Typically battery manufacturers only run life cycle tests at 100% or 80% of energy capacity. However utility cycles can also involve depth of discharge cycling that mix moderate (20-30%) depth of discharge combined with many small (<1%) depth of discharge events. Partial state of charge test patterns must be used to augment the full scale depth
