Shelf Life. While an alkaline battery is reliable, it has a shelf life of about 7 to 10 years. Around that time, the chemicals within the battery become stagnant and no longer produce a chemical reaction to power the battery. Some people believe that placing unused batteries in a freezer extends their shelf life.
Putting batteries in the freezer or refrigerator doesn't necessarily prolong their life. Alkaline batteries stored at room temperature self discharge at a rate of less than two percent per year. So normally refrigerating or freezing them will only help maintain their charge by a tiny amount.
