I just ordered an aries 20 from laserglow

would it be better for me to use rechargable batteries?
im sure it would be cost-effective but would it shorten the life of my laser at all?

Laserglow recommends the use of regular alkaline or NiMH rechargeable batteries in the Aries series. NiMH batteries will work just fine and will not affect the life of the laser.

The best results I've had with my lasers have been with Energizer Lithium batteries. Theyre not rechargable, but they last forever and the power doesnt decrease nearly as fast.

Note that if you want to use the energizer e2 lithiums in the Aries series as 360freak suggests, you'll have to get some AA to C converters. They're essentially just little plastic C-sized cylinders that you can insert an AA battery into to make it have the physicl dimensions of a C-cell. I picked a pack of four of these at my local Fry's. They were made by Lenmar. My only beef with them is that they were actually a little thicker than a normal C cell so I had to sand them down to get them to fit.

Note: I asked Laserglow specifically about using the e2's in the Aries series, and they told me that while it would work and probably not cause any problems in the near term, it might cause earlier driver or diode failure since you'd be overdriving the diode slightly. The current regulator is apparently designed for a maximum of around 3.4 volts, and two e2 lithiums in series produce about 3.6-3.7 volts.

By the way, you'll love the Aries when you get it. The fit and finish of these units are fantastic! In fact, the only problem with the Aries 20 is that as soon as you get it you'll instantly want to buy a higher-powered version because you'll be so impressed with the lower-powered version!

you can get rechargeable liths...

you could get one 14500 Lithium rechargeable from dealextreme (AA size) and put a blank wire through the other AA to C adaptor as those batteries put out 3.6-3.7V.

NiMH's are great, but get ones with the highest mAh capacity you can find. 2800+ for AAs and 6000+ for Cs.
The only downside to them is self-discharge,
NiMH historically had a somewhat higher self-discharge rate (equivalent to internal leakage) than NiCd in the past. However, this is no longer the case. The self-discharge is 5-10% on the first day, and stabilizes around 0.5-1% per day at room temperature. ... The rate is strongly affected by the temperature at which the batteries are stored with cooler storage temperatures leading to slower discharge rate and longer battery life.

so if ya leave 'em sitting for three to six months they're "dead".
Make sure they're charged before you want to use them!

There are low self-discharge NiMH batteries too, only 25% discharge after one year on the shelf. But right now I think you can only get them in AA and AAA size.

The best combo is NiMHs with lithium back-ups.
C NiMHs 'cause they can be recharged hundreds of times.
AA Lithium (with adapter shells) back-ups 'cause they've got such a long shelf life with no charge loss.

i don't think lithium batteries are rechargeable though..

They are, my cell phone has a 3.7v 1100mAh rechargeable Li-Ion battery.
Ya just can't get them in the "standard" letter sizes (AA(A), C, D). You can get them in 9v and CR-123A, 123A's being very popular for tactical flashlights.

I, at the recommendation of BlueFusion, bought some Duracell Powerpix 1.5v NiOx (Nickel Oxy Hydroxide) batteries for my Wickedlasers Fusion. Up until now I was using rechargeables and was under the impression that my laser was pretty much worthless for any kind of burning or popping or lighting. Not so anymore. Now it actually outputs a decent amount, maybe even at spec. Too bad the lens is so scratched it looks like a giant halo around the dot:

Which battery works best will also depend on the regulator the laser uses. There is no difference in output with my Nova laser whether I use nimh's, rechargeables, alkaline or even e2 lithiums. We had quite a discussion about it here:

There is a lot of good information in that thread if you want to read through it.
