I had 8 trustfire 14500 protected batteries in a drawer for about one year. Now that I decided to check on them 5 of them had 3.97V exactly but one had 2V and two was dead (0V). What happened to the dead cells?
Why would some of the cells just rapidly self discharge now when they all came with the appropriate voltage when I bought them? :thinking: All the cells had about 1-2 cycles on them. I also have a bunch of 18650's, and they are all fine.
