Primarily a use as a backup for the existing original batteries was intended. The shipment was due to Prime as always perfect (MarketPlace dealer on Amazon). The battery is no "protective plate" for contacts / bottom as with the original batteries in, but that's to get over.
Both batteries register easily in the camera (5D Mark III with current firmware). Both directly and in the battery grip. Here no difference is discernible. The charge indicator outputs meaningful values.
The first 2 shootings resulted in about the same endurance as the original batteries. Also charging works flawlessly and in the same time frame as the LP-E6. But after a few other uses, I had the subjective feeling that it was now less and the number of possible triggers for similar usage profile has continued to decline.
Now, after about 8 months, and about 10-12 charges the endurance has again worsened dramatically. After charging and insert into the camera a capacity of 100% is displayed, but after a few trips (10-20) the batteries then fall rapidly to 70% (parallel operation in the original battery grip). The batteries then provide no more tripping 100 and will not be compared to the original batteries in practice. Not even considering the really good price which is paid here on a malfunctioning product.
I (Eneloops etc.) to other equipment in addition to possess the original batteries and the corresponding charger or various other batteries and fitting charger and this perfectly do their job, I assume that it is not due to a faulty supercharging strategy on my part.
Too bad, but the experiment Third Party battery is finished for me with it, although I do not operate the photograph to life underflow.
