|---|---|---|
BatteryManager.chargingTime | double (float) | The remaining time in seconds until the system's battery is fully charged. Returns 0 if the battery is fully charged. Returns positive infinity, if the battery is discharging or if the implementation is unable to report the remaining charging time. Read only. |

console.log("Battery charging time: " + battery.chargingTime + " seconds");
battery.addEventListener('chargingtimechange', function() {
console.log("Battery charging time: " + battery.chargingTime + " seconds");
});
