150mw o-like module battery choices

[zxn474l]

I just ordered an O-like 150mw 532nm green laser module and I was wondering what are the best battery choices for this laser module for maximum mw output as well as lasting longer? Can I use 2 AA lithium Enegizer batteries that would be 3.4 volts and around 2500ma plus on the amperage side, that should last the longest right? I have heard of people using cr123 batteries...what about a fully charged 18650 battery at 4.2 volts, that should be the longest lasting and rechargable....Somebody please let me know if you have experience with this module and use it for a burning laser. I don't want to damage the laser module. Also the "spring" is negative...and the case is positive? Yes or no?

you can use the ff; this worked with me,

either a CR123a 3.0v or 3.6 or 3.7

2 AAA batteries rechargable or not

2 AA batteries rechargable or not

1 10440 battery (3.7v)


there..

I haven't yet ordered that module (but will), so I'm wondering that too.
Just ordered these:
DealExtreme: $4.50 17340 / CR123A Rechargeable Lithium LiFePO4 Battery 2-Pack (350mAh)
Look good: 3.0v, never explode, up to 2000 recharges (vs 500 for Li-ions), true capacity, work with the charger that I have (DealExtreme: $11.54 UltraFire 3.0V/3.6V CR123A Charger) and reviews are very positive.
What d'you say?

I like these:

DealExtreme: $4.91 UniqueFire Protected 16340 3.7V "880mAh" Lithium Batteries (2-Battery Pack)

protected, and higher capacity.

Also, this charger works well for me:

DealExtreme: $8.81 TrustFire All-in-One Charger (for 10430/10440/14500/16340 /17670/18650/CR123A)
