The capacity of the battery is represented in terms of Amp-hour.
The capacity of battery = current delivered × duration of time
Battery capacity unit mAh means when 1 mA of current is drawn from a battery it will take 1 hour to discharge.
Calculation:
The capacity of battery = 4000 mAh
Current delivered = 4 A
\(Duration \ of \ time = \frac{4000 \ mAh}{4 \ A}\)
\(T = \frac{4000\times10^{-3}h}{4 \ A}=1 \ hour\)
T = 60 min
