[QUOTE="spb_stan, post: 677314, member: 43545"] Are you not getting enough flash cycles out of a charge. If so, battery current rating might not make any difference. If you are not getting 350-500 flashes from a set of you might be causing full dumps. Even a small increase in fixed ISO can double your battery life in a session, I regularly take 500 flash shots with SB-900s in events and don't have to replace batteries. I have used both the Eneloop Pro and regular do not see much if any difference in SB900s or Yongnuo flash units( 6 of them in my bag). Regarding chargers, after getting the tech application notes for the OEM version of the Eneloops I tried my lab bench programmable power supply to see about faster charging but seeing the current limiting controller built into each battery, I found I only saved about 8-10 minute from zero charge to full charge when compared to my cheapy 8 bay charger. Overall, battery tech has progressed so far ahead of just a few years ago that a set fully charged should not need replacing or recharging for any all day event or wedding.. For those needed full dumps,a tandem bracket for two or more flash heads is a better solution than getting the expensive optional tethered battery pack for the SB-9x0 series. Full dumps are hard on the temperature rise time getting very shot on SB910s and 900s. I have never had one overheat but talking to wedding photogs in high ceiling churches it is reported it is common for temp shut down. Moving to ISO 200 from 100 should resolve that, or using a little larger aperture....(if the place is that big, getting back a little increase the depth of field so a larger aperture keeps all the subjects in focus), but controlling light dispersion will have more effect for the good and extend battery life. The biggest improvement in flash power to the desired place it getting an assistant with a light pole and flash mounted on it. Amazing difference in light control, and exposure consistency even in full manual exposure as most event shooting uses. Regarding life of Eneloops, I have 12 sets of and them all perform the same, no dropoff noticed on the oldest batteries, white or black, they are all really good and hold a hard longer than any others I have tested.
