Some information about lithium batteries. Lithium batteries are used in
the film and video industry by serious professionals who work in very cold
conditions. Lithium works well in very cold conditions, nicads and
alkaline batteries do not. Lithium batteries have a shelf life of ten
years; they are made for motion picture cameras and video cameras. I have
three lithium batteries for a Sony VX3 camera that fit in an Amphibico
housing with the camera. They have a performance life of eight hours at
temperatures of Arctic waters. The lithium batteries that I use do
not give off any discernable gas. There is a company in Massachusetts
whose sole existence is devoted to making lithium batteries for the film
and video industry. They also make other chemical batteries that are
rechargeable using conventional charger or solar charger. Solar chargers
are useful for remote expeditions that are not going to hump a generator
nor carry hundreds of non-rechargeable batteries. E-mail me privately and
I will give you a phone number if interested. Rod
