I am also concerned by a batch with the high rate discharge. Here is, according to information on the support hotline really a production error. Faulty batches can be recognized that in the blue region (very difficult to read) the letters "WH" are stamped (if possible, however, other combinations of letters concerned). Contrary to what some posters here that on the Varta Homepage no phone number was given all the necessary data are in "contact" can be seen. For those who do not want to search the telephone number is given: +49 (0) 7961 - 83 77 0. one call there and faulty batteries be replaced quickly and efficiently, it also will not be charged. Hence my rating of 3 stars, the batteries from the defective batch did not even deserve a star but the excellent customer service makes up for that. Packages to say, Varta batteries would crap is not appropriate in any case (see other sizes and capacities of the manufacturer). And if you are now ordered these batteries no longer affected by the problem because the defective batches have now been withdrawn from the market.
