I have never used lithium batteries (the non-rechargable kind, AA) before.
I'd like to find out how effective they are in comparison to a regular old alkaline, from someone who uses them (or has in the past) .
Could you tell me:
1. What light you use them in
2. How long the lithiums provide caving-usable light
3. How long alkalines last in the same setup
Your responses (if any ) will be a big help to me. And be much appreciated.
