My 445NM Blue Laser is having problems I can't diagnose. I've brought new batteries and a battery charger. I charged them all the way and the light beam didn't even make a dot on the wall it was like the batteries were dead. I was 16340's 1.8A Mohgasm Driver, M-140 Diode. I don't know why it is acting like the batties are dead. Could it be the driver?
