The capacity of a battery may be higher than its nominal rating. Thus, it is possible for the depth of discharge value to exceed the nominal value (e.g., 55 A h for a 50 A h battery, or 110 %). In most battery technologies, such as lead-acid and AGM batteries, there is a correlation between the depth of discharge and the cycle life of the battery.
The reserve capacity (RC) quantifies the time a fully charged battery can deliver 25 amps of current before falling below 10.5 volts. Higher RC means longer operation before the charge depletes. For instance, a battery with a 200-minute RC can deliver 25 amps for that duration. RC greatly affects the discharge rate.

BU-802: What Causes Capacity Loss? The energy storage of a battery can be divided into three sections known as the available energy that can instantly be retrieved, the empty zone that can be refilled, and the unusable part, or rock content, that has become inactive as part of use and aging. Figure 1 illustrates these three sections.
In conclusion, the battery reserve capacity is of utmost importance in renewable energy systems. It indicates the backup energy that can be stored and used when the renewable energy source is not able to meet the demand. It ensures a stable power supply and provides a buffer during emergencies or disruptions.
