Lithium batteries may be dangerous and can cause fire if not carried properly. Whether a lithium battery can be carried by air or not depends on its configuration and its Watt-hour (Wh) rating (for rechargeable lithium-ion/polymer batteries) or Lithium Content (LC) (for non-rechargeable lithium metal batteries).

Please use the following table to determine if the battery you intend to bring is acceptable:

I'm trying to figure out my batteries that I will take away with me. And want to understand as much as I can in case I get pinged.

A camera battery I just looked at says 3.7v, 1100mAh. Do you just multiply the two to get watt hours?

Yes you do... so the watt/hr capacity of that battery is 4.07 W/H.

That's exactly what my calculator said too!

Thank you.

It is Watt times hour, not Watt divided by hour, dammit.
