Review: measured capacity & energy

  • DrJones Sunday, February 21, 2010 4:11 AM Reply
    I measured their capacity and energy and got
    2442mAh/8509mWh for one cell, but only 1768mAh/5929mWh for the other.
    The weaker cell was about 1mm shorter, so they probably are from different batches. It just might have been bad luck... but others seem to have similar experiences.

    Testing conditions: regulated constant discharge current 2A, external shutdown at 2.9V (protection circuit's shutdown is lower).

    Here are the graphs:

    I have gathered some more info and a comparison on http://lux.yi.org/batt/.

    Good job. Look inside the battery, below the outer sleeve, and you will see a "2200 mAh" print...
