I have found a dreadful lack of battery information In the Ecig world. I will post helpful links here for anyone wanting to learn more about the power supplies we rely on so much. Anyone who wants to add useful links please add them as well.
These are from batteryuniversity.com which contains everything you could possibly want to know:
Types of Lithium-ion Batteries
How to Prolong Lithium-based Batteries - Battery University
Frequetly Asked Questions on How to Charge Batteries
