What kind do you stockpile? I want to build up my supply in a safe place...especially after I found that my wife had put my lithium AAs in our digital camera <img src="/images/graemlins/frown.gif" alt="" />

I found a good deal on some Rayovacs the other day. Which lead me to wonder what other people store...alkaline? lithium only?

The advantage of lithium of course is shelf life...disadvantage being cost.

What do you do?
