eBay.ie: CR123A Rechargeable Battery+Charger CR123 R123 1800mAh (item 320583051402 end time 28-Sep-10 18:16:44 BST)

or

Rechargeable Batteries: Sports Linkup Shop : Rechargeable Batteries

maybe other places have it. I made a google search Rip. I do this often to keep an eye to the progress of battery's development

the second link has 2000 mah too

you can always just pencil in another "0" to the 500mAh batteries, because in that size cell, with that chemistry, it's about all you're going to get.

We dont know that for sure byGG. Batteries are getting better. The only we have to do is to buy them and test them. Rob can do that and I can do that but I have to order them first. I will order tonight.

I read the review about the GTL 1800mah batteries in the candlepower forum. And all they got out both GTL together was 700mah... Kinda sad about false advertising... China battery companies do that all the time.

I see Rip. Did you read anything about those 2000 mahs?

by all means, order them...but if you are looking at a 16340 cell, at 3.7V, order an AW IMR16340, and if you are looking for 3/3.2V cell, order an AW LiFePO4 cell as well. They come closest to the actual mAh runtimes of the cell, and more importantly, they are the only cells in that size that have maximum continuous discharge rates to feed the amp draw of any atomizer we may use. all of these 2000 mAh, 1800 mAh, 900 mAh, and 750 mAh cells in the 16340 lithium based chemistry are a joke, and on top of that, whatever their real mAh runtimes are, these cells become further reduced by the amperage draw from the atomizer, they become susceptible to voltage sag, and they will undoubtedly have their overall life cycle reduced. the two AW cells i mentioned simply do not have this problem. their runtimes, and those of many other cells, have been tested by hobbyist and enthusiasts whose uses and applications for these batteries go back much further than our own. the hyperbolical cells you mentioned may be sufficient for some applications, but if we want to feed the atomizers proper voltages, for as long as we can, with a particular size configuration, as safely and as consistently as possible, we are limited to very few batteries.

for your GGTS the following cells are really the only cells that will offer the maximum continuous discharge rates while delivering the longest possible runtimes irrespective of the atomizers we use:
AW LiFePO4 500 mAh(3.2V) ...the only 3/3.2V cell with a max. discharge to handle the amp draw of any atomizer when stacked in series
AW IMR16340 550 mAh (3.7V)
AW IMR18500 (AW IMR14500 would work, but because the length is the same you may as well use the 18500)
AW 18650 (Protected cells in 2200, 2600, and 2900 mAh that have the requisite drain rate so as not to necessitate LiMn chemistry)

order some of these, charge them properly, and "test" them against whatever other cells you can. this is the best there is for our purposes right now, and when improvements are made, they'll likely be from the same manufacturer, not GTL or ****fire, Tenergy, or others who are currently misrepresenting their products, but rather by those who have strong records of quality control and who have consistently been producing the best cells, maximizing their size and chemistry limitations, for a while.

Tenergy 750mah cr123a's lifepo4(yellow/silver wrapper) ... the Lifepo4 ones seem to last me a good amount of time.... plus they recharge cycle is soo much... like 2000+ cycles vs. an average of 500 cycles on the Li-ion cr123s ....

I agree with BuGG;
the AW is better in a sense that they put out a steady 3volts vs Tenergy, UltraFire, etc; have a voltage sag...

I forgot the thread I saw in the candlepower forum where they did an extensive research on the aw ...

