Ohk so i picked up my battery from the guy at batteries+ and he said the charge said 4v and i put it in my laser and it worked for a few seconds and cut off on high power again. and i just went with that because i felt i shouldnt take up anymore of his time. so when i got home i was able to use it again but it kept cutting off at random times not just high power mode and sometimes it wouldnt turn on at all but i managed to light one match with it and when i shut it off and went to turn it back on i got nothing. the LED lights did not turn on or anything. is this due to my battery? or is my laser broken? what can i do about this because WL does not return my phone calls.
