1. first try another battery!
2. f that won't work it's probably your driver or your diode. (More background information would be helpfull!!)
3. Disconnect diode and test the driver with a tesload if thats works it is the diode that is toasted. REMEMBER before you re-attach a new diode short the driver output leads! as a voltage spike can kille your new diode!
problem solved!

If your battery is fine and your driver is fine, it must be the diode. If its emitting a dim glow that means you've LED'd it. That means its giving even over driven to the point of failure or overheated. The heat could be due to a prolonged duty cycle or soldering damage while making connections. Either way your question is kinda self answering. If a diode is broken will the laser not work. I always thought if something is broken that means it does not work :thinking:
The laser does work fine for 20 or so minutes, extremely more powerful than other 200mw lasers i've had!
then after a bit of prolonged use, i.e. burning, it starts to fade to a dim dot! Thats on a battery thats fully charged. If i then charge battery again for 20 mins until the charger light goes green, its ok again for a while!
The laser is brand new from o-like.

woudn't that mean that the battery is simply discharged
20 minutes on is quite a while. And some cheap batteries may just last that long.

Well i probably mean 20 minutes of use spasmodically, not 20 mins straight!
If i am burning & i hold the laser on for a while, say periods of 30-45 seconds on, it happens then too!
I used the same battery with my old laser, the transformable 200mw from o-like & the laser never dimmed then!
Are you ruling out issuesswith the driver & diode?

I think you should contact o-like's customer support. They should replace it.
This lase is a replacement for a laser i sent back. I don't want to send back if its just a fried battery.
I'm just wanting to know if it is a diode or driver problem, would the laser work at all or for even a few minutes with ok power! I thought if anything within the laser eg. diode or driver, it wouldn't work at all !

Try to find another battery like this one if it does the same send it back.
I hear chargers or quality of battery can make a difference!

If you were prepared to wait a little for shipping, LarryDFW's charger is a great little 18650 charger and very well priced ($9 - £6); we get ripped off for everything in the UK. It charges to 4.2V everytime (so far ) His Samsung batteries aren't bad either. (about half those amazon prices)

18650 Batteries & Chargers
Apart from that, X-TAR WP2 USB charger (about £12) or Ultrafire WF-139 rapid charger (£20) aren't bad choices i.m.o

hmmm., if the driver lacks the reverse polarity protection you might have fried something. But as it still working - even for a little while.. I can't be sure...
