Why use Lithium batteries?
Lithium is a very active material that provides a great deal of power relative to the amount of material used in the battery. Lithium batteries are extremely light in weight while maintaining a higher voltage and longer service life compared to other primary chemistries such as alkaline. Non-rechargeable lithium batteries are typically 3.0V to 3.6V in range, but 1.5V AA and AAA formats are also available.
