I can’t tell you how many devices have been ruined by Duracell batteries. They are complete crap. It took a while and the loss of some lovely tools but I finally caught on. I will never buy a Duracell anything. The company was purchased a few years ago and downgraded their manufacturing.
I'm sure there are poorly made batteries but so far I haven't been able to single out a manufacturer. I've had several flashlights ruined by leaking Duracells as well as other name brands of batteries. I've never had a leaking Japanese battery but that might be coincidental.

I have dozens of devices that use "coin" batteries (e.g. CR2016, CR2032) and I never have had a leaker. Is it the chemistry or the case construction that makes these so device-friendly?
