Yes, that's them thanks. Of course you said alkaline in your original post, but I just remembered the zinc bit ! I had batteries that leaked before. Must watch out for that now.
I've just checked all the batteries I have in the battery drawer, most are Duracell and say Alkaline, none say 0%Hg or Cd, does that imply they have these elements?. I imagine not having those elements is a good thing for the environment.
Any idea of the most environment friendly batteries with good performance? I had some rechargeable ones once and they were a waste of money.
