People have been predicting the end of the world and society for years and even generations. It has and is happening in some places and I personally really feel the pain and sadness each of those children and parents carry with them every time they dodge bullets as they take their loved one to the grave yard.
Lithium cells must be charged very differently than NiCD or NiMH cells. Firstly they require a special charger specifically designed to charge lithium cells, NEVER use NiCD or NIMH only chargers on LiPo batteries! You must use a Lithium Ion or Lithium Polymer charger that is designed to handle the number of cells you are trying to charge. Charging Lithium cells is the most hazardous part of using lithium batteries. EXTREME care must be taken when charging them to avoid damaging the cells or worse causing them to catch fire. It is important to set your charger to the correct voltage or cell count. There have been fires directly caused by lithium batteries so PLEASE BE RESPONSIBLE when charging lithium batteries.
An acid based battery should be stored at full charge. Nickel and Lithium based power cobalt mining canada cells should be stored at half charge or charge. This will help keep them from using capacity over time, and you will see a better performance from them when you do use them.
Then again, any American who sees a business going into China might consider that business to be a pioneer of sorts. That's particularly since so many people think that China is still in the third world.
A lithium drill is much lighter than a comparable drill of the same voltage. This allows you to use higher voltage tools with lighter weight. Remember, voltage equals power, mah equals the gas tank of the battery. So, if you are using a 12 volt now, a 18 volt or even a 36 volt lithium mines ontario drill will offer you much more power and still have the same run time of you 12 volt with close to the same weight.
There is also a lot of misinformation about batteries in general based on the older models and technology. You do not need to totally drain the new lithium models. Its fine to use it until you get a warning of low power but don't purposely try to push it to empty since there is no reason to do so now. And if you do push it to absolute no power you might also experience some lose of data, a very good reason not to go that route.
You cannot go wrong with this type of plan. In the end, if the world is OK, you still have your gold and silver, you just may have missed out on the next dot com bubble.
