Battery question.

[p3rs0n]

Sorry if this has been asked before, I just couldn't find anything.

I bought this laser:

$18.60 - 100mW 532nm Green Laser Pen (2*AAA) - Green Lasers

Will these batteries fit into the laser? (I know they are 1-2mm longer than normal batteries.)

$5.13 - TrustFire Protected 10440 "600mAh" 3.7V Rechargeable Li-Ion Batteries (2-Pack) - Batteries

Would it be possible to ruin the laser with these batteries?

Is there anything else i should know about using these batteries?

Thanks in advance.

You will most likely kill it

Then I probably won't be buying those.

You could use one battery and use a spacer or shorten the lasers barrel,
or you could use 2 of those batteries if you put them in parallel instead of series.

Then i'd have 3.7V instead of 3V, if I still remember my physics correctly.

I guess it would still stress the laser a bit more.
Would that then be safe?

And when using only one, the battery wouldn't last very long, i'd guess.
