BTW, the article gives the secret for shipping Li-ion batteries:Do not charge them! Only those with a near-full charge have the power to explode and cause firesl Besides, when they are installed in a device, there is little likelihood of them getting against something and shorting (and causing a fire).
Shipping them fully-charged -- in bulk -- is invitation to disaster!

Apple rcently shipped to me (@ no charge) a replacement for the three-year old battery in my MacBook Pro. The instructions included, "Charge fully before using..."
The law is pretty clear ~ you cause it you own it. So if you ship a fully charged battery of any kind without totally following the hazmat rules and it does something that injures an employee in the supply chain ~ whether that's UPS, FedEx, USPS or somebody else you can be liable for just all sorts of things.
The lithium batteries are just one more in a series of troublesome devices.
I'm not sure I'd trust a fully charged lithium battery coming in the mail at my house if it originated in China. No way to know who packed it for one thing.
I don't bring their fireworks indoors either!
