Which is better lithium or alkaline batteries?

Lithium, an exceptionally light metal, gives lithium batteries the highest energy density of any battery cell. Thus, they can store more energy than alkaline batteries or any single-use battery of a comparable size. And they are superb performers in extreme temperatures, both hot and cold.

Can you use a lithium battery instead of an alkaline battery?

Energizer e2 lithium AA batteries produce 1.5 volts, so they can be used to replace any regular alkaline AA units in most cases. Lithium batteries operate in extremely cold climates or extremely hot climates where alkaline batteries cease to function. WEIGHT: Lithium batteries are much lighter than alkaline batteries.

Why are alkaline batteries better?

One of the advantages of alkaline batteries over other primary batteries and rechargeable batteries is that it has higher energy density. For example, this battery has double the energy density of a Leclanché cell and zinc-carbon batteries. It has longer shelf life than batteries with chloride-type electrolyte.

How much longer does a lithium battery last?

The typical estimated life of a Lithium–Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.
