Lithium AAA batteries

[Ray_of_Light]

I understand lithium AAA batteries from Energizer are finally on the market, and their use in the Arc AAA makes a big difference.
Also they are, for the time being, very hard to find in retail stores and this situation, IMO, is going to last for a while.
Is Arc going to help and make them available for sale on the web site?

Regards

Anthony

You can order them from

http://store.batteryspecialists.com/l92bp4.html

for $8.99/4pk. No minimum, free shipping.

I ordered a pack, and got them in 3 days. /ubbthreads/images/graemlins/happy14.gif

TheProphet, the lithium AAA's don't make that big a difference in the stock AAA. They made an enormous differences in this_is_nascar's modded AAA which had a Luxeon running at much higher current than the 5mm led in the stock AAA.

I think if you consider it a big improvement or not depends on how you interpret this chart:

The question I have asked before and not received any kind of answer, is will the AAA lithium battery harm the stock Arc-AAA over the long haul?

Until this is adequately answered, I'm sticking with alkalines.

Peter already answered this, he said that the ArcAAA can handle up to 3v. The lithium AAA's don't really have that much more voltage (1.7v -vs- 1.5v). Their real benefit is capacity.

 

[this_is_nascar]

Peter already answered and said that it should not hurt the Arc-AAA on lithiums, since it's been tested to 6-volts.

Sean and TIN,

Thanks for the heads up. I must (obviously) have missed it, probably because I asked in the "Flashlight Electronics - Batteries Included" forum. Also, I hope Peter did not think I was slamming him or anybody else. I simply did not know he had previously addressed this.

Thanks again,
Mike

Ray, I agree that the ARC AAA circuit will be fine with an L92 lithium cell. I believe that you are mistaken about the 6V though. The circuit would probably survive but the attached LED would be toast. The only thing between the 6V input and the LED is a diode [about .3-.4V drop] and the resistance of the inductor [<1 ohm].

 

[this_is_nascar]

Maybe Peter said 3-volts. Regardless, it was rated at at least twice what the lithiums will deliver.

looks like a pretty significant improvement to me!

i wonder if anyone might be able to get a group buy gowing for a good price?

I just bought a pack...if my bank card goes through, that is. /ubbthreads/images/graemlins/smile.gif
Of course, the first thing I'll try them in are my Arc-AAAs. /ubbthreads/images/graemlins/grin.gif

The improvement according to that graph is:

1) For the first hour, slight brightness increase, not very noticable in practice.

2) For the next 4 hours, about 0.5 f-stop brightness increase, enough to be noticable but not a big deal.

3) After 5 hours, alkaline craps out. Lithium lasts around 6.5 hours.

All in all, none of this is a huge improvement. Winter is coming though, and I bet the difference will be a lot bigger in subzero temperatures.

Plus the shelf life. One of the advantages the Photon style lights have had over the Arc AAA is the long shelf life which is a consideration in an emergency kit. Putting an L92 in an Arc AAA makes it a great light to throw it your kit for a rainy day and not worry if the battery has discharged itself*. Plus, as you said, the cold weather factor. And, over an hour extra runtime isn't anything to snivel about either IMO.

1) I've clipped an Arc AAA w/L92 to my wife's car FAK for example.
2) Every once and a while I check the Arc AAA's I've given people as gifts. In more than one case, I've found the battery dead. I don't think this is due to use. Of course, it is possible they accidently activated the light, but on the other hand, the Arc AAA is pretty resistaint to that problem.

Arc's shouldn't be in rainy day kits. They should be used every day. /ubbthreads/images/graemlins/wink.gif

Don't tell me you haven't given in to the compulsion to buy more of these little goodies than you can carry! :-) You must find a rationalization for the lights you have purchased! :-)

SO far, I haven't find yet a dealer in Europe for the L92 battery, and none in the US that ships international. This is why I would like to know if Arc is going to put the L92 on sale on the website.

I run the Arc AA on lithium L91 battery, and I had no problem so far. I cannot recall what Peter once said about max voltage for Arc AAA/AA, but in my experience there are no damage incurring with use of lithium batteries.

I agree that the benefit vs. cost of using L92 batteries in the Arc AAA is not so great, but I have a flashaholic mind. A L92 has a more predictable behavior compared to an alkaline, especially for intermittent usage over extended period of time, do not stop working in cold environment, is less prone to leak, has a flatter output curve. The higher capacity is a marginal benefit for the use with the Arc AAA, I understand it, but the overall reliability, which is the only reason in life why I carry and Arc AAA 24/7, increases dramatically.
For my use of the Arc AAA, the running cost is of no importance compared to the reliability.

OK, lets' start the quest...

batterystation.com should have L92's pretty soon. They are just very new right now.

Bowing to peer pressure, I bought a 4-pack each of lithium AAA's and AA's from www.batteryspecialists.com (good price, free shipping). Those suckers weigh so little, they almost float away.
