We are really happy, that now exist Lithium-Manganese batteries (LiMn), a special kind of Li-Ion. They have not the same big capacity of the normal Li-Ion, but the life time is much bigger (our warranty time for these batteries is 2 - 3 years).
NiMh dont like cold temperatures, they lose performance in coldness.
Only LiMn knows absolutly no "memory effect", they can be charged in each state of charge. LiMn batteries are the most safe kind of Li-ion batteries, they dont need any additional safety-electronic (balancer).
In the moment i think, LiMn is the best battery for diving lamps.

Hmmm . . . so . . . Lithium and sea water (or any water for that matter) . . .
I remember the demonstrations in Chemistry at school
