I've never met an alkaline battery that didn't leak on something important. Duracell is by far the worst, but now Energizer has jumped to the lead. I'm on the bandwagon with everyone else, Lithium primaries for the stuff that sits long term and not used much and Eneloops for the rest. Neither battery chemistry has ever leaked on me.

Make a note right now of a stored radio, flashlight, or important electronic device that you have not used this year. If it has alkalines in it, pull them out. If you don't, you are simply asking for trouble. You might get lucky, but the alkaline Russian roulette will eventually catch up with you.
