I'm with Walt on the Duracell rechargeables, I've been using them (and other brands) in lots of things for about 5 years without any problems. I have some experience with Duracell alkaline batteries and just like every other brand out there, they leaked. If someone can find me a brand of alkaline that don't leak, please let me know.
The energizer lithium batteries I have in my remote now are about 3 years old, still have good charge, and won't leak when they do finally die. When the lithium batteries from energizer first came out, I gave them a run in my remote and they lasted about as long as a fully charged set of NiMH... and both types lasted significant;y longer than any alkaline I've ever used in them previous.
When it comes to expensive electronics, I really wouldn't run the risk ruining them with an alkaline battery made by (insert your favorite brand here).
