I purchased 3packs of Duracell AA batteries today at my local Dunelm store. They were on offer at a good bargain and I had been using them all over Christmas to power our fairy-lights. But the last pack I opened today failed to make the lights work & were scalding hot to touch when removed and the labels on the batteries were split and peeling off. I've never seen batteries do that before and I believe they may be fake. The other packs bought today look the same but appear to be ok.
