I am buying my wife an orange Streamlight Survivor LED with alkaline batteries (without the charger) as a Christmas gift for my wife. The idea is that it will be kept in our bar where the most common uses will likely be looking for our horses at night (sometimes they'll stand quietly in a dark corner of the field) or searching for problems with our electric fence at night (sometimes when a large bird lands on the electric wire it gets pushed down and catchs on the mesh fence, which grounds it out).

Anyway, since it gets way cold in the barn, I'd rather use lithium batteries than alkaline batteries, but the Streamlight description specifically lists the Survivor LED as using alkaline batteries. Do you see any problem with swapping out the alkaline AA batteries with lithium AA batteries?
