Ill keep an eye out for NiZn batteries you mentioned. But meanwhile what is a flash's default battery rating. I mean the company usually mentions the battery rating such as 1.5v or 1.2 right ? Whats the rating printed on your flash head please ? Mine doesn't say, since i work with a bunch of yongnuo's
but im guessing most of these things are rated for 1.5v batteries as a standard. But then many of them will make do with 1.2v except for the fussy ones.
The chemical combo on the rechargeable alkalines im looking at says zinc manganese, ZnMn, wud i be ok trying to recharge these on my intelligent NiMh charger ?
