Please don't flame me, but I think if there is a true emergency for anything over 3-5 days those flashlights would eventually become unusable. AAA, AA, C or D size batteries are so much more prevalent. Also LED flashlights run just fine off of them.
Somebody explain to me why those Lithium battery powered flashlights are so hot? <img src="/images/graemlins/confused.gif" alt="" />
