I bought the coin-cell for my TAN generator, use for 3 x came again the message "Low Battery". I suggest packed up the remaining 9 batteries and measured, they all had a voltage of 2.6 -2.7 volts, this means at a 3 volt batteries that they are bad until completely empty. Thus, the whole delivery was useless for me. I wanted to then return the batteries to the sender for me for free, this one has unfortunately rejected me and pointed to the return procedures. I would have as a customer even the postage to pay for the return of unusable for me goods. Neither the sender nor the Amazon has been credited to my letter, you only sent standard answers that had nothing to do with my writing. I have disposed of the batteries and now my money depreciated. I'll take my batteries in future only buy in stores, even if they cost more there, for there will I still treated as a customer.
I am very disappointed.
If you read the other reviews here with only one star, one that I am not alone sees.
