Rated 5 out of 5 by from Can't Live Without; Ultra Dependable. I have used Duracell's for as long as I can remember using batteries. They have never failed to offer ultra-long power. Most importantly, I had them "imported" to Peru by friends when I was a foreign correspondent so I could use the batteries in my professional recorder in order to tape interviews, gather sound and produce my reports. Peru sold them at exorbitant prices because of import taxes so everytime a friend visited from other countries, I had them stuff their luggage. The Duracells almost always cost more than other brands, sometimes substantially so, but they last much longer, and it's that dependability that is so crucial. I've used them in all sizes for items ranging from electronic remotes to battery-powered razors to old-style Walkman music players, and from flashlights to sometimes critical hurricane lanterns. I depended upon the latter items while living in Florida for many years because of the many storms that took out the power. I stocked up on many D's, in particular, for lanterns and lights. In those and other cases, when kept in uncommonly used devices, I've found the alkalines rarely crust over, although it has happened on occasion. I don't think they've ruined a single item in all my decades of professional and personal use. I've had to use and/or tried less-expensive batteries and there's a clear difference in strength, and therefore reliability. In rare cases in life, you find an almost-perfect item upon which to rely. To me, the alkaline Duracells are must-haves, and you can believe me when I say no one ever paid or even approached me to test these.

Rated 5 out of 5 by from Duracell the test of time I have to say I don't purchase batteries often, it may be my generation, and it may be just the evolution of electronics now. I wish I had gaming controllers that still used them to really put these batteries to the test, those things ate batteries left 'n right with the hours I put in to those. However, there are a few things in my home I still purchase batteries for that I need reliability for the long term. My smoke detectors and my wall clock! It's no bueno when those batteries go out. I definitively say these are going to outperform or outlast other battery brands in these devices in the 45 days I've been using them. What I can say is my opinion on these batteries, as a consumer, money no object, I would purchase Duracell solely on my feeling that these are the top tier name brand batteries. In my 28 years of living, their marketing campaigns have ingrained this in my head and have yet to be disappointed. Call me in 10 years and I'll let you know if I've changed my mind :) [This review was collected as part of a promotion.]
