Arduino program showing data from DS1302 clock on 4-digit display

ArduinoDisplayClock.ino

#include <virtuabotixRTC.h>

#include <SevSeg.h>

SevSeg sevseg;

// Clock DS1302 on analog pins 0 to 2
virtuabotixRTC myRTC(14, 15, 16);
 
void setup() {
  byte numDigits = 4;
  // 4-digit display HS420561K-32 on digital pins 2 to 13
  byte digitPins[] = {2, 3, 4, 5};
  byte segmentPins[] = {6, 7, 8, 9, 10, 11, 12, 13};
  sevseg.begin(COMMON_CATHODE, numDigits, digitPins, segmentPins);
  sevseg.setBrightness(90);

  // Comment out on second run if clock has 3V battery.
  myRTC.setDS1302Time(40, 13, 23, 3, 11, 2, 2016);
}

void loop() {
  myRTC.updateTime(); 
  sevseg.setNumber(myRTC.hours * 100 + myRTC.minutes, 2);
  sevseg.refreshDisplay();
  delay(10); // Optional, to save power.
}

Hi, sir i just tried out the code and its working partially.When I disconnect the Arduino from the power and connect it again the time resets and shows the default value on sevseg.How can I solve the problem?I bought a a new 3v battery but that wasnt the problem. Anyway thanks!
