Depth of Discharge (DoD) is a measure used to determine what?

• A. The percentage of capacity used.
• B. The battery's temperature range during discharge.
• C. The cost per cycle of discharge.
• D. The max discharge current.

Answer: (B)

Depth of discharge shows how much of the battery’s usable capacity has been drawn down since the last full charge. It’s calculated as the discharged capacity divided by the total rated capacity, times 100 percent. This helps you gauge how much energy remains (state of charge) and plan charging, cycle life, and performance expectations. The idea about temperature range describes how hot the battery gets during discharge, not how much capacity is used. The other notions refer to cost per cycle or the maximum discharge current, which relate to different aspects of performance or economics rather than how much capacity has been depleted.
