New AW Cells

Kemosabe sir you forget the biggest bonus AW cells have had in the past over LG, Sony, and Samsung- longevity. My Sony VCT4's lost 20% of their capacity after only 231 and 233 charges. They were never ran lower than 3.61v, charged only at .5a on an xtar sp2 charger, never left to sit for more than 24 hours, etc. VCT5 were similar at 226 and 229. Samsung 25r I haven't personally tested but according to even their own tech sheet they should lose 50% capacity after 250 charges. Shortest lasting AW cell I ever had (with proper charging and handling) was 496 charges. Just trying out the new cells, but according to AW they should last >500 charges, and based upon past history will be shocked if they don't.

 

Before I'll go spending my money. I'll wait on some testing. I used to buy AW Rcr123's rated at 750 mah. Tests showed they're actually 500 mah. I went with Nitecore this time around.

 

Use a hobby charger Kemosabe sir. Sadly they're not very affordable, but do allow me to see how much amperage has gone into the battery. Can tell you in the early tests of 6 different AW 2200 AW cells the capacity were as follows-

1- 2212
2- 2205
3- 2208
4- 2204
5- 2210
6- 2207

Their internal resistance calculated at 0.05, same as that of the 1600mah AW cells. That's 0.04 lower than the 2000mah. Their voltage curve has been very impressive thus far, but won't be done with all the tests for a bit.

Always excellent to see you sir.

 

That is an impressive 18350, If I used them more often I would probably pick up a pair. There is currently only one higher drain IMR 18350 that I know of, the Tensai 14A which I believe is only 700mah.

 

Good information.

 

I have just bought couple pairs to replace my Panny PD. The consistency quality of AW is unbeatable.

 

Interesting ... the old 2000mah AW 18650 was a 10C battery. That makes it a 20A battery. Sounds like the 2200mah battery has a lower C rating.

 

To my knowledge the old AW 2000 mAh is a 10A battery.

 

Ryedan sir you are correct, AW imr 2000mah is 10a, not 10c. There is not an 18650 30amp cell on the market without active cooling (this goes for Sony as well).

 

What charger do you use? I would like to take a look at a new charger.

 

iCharger208B sir. It usually goes for between $140-150.

 

Thank you Sir.

 

No problem sir. Happy to be of help.

 

You are right. I did some Googling to check and I found where I picked that up in a conversation here on ECF and took it for fact without researching. A little fact checking in multiple places showed that It's 5C after all!

 

I've added (preliminary) results for the 3 new AW

IMR 18350-800
IMR 18490-1200
IMR 18650-2200

to my database here: AkkuDB

(Caveat: I only had a single cell per size to test and am waiting for additinal cells to get some more results)

 

I didn't realize until now that dampfakkus.de is your website sk4477. I've been using it for a while now for good battery information. Nice to see you posting here these days

 

It's wonderful to see someone so knowledgeable with batteries posting here, I hope you continue to do so SK4477 - Now getting right to the point, I know AW used be really good but honestly I expected better than those results, in my eyes that is pretty poor performance for a 2200mah battery at 20A.

And again the 12A 800mah 18350 shows poor high drain performance, the Tensai is destroying it!

Seems to me that AW is falling behind, I'm waiting eagerly to see some new test results on another batch of those cells!

 

New cell comparisons are revealing, I'd also like to see someone actually use the cells and retest at 6 months to see what happens with daily use. Lifespan of effective capacity would be a useful number.

I have 3 AW 18650 2000 MAH cells. One of those is 2 1/2 years old and the other two are about 6-7 months old. All three will give me about 4 to 5 hours of vaping at 7 watts. There's not much difference in the three in first vape voltage read by my Provari. All read about 3.9v using the Provari loaded reading and it doesn't matter whether I charge them on the i4 or the LUC 4.

My Efest and EH 2250 mah 18650's all read 4.1v loaded into the Provari and checked immediately. The Efests are also about 7 months old (the EH's are new) and I get an all day vape (12 hours or more) if I insert one around 7am.

All that is just anecdotal evidence, but I do wonder why batteries that have similar MAH ratings have much different discharge curves in actual use. What I'm seeing is more reflective of the discharge curves in these charts.
