Arrived by USPS in ordinary envelope. The automatic mail sorters kind of squish the packaging so the delicate foil back behind the battery may be split. I checked all voltages and they were all viable at this time. A couple of the battery voltages were a few millivolts lower than the others. Into the refrigerator until I change battery in about one year. Keeping them cool slows the chemical reaction a bit to prolong life in storage.
