Chemicals in the batteries will react with air.
AAA is the size of the battery, there are many types and makes of AAA battery and the shelf life for each is different.
if you mean shelf life they last for years if stored properly
The shelf life for this battery is between 8-10 years if it is unused. Most batteries have a shelf life of 5-10 years unused. So the choice is yours my friend.
Because the chemicals that are in it only stay good for a limited time. A reaction is ocurring in a battery from the time it is filled with the electrolyte. That can only happen for so long with or without a load.
The shelf-life of a dry cell is the time needed to remain 80% of its capacity without using it.
I would not buy one that is over 6 months old. But the shelf life is at least a year. After the battery sits on the shelf for over 3 months it is a good idea to charge it before putting it into service.
AA battery have a 7 year shelf life on average.
3 cell battery life is approximately 3 hours; 6 cell is 6.5 hours
Most 9-volt batteries have an estimated shelf life of up to ten years. At the minimum, they will have a shelf life of four years. Most packages of 9-volt batteries will claim a shelf life of somewhere between seven and ten years.
Yes - they have a limited shelf-life' as they will eventually go mouldy.
The Compaq Presario R3000 battery has an original cell type, Li-ion chemistry, and a capacity of 4400mAH/ 8- cell. The battery has a life of 11 hours.
It depends on how new the battery is (in other words, how long it has been sitting on the shelf), but in most cases it will.
