In the world of lithium rechargeable batteries, guides and descriptions below will come in handy and expand knowledge base and horizons for those wandering around and trying to navigate themselves through the vast number of abbreviations (e.g. li-ion, 18650, 26650, 14500 ...), and terms not familiar with — related to these unique and powerful Li-ion must haves, used in many high drain-low capacity, and low drain-high capacity applications.
Li-ion rechargeable batteries are a special breed packed with amazingly powerful energy that provides dramatically increased longevity, low self-discharge, efficiency and optimized usage time.
When you think of batteries you might first think of what you've been faced with most in the store aisles. First come to mind widely used AA or AAA size batteries; however, AA or AAA are old technology, and can't match the power of Lithium-ion Batteries.
