    I love this brand and have been using these batteries over 20 years. They last longer than most similar batteries. This is a true premium brand that is high quality and long lasting. Energizer has a well earned reputation as a top notch battery . I use this brand for all of my battery needs and urge you to do the same. Highly Recomended !

    Bought these to replace my smoke detector batteries after they were giving me the signal that it was time to replace them. I always write the date on the batteries when I put them in. Old ones lasted five years (they were Energizers too). Looking forward to five more good years! Pros: fit well, nice rectangular shape, shiny, last a long time Cons: Pricier than Rayovac, they aren't used for important jobs like Duracell
