I also have leakage from DURACELL batteries, One is in an UN-opened rezor GILETTE, VERY EXPENSIVE, and in my Mini-Max flashlight. BOTH LEAKED BADLY, Also in my Freon detector, which ruined the battery contacts, These batteries are VERY OVER-PRICED for what they are.
The dates on the batteries in question, are still in the future, I guess they figure as to how many they sell, that they do NOT care if some of them,
or ALL of them LEAK.!
