As you should only use cells for 12 - 18 months from date stamped on cells (i.e. E7) you only have 6 months left on these cells. Given that most cells should only be a few months old when purchased, you should expect at least a year of useful life from new cells (faulty cells accepted)
Return them & get newer cells...
The total life expected on teledyne cells is 36 months from date of manufacture or about 1.5 years of use max..
I have received on mnay occasions cells that were 1 year old when purchased new.. Teledyne used to run large batches of cells and ship them as needed, now they run much smaler batches of cells...
The best batch of cells I ever had was from early 2004... I had some unused ones that were ust under 3 years old and tested linear to 2.0 even after that time... I just ended up binning the last of them in january.. the last 3 became limited to just over 1,6 for the worse and 1.7 for the best after about a year of use (and total time just under 4 years old!)
