If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour. In other words, you can have "any time" as long as when you multiply it by the current, you get 100 (the battery capacity).
What is the difference between charge level and battery capacity?
Where: Battery Capacity (Ah): The amount of energy the battery can hold measured in Amp-hours (Ah), milliamp-hours (mAh), or watt-hours (Wh). Charger Current (A): The charger’s output current is typically measured in Amps (A) or milliamps (mA). To consider the current charge level, we multiply the battery capacity by the uncharged percentage.
