I do not use the battery in my Metz 48 AF-1 flash unit on the Sony Alpha 200. The perseverance of the batteries is amazing. I have already used many batteries of different well-known manufacturers, but here I was actually very pleasantly surprised! The batteries last forever, annoying battery change when shooting at parties etc come much less often before. Of course, many clippers must like me who sometimes firing lightning bursts, at least once in the evening to change the batteries, but other batteries I verballert one evening sometimes loosely 4 sets of 4 pieces and thus had 16 batteries rumschleppen with me. Now I take with 8 pieces of eneloops and good.
Unfortunately I caught the wrong dealer! Mobile Energy sent me the item quickly and easily, but: The batteries arrived loose! No trace of the promised in the article description Akkubox! Here it would have been very convenient!
