Hi i received this lazer LZBH - 532nm 100mW Focusable Green Laser Pointer from lazerer.com i used UltraFire BRC 18650 3.7V Rechargeable 4000mAh Li-ion Batteries Battery and i used the charger that i got given from them as well. I fully charged both the batteries and they wernet able to melt a hole in a black bin bag or even in a clear wrapper and nothing. The Power certifacte that i got from them said that it was maxed at 105mW and stable at 105mW and the IR output is 10mW. Could it be that the batteries don't have the right amount of power as stated or is it the laser ? Should i buy some different type of battery to test ?
