Operating voltage and maximum current Battery voltage differs depending on the combination of active materials used in the positive and negative electrodes. In practical operation, battery voltage varies depending on the load (or discharge current) applied. When the load resistance becomes smaller (or discharge current increases), the terminal voltage (operating voltage) and the battery capacity decrease. These values differ according to battery type and tend to be lower at low temperatures.
