[This review was collected as part of a promotion.] I got these for my daughter who recently got a new camera with a flash. The flash takes 2 AA batteries. When you are taking pictures you want a reliable powerful battery so you can capture that picture. You may only get one chance so you want it to be right. We also use these batteries in our remotes and hand blenders. I do not want to be constantly changing them, I always prefer to go with the best and Duracell is the best and this is their best AA battery. so this is the one you want. I highly recommend Duracell Optimum 1.5V Alkaline AA Batteries, Convenient, Resealable Package, 4 count. It also come in a resealable package to keep them fresh until needed.
