So, it is suggested that a quality AA battery can hold its storage for 2 to 5 years.
Recharging Time
By seeing the recharging time of a AA battery, you can easily come to conclude the average shelf life. How many times you can charge a battery, that defines its lifetime. So, the more recharging time a battery has, the longer its shelf life is.
Voltage
The general voltage for AA batteries is 1.2v to a max of 1.5v. However, some 14500 come with a voltage range from 3.6v to 3.7v. Usually, the voltage wouldn’t be a fact if you use the battery for our regular use devices such as RC devices, gaming controllers, remotes, toys, flashlights, and so on.
