writing on your batteries...

Default Re: laser being hot batteries

Sounds kinda like the spring on the base of the driver is shorting the Batteries to the case. open er up, pull the batterier out, look down the barrel at the spring to see that it is or is not touching the barrel (inside od the case). If it is, try to push it away from the barrel with something like a pencil, and/or try to insert a rolled sheet of paper between spring and barrel. Might not be the problem, but is a common problem with cheap pointers...

Actually had that happen with a cheap greenie. Batteries got very hot, very fast. One loop of electrical tape around the inside of the barrel, where the spring is, solved the problem.

Yeah... that Laser should not be pulling any current
near what it would take to force the batteries to
get hot..

You could also roll a small piece of paper that just fits
in the laser housing to insulate the inside of the barrel
from touching the spring...
Be sure the insulator is thin or you may have problems
removing the batteries..
