Ordered in February me 2 packs of batteries; after the first two batteries have kept just 4 weeks in a mouse (the Aldi batteries keep else a year!) I was wary. Then have at all times the battery voltage measured (no load), and found 4 more batteries that had not even 1.2V, with two already crystals had formed (flow phenomenon). The Batterein are reported with a shelf life until 2019; usually I could always rely on Duracell Batterein example of Saturn; This suggests the suspicion of counterfeiting! I see that already complain but some people; Amazon needs to pursue the times!
