Ah Efficiency

In particular, columbic efficiency (or Ah efficiency) represents the amount of energy which cannot be stored anymore in the battery after a single charge–discharge cycle [23,24], and the discharge efficiency is defined as the ratio between the output voltage (with internal losses) and the open-circuit-voltage (OCV) of the battery [25].
