An alkaline 9V battery's shelf life (storage in excellent condition) will normally be around 10 years. A 9V battery's lifespan might vary depending on a number of variables. The battery's chemistry or quality and the load you are applying to it are what matter most. Battery life can go up to 5 years when used in applications that only use a small amount of energy. Battery life may be shortened by more demanding applications and unfavorable environmental factors like heat and dampness.

Everyone should charge the new NiMH battery before using it after purchasing it because it often only has a modest amount of power. It is advised to use the battery first before charging it if the battery has recently left the factory and the power is adequate. New NiMH batteries typically need to be charged and used three to four times before their performance is at its peak.
