All discharge tests shall be terminated at the supplier's discharge voltage limits. After discharge, the DUT shall rest at least for 30 min or shall be thermal equilibrated at the requested ambient temperature or a fixed time period shall be used to allow for thermal equilibration before starting the next step in the test sequence. The test procedure with the ambient temperature Tmin (−20 °C ≥ Tmin ≥ −40 °C) within step 34.1 to 41.3 in Table 4 shall be optional. NOTE Top off charge enables the DUT to be recharged in order to compensate for energy losses that can occur during temperature equilibration. 7.2.3 Requirements The following data shall be reported:
