I have a green laser pointer pen but every time I use it, it always run out of power and i decided to buy a new rechargeable battery, which will improve the laser efficiency. if i have a 3.7 v battery the size of AAA, and another completely discharged battery, it might improve the laser power output (not the actual power output but i think the light intensity)
