Dealers and Sellers please take note and please reconsider how you ship Li-ion Batteries. Your methods need to be Consistent and Safe. The biggest reason why there is so much of an issue with shipping Li-ion batteries is due to poor packaging. Too many times, you treat batteries just like any other item and that is incorrect.
This goes for ALL batteries, but especially Li-ion. The batteries should NEVER be able to touch each other at the poles, (ends). The best method of shipping would be to wrap each battery separate, in bubble wrap, or to place them in a container so that they cannot move at all. Here are a couple of photos.
Here are some ideas for packaging. Just suggestions, but you will get the idea.

I am just using plain bubble wrap. 12x12 sheets and I cut the sheet to 6x12. I have simple poly bags and I used colored tape, just so you can see the tape.

Take one bagged battery and fold the bubble wrap over it and tape it down.


Place the next bagged battery against the first one and then roll the first one over this one, so both are covered and tape it down.


Fold the other end up and tape it.


Just add more tape to seal the ends.

Here's another way.

Put the batteries in individual bags, onto the bubble wrap and tape all of them together and to the wrap.


Fold the ends of the wrap over and tape.


Fold the other ends over and tape it all together.

It makes a good, strong package.
Or, just use the hard plastic battery holder that all of you carry and make sure to tape them closed and bubble wrap them.

All I am asking is to be safe when shipping batteries to us and take responsibility for your packaging methods. Yes, it might be a few cents more, but I know without a doubt, that packaging like this will only cost you a cent or two, per package.
Just do it.
Thanks
