The required test consists of the following steps:
1. Test is performed at room temperature. If the cell was at a different temperature , let the cell relax for
two hours at room temperature prior to the test.
2. Charge using CC or CV charging to full using taper current. (For example, C/100.) Use nominal CC
charge rate and CV voltage. If another charging method is specified by the cell maker, use that
method.
3. Let the battery relax for two hours to reach full equilibrium open circuit voltage (OCV).
4. Discharge the battery at C/10 rate until the minimal voltage (as specified by the cell manufacturer) is
reached.
5. Let the battery relax for five hours to reach full equilibrium OCV.
