I purchased 10 watch batteries on line. However neither of them work; one has voltage ~1V others below 0.7V. The expiry date is 09/2018. Initially I thought that something was wrong with my watch. Then I have just tested the battery and found that it had low voltage. After testing all of them I found that the whole bunch is faulty. I emphasise that there is still more than a year to the expiry date. Please replace the set. Best regards Arcady Dyskin
