I'm currently in the processes of harvesting cells from used laptop packs. I am confident I have a hold and good understanding of the selection and testing process for selecting good cells. The one thing I can't decide on is cell temperature during these tests. I've a number of Panasonic cells that are reaching around 43 degrees Celsius at 1amp charge. Now these are obviously not too hot to touch and I expect some heat during energy transfer. I would like to get an idea of general opinion on this. Would you throw or keep. Is this normal?
