If not in use, Duracell AA alkaline batteries have a seven-year estimated shelf life. According to studies, Duracell AA batteries can operate a gadget for up to 100 hours when used in everyday things like torches and small toys.
Alkaline batteries have a shorter life span than lithium batteries. There are also rechargeable batteries available. They can last up to ten years in typical use with proper recharging. For devices that are used frequently, such as game controllers, rechargeable batteries are advised. “No alkaline battery lasts longer,” according to Duracell. This claim appears to be supported by studies ranging from research projects to Consumer Reports testing.
