Hi all ! Lately i've used quite a bit my SB80-DX wireless slaved, all manual, full power, for some macros... During a 80 shots session i had to change 3 times the 4 AA batteries ! I have 2 sets of 1300 and 2 other sets of 1600 mAh. I noticed that i get about 30-35 full power flashes out of the 1300 and about 35-40 out of the 1600 mAh... I checked all sets, they are in good conditions and i allways recharge them on "slow"... Is it normal that they get empty as fast ? Thanks in advance, J-P.
