The BatteryManager.chargingTime property indicates the amount of time, in seconds, that remain until the battery is fully charged or 0 if the battery is already fully charged. If the battery is currently discharging, its value is Infinity. When its value changes, the chargingtimechange event is fired.
Note: Even if the time returned is precise to the second, browsers round them to a higher interval (typically to the closest 15 minutes) for privacy reasons.
A number.
