I'm]I haven't heard that but I can believe it. In my experience Duracell is the worst offender for leaking. I finally gave up and quit buying them.
John's correct, I spent 35 years in consumer electronics and saw many leaky Duracells. They advertised " copper top" but the only copper is the color on the label. Eveready seldom leaked. At one-time they would replace your item if it was damaged by one of their batteries.
There's household cleaner called Lime Away that makes battery corrosion disappear. Apply it with a cotton swab, leaves the surface like new, almost.
