The ideal battery for all applications, whether camera or flash. No memory effect, extremely low self-discharge, stable in the long term. There are no surprises because "pötzlich" low batteries when you need them. Reloading partially empty battery pack for photo series for the next job is not a problem, it is always the full power available.

I do not measure the dead battery, I servicekit Change quickly to full. It is therefore appropriate to carry two or three battery packs per device in the suitcase. One must not be irritated by the "only" 1900 mAh capacity. This battery lasts longer than most "normal" with 2700/2800 mAh, which clearly fall after a few charges already. But there are also now available from other manufacturers similar batteries, but more expensive.
