The memory effect of the battery is written in a cycle with partial charging (here, 50% of the battery’s storage capacity) followed by complete discharge. In the subsequent cycle, the memory effect is evident through an overvoltage (small “bump”) at precisely the same point at which the partial charging cycle terminates. Sasaki et al.
