The advantage of the Duracell batteries is in their processing to increase almost twice the battery life. With Duracell I actually only had good to very good experience, even if these batteries are not required for a longer period. So also ideal for storage in a shelter. Even with very long storage me not a single battery by Duracell is still leaked, can keep an advantage by only a few manufacturers. This of course comes at a price, which is higher than at 08/15 batteries.
The Twelve Pack of AA batteries is suitable if you already used for stockpiling or amount of battery-powered devices in the household. I am very happy with it definitely.
