DX Lasers: Don't use the batteries!

[Revolvr]

I got a 50mW DX laser today - quite happy with it.

But, I initially used the cheapo Chinese alkaline AAA's it came with. After a few minutes - of not using the laser, I noticed the barrel getting very hot behind the power switch and the laser was dead. I pulled it apart and dropped the batteries. One of them was almost too hot to touch. Must have had an internal short.

Swapped out with Energizers and no problem.

Lesson learned - toss the DX batteries!

Otherwise this laser is great. It burns better than my BFG.

Dang - I too had an issue with the cheapo freebies included....I actually got them STUCK inside the battery compartment - and out of frustration ended up destroying the battery compartment to get the damned batteries out ! Well, I now have a super nice module to use hehehehehe (DOH !) Lesson learned - take your time, and don;t rush things !

When you point your laser at your hand, do you feel any heat?

Reason i ask is, i received my 5omw yesterday and it does not burn a thing

from my cheap ebay 50mW i feel slight warmth on my palm from the laser but if i put a black dot on my hand and shine the laser on that its quite painful.
