Duracell Coppertop AAA Alkaline Batteries 4 ea

Dependable brand, great prices

When I received this 4-pack of AA batteries, I decided to do a little test, because I could think of no way to actually rate batteries, other than, yeah, they work! The opportunity presented itself when my sister visited for a family vacation. She was using rechargable batteries from a different company in her baby monitor. Typically, the charge on those batteries lasts for 12 hours of usage before needing a recharge (the monitor takes 3 AA batteries). I asked her to use these Duracell batteries instead, and we timed the usage to see if these Duracells would last as long. Needless to say, they far outperformed the rechargables. She used the monitor a bit more heavily than usual (the kids were in a "weird" bed and a were more restless than typical), and they were going strong far beyond 12 hours of usage. When she left she gave them back to me and I have now used one in my electric razor for several more days. It is still going strong! 5 stars. I have absolutely no complaints. I received this product for free from Duracell in exchange for my honest opinions- as always, all opinions (good and bad) are my own. [This review was collected as part of a promotion.]
