That just means that the one cell was defective if nothing was hooked up to it. Just like in a video I watched today of Lipo cells being manufactured. The last step of the process is charging them up and letting them sit for several days. They said that the longer they sit the fewer defective cells make it out the door. They test V and IR to see if any cells are bad. If you have a LiFePO4 cell which self discharges then it is defective. As others have said, Buddy, just leave your cells alone in a cool dry place. If you find one which has discharged then be glad you found out before putting it in your car. They should have no measurable self discharge. -- David D.
