By april 2018 i was increasingly disappointed with these batteries because i had already had a few individual battery failures

Once again the new batteries were not labeled before being placed into circulation with the existing 36 batteries

While the differing brand newness and external appearance had made it easy to recognize which of my old batteries belonged together there was no way to tell which of the new batteries had been purchased at what time

By midsummer 2018 the new batteries were failing at an alarming rate

Posted by a reviewer on Amazon

Returning to amazon to read the reviews i hoped to find out if other customers were having similar problems and to try to figure out if i had missed reviews discussing such a large failure rate

Posted by a reviewer on Amazon

But there were virtually no reports of failures let alone enough failures to qualify as a rate

Then it became clear why the batteries were failing at such a high rate the used batteries were apparently damaging the new batteries and or the new batteries were apparently damaging the used batteries
