If you don’t use your Duracell AA alkaline batteries for seven years, you can expect them to last that long. Research has shown that when Duracell AA batteries are used normally in things like flashlights and small toys, they can power them for about 100 hours.
Alkaline batteries don’t last as long as lithium batteries. There are also batteries that can be charged. They can last up to 10 years if they are charged normally and used normally. For devices that are used often, like game controllers, it is best to use rechargeable batteries. “No other alkaline battery lasts longer,” says Duracell. Science projects and tests by Consumer Reports seem to back up this claim.
