I recently purchased the Optotronics Premium +150mW Green Laser and I was wondering what the best batteries are to use, for max output and burning power. I'm currently using regular Duracell AAA batteries and the burning power seems substandard.

PS: Optotronics was great in shipping and providing a great laser. I would definitely buy from them again.

I haven't personally gotten a chance to use them except in my weak 5 mW pens, but Sanyo Eneloops seem to be quite popular around here.

The voltage on Eneloops is obviously lower than that of alkaline batteries. In my CNI lasers, the Eneloops don't seem to give as much brightness. I should LPM and see exactly how much is lost.

Anyway, I wondered the same thing.. which alkaline works best, so I tested some common types. Hopefully you will find this useful.

energizer lithiums worked best for me

Energizer lithiums in my PGL-III-A 532 reduce the output! I tested it with fresh Enerigzer primaries (all I had on hand that were new) and got 80mW. Tested a little while later with Ultimate lithiums. It went up to 74 then started rolling down to 68-69. With the standard Energizer alkalines it's slowly ramped up to 80 and held there stable.

So anyway, some lasers will benefit from lithium primaries, and some will lose output. I have no idea why.

Energizer Lithiums are only made in "AA" size this guy was talking about his laser using "AAA" is everyone on the same page here ?

@ MIK were you using NEW energizer lithiums ? because I use them all the time and every once in a while I get a chance to compair them to other cells and they always come out on top for me ;)

Energizer makes lithium primaries in AAA.. where have you been looking? They have them just about everywhere here in Indiana.

In my particular example, I was using AA in the PGL-III-A when I saw a decrease in output. They were brand new, 2024 dated 1.8v. I don't think it's a problem with the battery cell. They are very powerful, and superior to alkalines. I think it just has something to do with how my particular laser deals with having too much voltage. I don't know what goes on inside of the driver, but obviously it is more happy with 3.0-3.2v than it is with 3.6v. Other lasers however, do perform very well on lithiums. I guess it just depends on the particular product.

Well doggone I musta had my head in a hole or something cuz I missed them, I get mine shipped stright here from Energizer so I don't buy them in the store if that is any excuse LOL
Thanks for opening my eyes :)
Have a fine weekend !

What do you use that many batteries for? I can't imagine using all of those even in 10 years.

I bought some cheap AAA 1.5V (Babies R Us brand :crackup:) The consistently put out 1.6V or higher and last a while in my Opto 150mW. LOL

Thanks for all the input. I'll try several brands to see which one works best.
Also, are rechargeable batteries the way to go, or should I just stick with the disposable?

I use disposeables. The rechargeables typically only make 1.2-1.3v, and it seems to reduce the output power of the laser too much for my liking.

If you read about the batteries that I tested, the Duracell ultra advanced was the clear winner in AAA moderate current draw performance. Your laser should draw as much current as mine, perhaps more. For that particular application, I would suggest the Ultra advanced. If you want, you can try the Energizer lithium ultimates as well and see how they work in your laser. They are the best primaries out there by far, but for some reason (as I mentioned with my PGL-III-A) some lasers don't seem to favor the extra voltage.

Rechargables have less voltage than primary cells so you are starting off at a dissadvantage.

@ Mik I use the "AA" in this light and in many others like it.

OMG, a full case of AA lithium primaries used on small flashlights? DAMN you must use small flashlights a lot!

Ever think about stepping up to 1x18650? Lots more capacity and current available, free recharges, and does not cost you a small fortune! The higher current availability & voltage also opens doors to more powerful diodes than you can run off AA.

These are just a couple of mine.. little one is a XP-G, optimised for throw.. bigger one is DD MC-E wide beam. It's a shocker to people who don't play with flashlights, how damn bright and wide it is for being in such a small body. Of course, neither of them have a low output mode, but there are lots of other choices out there that do multi-mode.

Hi Peaceshaker,
I would avoid the energizer lithium cells for our opto150 laser.
Two customers have reported to me that these cells for some reason will result in a maximum output of 125-130mw on the +150mw pen pointers while normal alkaline cells (duracell or energizer) will result in the full +150mw output. I'm not sure why this is, but I've confirmed this myself. You would think that the more expensive cells would be better, and they may power the pointer for a longer period, but they don't give as high an output power as a normal alkaline. It could be due to a difference in the internal battery impedance or current load.

Same thing I mentioned above that happens with my PGL-III-A.
