I bought these batteries 2 pieces together with the counterfeit battery grip. The battery grip is still OK, but these batteries, the first really made a positive impression (apart from the fact that they are a little too thick and I get it from the K5 with a side-mounted tape out), Been to the ( about) the tenth charging actually only for the battery container. Both the K5, and my gauge confirm that there is actually nothing is loaded. Sorry!
