Too much money, no real advantage
What We Think
"EXTRA LIFE. EXTRA POWER." proclaims Duracell's marketing, "Delivers extra life or extra power vs CopperTopAA in a wide range of devices". With claims like that we were ready to test a AA with power levels we had never seen before. The good news: they are technically right - It is the longest lasting Alkaline AA we have ever tested. The bad news: it is 3 times the price of the Rayovac Max Energy while only lasting 4% longer. The other bad news: if you are after longest life possible the Energizer Ultimate Lithium will offer you nearly twice the battery life. That said, they do look really cool and the package offers a resealable top like a tray of oreos.
Pros
Better than average alkaline AA battery life (by a hair)
Name-brand
They look cool
Resealable case may help you lose less of them in the back of the junk drawer
Cons
Barely better than a standard alkaline, yet significantly more expensive.
