    Program in the charger for Li-ion batteries can not discharge below 3.0V. For this test the cells of the discharging of Ni-CD or Ni-MH batteries because there you can manually set the threshold for exemption. As the measurement capacity was written from the 4.2V voltage until the cut-off by the security in the accumulator.

    Can you give Info on the size of those cells and the capacity to 3.6V ("empty") and 3.5V (already a bit under-discharge)?

    "15miki15" I think so too. It's strange but both batteries are >3000mAh.

    I tested again. 1A CC to 2.8V and this test give me 3010mAh.
