This occurs since, particularly for lead acid batteries, extracting the full battery capacity from the battery dramatically reduced battery lifetime. The depth of discharge (DOD) is the fraction of battery capacity that can be used from the battery and will be specified by the manufacturer. For example, a battery 500 Ah with a DOD of 20% can only provide 500Ah x .2 = 100 Ah.
Battery load testing provides an accurate measurement of a battery capacity, furthermore, it is the only proven method to measure the capacity and determine the state of health of a battery. …