So, are you saying you don't like LIMN batteries from AW for the GGTS? I currently have the AW 18650 1600mah, and I feel they work great. Can you explain further on the LIMN batteries vs LiCo? I prefer a battery that doesn't explode with fire, but I'm all ears.

no i'm a big fan of the AW LiMN cells, but for vaping, i find that they are only of any real meaningful value to us in the 16340/CR123A and the 14500 sizes. what i mean by this is more a concern over having a cell that can safely handle the amp draw of the atomizers we are using. prior to the introduction of the LiMN cells, this was not the case in most setups, not just with low resistance atomizers, with the exception of the LiCo 18650 size cell (and the rare PVs designed for 17670 or 18500 cells). now LiMN is still lithium ion and it can go poof, but no oxygen production means no flames. all batteries need to be used, charged, and maintained carefully. much of the concern surrounding cells exploding in the past centered around unprotected cells (yes, LiCo) and stacked cells (running them in series). stacking cells, should in theory double the voltage which also increases the amp draw demanded from the atomizer (amp draw =voltage/atomizer resistance in ohms). this increased drain rate placed on the batteries quite often exceeded the capacity of the cells causing voltage sag, lower runtimes, increased likelihood of over-discharge, and very demanding strain on the cell beyond its intended use. bad things happen here, but there is also a good chance that these cells weren't being used properly, weren't both equally charged to begin with, had been over-discharged and recharged, possibly overcharged, etc., and were otherwise damaged to begin with. all of this is a recipe for disaster...not a guarantee but an increased likelihood.

the protection circuitry, or pcb, of the AW batteries is as good if not better than any. however, going any lower than the 17670 cell, means that you can't provide the continuous discharge rate of a 2.3 ohm standard Joye 510 atomizer, and it gets worse when you consider using 1.5- 2 ohm low resistance atomizers....the lower the resistance, the higher the amp draw and the drain rate placed on the battery. so when the IMR became available to us, with drain rates fitting our applications, we jumped on them. the safer chemistry amounts to avoiding the risk of poisonous gas inhalation, nasty burns, and self-feeding flames...all of which can arise from LiCo cells, but again, these are risks that more often than not come into play with improper application of the cells (using them with loads more demanding than they are able to safely handle), improper maintenance (allowing the cells to over-discharge beyond safe levels), and improper charging (allowing the cells to over-charge in some cases beyond 4.2V, etc.). good protection circuits like those on the AW cells shut it down before the cell over-discharges, and cap it in the unlikely event that the cell could potentially be over-charged. without these protections in place on LiMN cells, the risk of it blowing up in your face is not there, but ruining the cell from improper use still remains. all i'm saying is that respecting all of these batteries is the key, knowing the load you demand of them, knowing their voltages when the vapor drops off, after charging and even at rest, visually inspecting your batteries for abuse or damage, and knowing when it's time to throw them out, when it's time to charge them, and doing the little things like preventing the chance of a short occurring from a bent spring or an over-tightened atomizer before using them will all serve you well and further your chances of remaining incident free. pcb protection circuitry takes a few of those concerns out of the equation, well at least lessens them somewhat, but careful use rules the day with each and every one of these cells.

now back to the LiMN, which again i think is a great chemistry and is my go to in all sizes below 17670. but because the AW protected 17670, 18500, and 18650 cells offer vastly improved runtimes along with quality protective circuitry up to 5A to prevent over-discharge in the event of overuse or a short, and have continuous drain rates (3A up to 5.8A) capable of safely accommodating the demands of any atomizer we currently use, this for me is the right cell for the right application at the right time. the IMR18650 is a great cell for certain high drain applications, but it is overkill for vaping purposes, and really you're getting anywhere from half to a 1/3 of the runtime of the protected AW18650 cell. my thinking is if you are going to use a cell that big to begin with, then don't sell yourself short by getting the runtime of a smaller cell...at least not when the primary reason for using those cells is negated or rendered void by the protection circuitry of other cells, and the careful use and understanding of the applications you are involving those cells in to begin with.

it's a personal choice, and again, there is no such thing as a safe battery, just safer, and safer at different times and for different reasons. if your goal is simply to not have a battery that could explode in flames, don't use the LiCo cells at all. but if you feel confident you can use them properly, charge them properly, and put them in applications that don't place exceeding demands upon them and don't risk direct shorts due to user error, then you may feel, like i do, that the added runtime is well worth it, and your cautious and careful use along with protective circuitry already in place, will provide you with great peace of mind as well.
