Yesterday i recieved my green 100 mw laser from lazerer and its great. Rated at 109 with 9 of IR. it burned and lit matches yesterday but today it wont burn anything. Why?
Not necessarily. If you notice a drop in power then pop it in the charger and you are good to go. Just don't overcharge the battery. Although the charger will automatically stop chrging once its full, it's not a good idea to leave the battery in the charger all the time.
