Since they were counseled about a lot of pictures forums, I took my gun 8 420 EX flash. nothing to do with other brands, let alone with alkaline. I can do almost 300-400 flash pictures with 1 set of 4 batteries. apart, a battery, which remains under the announced values, others respect the announced values is 2550 mah mini ..certaines amount to over 3,000! By cons, it well you need a charger "evolved" with the "refresh" or "discharge" before recharging. the reason for buying the charger CROSSE TECHNOLOGY.
