1.5 years ago, I had already purchased 4 batteries of another variety of a different company at Amazon for the above phone, although not very long doing their service. Now a new attempt and what should I write, the batteries seem to be perfect for the Gigaset A58H. Anyway you can now re-run long telephone conversations without the batteries are empty. As the batteries prove themselves after a year, I know now Although not yet, but the time can I make a strong buy recommendation.
