Discharge duration should be a period of 10 minutes with no less than 7 minutes. What is the required discharge duration?

Explanation:
Discharge duration is the time the discharge continues. When a requirement states a specific target duration with a stated minimum, the target is the required value, and the minimum sets the lower bound you must not go below. Here, the discharge is specified as 10 minutes, with no less than 7 minutes allowed. So the required duration is 10 minutes. A shorter time would fail to meet the target, while longer times aren’t the specified requirement in this context.
