I have bought duracell coppertop batteries for over 35 years. They are no longer reliable. Batteries that supposedly don't expire til 2023 leaked. Not happy with ruined electronics. Doesn't seem to be anywhere to find a place to claim guarantee or file a proper complaint. What a joke!
I would give 0 if that was an option. I have bought Duracell for years. Not anymore. This past couple of months - first a AAA battery leaked in remote control (expiry date 2022) and then a AA leaked in the computer mouse (expiry date 2023) Another set of AA's totally ruined a vintage Furby.
I owned Duracell batteries for many years since i was a kid and they work very good. but sometimes I face unexpected leakage that has damaged 2 flashlights so far hopefully that wont happen again. other then that have been pretty good batteries to use. Just keep a eye out for leaking batteries.
I am a photographer I have use Dura Cell Batteries for years, no problem. NOW in the last 12 months the dura cell batteries have leaked into almost every flash, every controller. Something has changed in the quality. I have used my last Duracell ...
