I'll add to the choir, but re: Duracells in general. I'm not a Costco member, so I tend to purchase my alkaline batteries from hardware stores, etc., and I had a dismally bad run with Duracells a few years ago. I switched to Energizer, and I've only had maybe one leakage since. (And that incident could've been attributed as my fault, since I left the batteries packed for several years.)
