Thanks for the link, but it just confused me more.
1) My cell phone has a lithium battery in it, as do most. How is this OK to bring on a plane. And would that mean 1 could buy a taser on the mainland and bring just the battery in their pocket or carry on?
2) What if I use a CR123 lithium in my WML and trasporting a firearm in my checked baggage on a plane. Or putting a laptop/cellphone in my checked baggage.
3) if shipping an item with a lithium batt in it, do you just slap the right sticker on it and g2g? Or do you pay extra in some kind of hazmat fee
4) I went to the UPS site and you can select an option when shipping batteries. But a small box cost $75 to ship, IDK if this is due to the hazmat mentioned in #3.
5) Sounds like there is an issue with lithium batts, are any companies or tech starting to shy away and use something else? Or invent something better that doesn't catch on fire as much?
Looks like a can of worms was opened with this sub topic.
There are lithium batteries in phones, laptops, tablets, smart watches, headphones/earbuds, and any number of devices we travel with. Those are not deemed as much of a fire risk as when they are shipped unaccompanied.
When TRANSPORTING a battery, you have direct contact with the battery or device containing it. Not the same as shipping it inside a box located among a bunch of other boxes. The rules are stricter for shipping vs. transporting.
There have been exceptions, like when some models of phones caused a slew of reports that they were overheating and catching fire. Those models were banned from flights for a short time until more could be determined as to the cause.
If you read that PDF, the restrictions are based on a combination of factors: the type of lithium used, the size, the watt-hours it can hold, the degree/level of charge in the battery when shipped (30% or less is allowed for things like laptop batteries), whether it's installed in a device or packaged in a way that prevents its contacts from touching anything else, etc, etc.
The manufacturers usually comply with all these restrictions and hoops they need to jump through, so they can send you that phone or laptop through an air carrier. Individuals and to some extent retailers, however, are not as trusted. My daughter tried to ship a smart watch to the manufacturer for warranty replacement. Even after following the list of steps to properly box it up and place the sticker they sent her on the outside announcing lithium battery inside, and calling UPS to pick it up while notifying them of the contents, the day after they picked it up it was returned because .... it contained a lithium battery!!
As you noticed, the rules are confusing, which means the shippers and collection points for the shippers are going to be hit or miss regarding what they will accept. They either know the rules inside-out, or they go the easy route and reject most battery shipments.
I noticed Amazon is very inconsistent. I've ordered blister packs of batteries there, but I have to try multiple listings before I get one that Amazon will ship to Hawaii. I know I've also had at least 4 cell phones and 3 MacBook laptops mailed directly to my house. I've also mailed a couple of cell phones for warranty replacement or upgrade trade-in credit, too.
The fact that UPS returned a package they full well knew had a tiny battery tells you how messed up the rules -- or at least the understanding of the rules -- are.
