I have recently come across two devices that contained leaking Duracell. The first time I was surprised, but didn't think too much about it. Then it happened again today. My flashlight that I keep or emergencies did not work when I checked it, so opened it. Two AA batteries were swollen and leaked to where I couldn't get them out of the flashlight with out digging them out. I was able to determine they were supposed to be good until 2020. I will not be paying for Duracell batteries from now on.
