When load testing, charging and discharging them a few times does up their mah at bit and they hold just a bit higher voltage. It's pretty miniscule, but it is observable in the graphing.

I ran into some problems getting these down, they are flat on both ends and I am missing my magnets, some i'm having a hell of a time getting good contact on my test fixture. I Just want you to know I haven't forgot and will get these done as soon as possible.
I add solder to the pos terminals of my flat top. If you're comfortable doing it AND it would allow it to connect to your test rig, feel free to do it. It's going to happen to them anyway.
FYI... Solder paste works better than wire solder.

I dont have the equipment to test, but these Sony's ROCK!!!!!
They have handled anything I have thrown at them........
They have handled anything I have thrown at them........
The way I look at it is.............If it aint broke dont fix it, AW's have a Proven track record.... Why buy another brand that "might" be as good but needs solder applied to the positive terminal ???

The way I look at it... If you don't branch out and try new things, you'll never find anything better.
The most dangerous phrase in the language is, "We've always done it this way." ~ Rear Admiral Grace Murray Hopper
I agree with you on tring new things...........
So may I ask you have you found anything better? Im runnung a pair of AW 18650 IMR 2000 mah batteries that have been used evey day for the past 14 months......... They still hold charge full day plus of vaping......
I havent seen any new miracle battery chemistry with leaps in mah rattings yet......

Think about it in this light, technology improves over time, those AW's were brand new products on the market at one point, and some people were saying to stay away from them back then.
These Sony's rock, so do the new Panasonic PD's. Next month there will be something else out thats new and potentially better. One day those AW's will be very old school.
Some folks like cutting edge, some folks like tried and true, whatever floats your vape.......
When cutting edge is leaps and bounds ahead....Im in...... Otherwise its the slow trickle of new technology that we are forced to buy... I want the stuff thats already developed but wont be released until 7 years from now..... Manufactures have to much R/D money tied up in the outdated stuff their selling now to give us whats really "cutting edge" !

Yea... There plenty of batteries that have been shown to be superior the AW 2000 mAh battery... The AW 1600 mAh being just one of them... Matter of fact, it's been pretty clearly demonstrated that a battery's max discharge rate is a better indicator of performance in a mech device than its capacity (mAh). The reason being that the higher the discharge rating, the better it's ability to deliver and maintain a higher voltage under load. The difference becomes more pronounced as the amp load is increased... That is to say, the lower the resistance of your coils, the more evident the difference.
When you look at the charts below, keep in mind that we can consider a battery "dead" somewhere between 3.7 and 3.5 volts. Vaping a mech at voltages below those voltages is anemic at best... So, any capacity that is shown below the 3.5 volt line is wasted.
As you can see, @ 2 amps the AW 1600 mAh and AW 2000 mAh are pretty much equal. When you compare them @ 5 amps, however, the 1600 mAh version is shown to be clearly superior.
And out performing both of the AW batteries, at all tested amp levels, is the Samsung INR18650-20R...
These graphs were created here... http://lygte-info.dk/review/batteries2012/Common18650comparator.php
Unfortunately, the site has no info regarding the MNKE batteries or the Sony batteries... Thus my reason for sending the two batteries to David for testing.
Let me start by saying this... Soldering batteries can be dangerous, both to the battery and your person. Soldering lithium batteries can be VERY dangerous to both the battery and your person. If you have no experience soldering batteries, PLEASE DO NOT attempt to learn using lithium batteries!
With that said and out of the way... With the right tools, supplies, and knowledge, it can be done quite easily with little to no risk of damaging either yourself or the battery. Fortunately, I have all three, so I see no need to skip out on a great battery simply because it's nippleless.
Also... There's no need apply solder, magnets or anything else to a flat top battery if you're using it in a Super-T devise. The only reason I do it is because I also want to use them in my ProVari. My XTAR charger doesn't like flat tops either but that's easily remedied with a small M3 screw.
Heres the Samsung INR 18650-20r VS the AW IMR 18650 1600mAh at 5amps continuous load. At its best it holds 7/100 hundredths of a volt higher and at the least, 2/100 of a volt higher. Low enough voltage you probably wouldn't notice it vapor wise(especially since the test is at 5amps, so the voltage spread would be less at lower amps), but you would gain a bit in life if you change out batteries by 3.4 volts on a mechanical mod (see below).
Break down:
Samsung INR 18650, Recorded mAh at 3.4 Volts: 1368 mAh
AW IMR 18650 1600mah, Recorded mAh at 3.4 Volts: 1211

Thanks David! Looks good. AW is certainly no slouch. The fact that the Samsung beat it, even if by a narrow margin, shows that it's a good battery. Now only time will tell if it's able keep it up after N number of charging cycles.
So why don't I hear mention of those Orbtronic Panny's that Bishopheals was talking about?
Did they end up being junk?
Did they end up being junk?
They're test results can be found here... Battery test-review 18650 comparator
I wouldn't call them junk but I don't think they're as good under load as the ones we're talking about here.
The 2900 Orbtronics in the Comparator are not the hybrid 2900 Panny's, they are ?
The 2250 hybrids are there a couple places, Efest 2250, Orbtronic 2250, they do pretty well but not after figuring in the cost
