2. Change the battery.
If the battery is put well in place but the laser does not work, it may be low powered. So please try to change the battery.
  • Please check the battery mode coming with your laser, if it writes 16340, please search for the 16340 3.6V or 3.7V battery 


  • If it writes 14250, please search the 14250  3.6 or 3.7V battery

14250 3.6V:
