Battery capacity is measured in mAh.

Explanation:
Battery capacity is measured in mAh because it represents the amount of stored charge. Milliamp-hours quantify how much current a battery can deliver over time, so a higher mAh means more charge and typically longer runtime for the same device draw. For example, a 3000 mAh battery can supply 3000 mA for one hour, or 1500 mA for two hours, assuming constant voltage and efficiency. In real use, runtime also depends on how much power the device uses and the battery’s voltage, so energy content is sometimes expressed in watt-hours (Wh) to account for voltage differences. But in common practice, stating capacity in mAh is the standard.
