Is Alkaline better than lithium?
Depends on the usage. In low power drain devices operated mostly at room temperature, alkaline batteries are probably better. In high power drain devices sometimes operated at high or low temperatures, lithium is definitely better. It is best to use what the manufacturer of the device the battery will be used in recommends.

Lithium Batteries Have No Memory Effect?
When you buy lithium polymer batteries, you can do so with the knowledge that they do not have the dreaded memory effect.
