Has anyone tried rechargable Li ion CR123A's available at Battery Junction in the F6? I have used them in my light meter, SU-800, and SBR-200's and they work very well. Good Luck and ZZEnjoy your Nikons
I have 4 rechargeable LI's that I bought from B&H a few years ago for use in the R1C1 system. They work well when fully charged, but don't seem to hold charge well for extended periods of unuse. They are WAWA brand.
I pick mine up at Lowes, a two pack of the Lithium CR123A's is about $ 5.00 I hate to buy too many by mail because I don't know what the shelf life is. So far I have shot 4 rolls of 36 with the first pair.
