in sleep or hibernation mode);

g) spare batteries, including power banks:

– must be carried as carry-on baggage; and

– must be individually protected so as to prevent short circuits (by placement in original retail packaging or by otherwise insulating terminals, e.g. by taping over exposed terminals or placing each battery in a separate plastic bag or protective pouch);

h) baggage equipped with a lithium battery(ies) exceeding:

– for lithium metal batteries, a lithium content of 0.3 grams;
or

– for lithium ion batteries, a Watt-hour rating of 2.7Wh must be carried as carry-on baggage unless the battery(ies) is removed from the baggage, in which case the battery(ies) must be carried in accordance with g);

i) no more than two spare batteries meeting the requirements of c) or d) may be carried per person
