rubbish. ordered on 3rd May 2017 for K3-II. very first charges were okay. didn't last as brand one, but did the job as backup. now the battery is just dying in my hands. freshly charged drops a bar after 30 shots. second bar after another 30. and gets worse with every charge. wouldn't take it with me even as a backup for existing backup.
