One of the battery is detected by either the camera or the charger, the other worked until I have just made the camera and 30% were gone within 10 minutes, without any use, the camera was only at the table ... Battery Charger into, continuous flashing as in other battery ... The battery grip itself is well located, but it came from the attachment before increasing that the camera for a short time off, as if the batteries no contact or the like. This issue has never before occurred Return is unfortunately impossible, since this is only possible within the first month. Therefore 1 star from me for 2 defective batteries and a defective battery grip
