I still remember well the drumming bunnies from advertising. One by one they stopped drumming because it was "the juice assumed". In the end only a drumming: The one with the Duracell battery! I can not really say whether Duracell batteries last longer than those of other reputable manufacturers, but I've done both personally and professionally good experience with Duracell AA batteries (AA / LR 6). You keep really long. Therefore, from my side the full recommendation for these batteries!
