-- Everything you ever wanted to know about Batteries (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=698)

While wandering the ether I came across this excellent battery FAQ. Although written with digital cameras in mind, it is 100% applicable to Visor users (and anyone else that uses batteries). It is well written, and explains the different types of batteries - Alkaline, Nickel-Cadmium (NiCd), Nickel-MetalHydride (NiMH), and Lithium-Ion (Li-Ion) - their strengths and their weaknesses.

If you have any questions about batteries, follow this link: http://www.olfe.demon.nl/minolta/ and choose "battery FAQ" from the sidebar menu.
