    .






    I found these with the best {low impedance / resistance} protection IC curcuit. [Well that's what's claimed, & seems to be true]

    3. Protection Circuit Electric Characteristics (Ta=25
    )
    3.1 Overcharge detection voltage(VCU): 4.275±0.05V
    3.2 Overcharge detection delay time: 1.0±0.5 S
    3.3 Overcharge release voltage: 4.075±0.05V
    3.4 Under-discharge detection voltage(VDD): 2.5±0.10V (Reducing with higher loads)
    3.5 Under-discharge detection delay time: 1.0±0.5 S
    3.6 Under-discharge release voltage: > 2.9±0.1V
    3.7 Excess current threshold (IEC): 12.5A
    3.8 Maximum Continuous Current 9A
    3.9 Short detection delay time: MAX.18mS
    3.10 Supply current (V cell=3.5V) : MAX.10μA
    3.11 Standby current(V cell=1.8v) : MAX. 1uA
    3.12 PCB total resistance: MAX. 30mΩ. (we tested 12 mΩ)
    __________________________________________________ ________________________________
    Typical dimensions with protection circuit are
    Height: 68.8 +/- 0.05 mm
    Width: 18.65 +/- 0.05 mm
    Battery Impedance with protection circuit (milli-Ohms 1000Hz) : < 35
    Nominal Voltage : 3.6V
    Nominal Capacity: 3450mAh (typ.)
    Standard Charge current : 1475mA
    Max Charge Voltage (CC/CV): 4.20V
    Min Discharge Voltage: 2.5V
    Max Cont. Discharge Current: 9 A, limited by PCM
    Weight: 47.5g
    Note: The added protection circuit and nipple top adds a considerable amount of size to the battery. If your device is a tight fit with a bare cell, chances are the Blazars will be too large.


    Has anyone heard of Blazer?
    ...Meant to be similar to Keeppower cells.

    As a marketing professional, I won't use a cell with Comic Sans (or variation of it) on the wrapper! Just kidding...but not really
    GOOD TINT!

    i did some google research, found the cell at nice price on NKON.nl site, they also posted the datasheet PDF

    http://eu.nkon.nl/sk/k/ncr18650ga.pdf

    cheers!

    As i understand the PDF correctly, the EOL is reached after 300 cycles. Not bad.

    i seem to have found the NCR18650GA BLACK (w/PROTECTION) for about $8
    http://www.aliexpress.com/item/NEW-N...390256552.html

    and the NCR18650GA RED (non Protected) are pennies LE$$

    but what intrigues me is the price of the NCR18650BF now at ~$4
    WOW!!! how can that be the NCR18650BF & NCR18650B have REIGNED AS KING for 3 LONG YEARS
    and now with the LG and Pan 3500mAh just out the proven 3400mAh drop to about 1/2 their price from just 2 months ago

    can someone school me as to what is going on

    thank you

    Simple supply and demand. People want the newest and best, and are generally willing to pay for it. So when the NCR18650GA came out, it became the new 'top dog'. And the NCR18650B became the 'has been'. Thus, its price went down.

    Old tech usually does drop rapidly in price when new tech comes out. It was surprising to me as well to find the NCR18650GA was actually cheaper than expected...the 3600 mAh NCR18650G was much more expensive, and harder to find. The competition has recently gotten a lot more intense...LG is selling some excellent cells now too, whereas before it seemed like Panasonic had almost a monopoly, at least for the highest capacity cells. So it isn't TOO surprising that prices are dropping.

    I wouldn't go anywhere near that Alibaba link, though. No brand specified...that is a major red flag for me. It MIGHT be a good cell, but I simply don't trust generic cells. In the USA, Mountain Electronics has the NCR18650GA for a good price, and I know I can trust that those cells are genuine, and will deliver the rated performance. Not so with Alibaba...there is a reason they are cheaper.

    The 4 I recently got measure around 85 milliohms. My Opus charger is definitely not the best for measuring this, though. But in comparison quite a bit higher than my Samsung 25R cells around 45.
    GOOD TINT!

    From what I have been researching, these cells are the core of the new EagleTac 3500's http://www.ledfiretorches.co.uk/eagl...ithium-battery

    Here is some info I put in a notepad from some other site:

    IC PROTECTED Rechargeable Cell
    (takes the place of 2-123 cells in some applications)
    (4.2V hot off charger)
    Features:
    - Uses newest Sanyo 3500mAh Li-ion/NCR18650GA Cell, Made in Japan.
    - This is the shortest ultra high capacity 18650 ever made WITH TRUE Button top!
    - Measures only 68.1mm in height (+/-0.1mm) and 18.2mm in width.
    - IC protected for a) over-charge, b) over-discharge, c) short circuit, d) current overflow of 12A+
    - True protrude/BUTTON top design, fits/functions all flashlights.
    - High Discharge Rate 10A+
    - Nominal Voltage: 3.6V, charge up to 4.2V, use CC/CV charger to charge.
    - Thick Black Wrapper, Reinforced Steel Plate Bottom, highly efficient protective PCB design.
    - Packaged in individual box and anti-static bag.
    I have a couple on order, hoping to get them tomorrow. I have not seen any hard reviews on them yet, but from all accounts they are a great battery. I'm all up for sopme 3500's I do not know if the size benefits are only on the eagletacs or if they are on the base Sanyo battery. It is like pulling teeth trying to get info on these cells.

    On paper, the protected NCR18650GA from Mountain Electronics looks like a perfect match for your Fenix PD35. I say "on paper" only because I do not own either! I have, however, already selected that battery for my next protected 18650 purchase.

    my NCR18650GA cells (4pcs) arrived today from akkuteile.de, original voltage was 4*3.66V date code 2015.03.18.

    Only reason I didn't get the TAC model is because I did a quick search and found the 2014 edition for $56 and just went for it. Normally I would be regretting not having the latest and greatest, but my hope is that I'll be perfectly happy with the one that arrives today (the 2014).

    Per a reply from Mountain Electronics that I got to an email, regarding the use of the NCR18650GA in a Fenix PD35 ... "The Protected GA is an excellent battery for a light like that, as long as it fits. The GA has a much lower internal resistance than the B, so it will maintain peak output for longer than the 3400mAh NCR18650B."

    I've two of the 2014 PD35, they're not going anywhere out of my possession or family.
    Even if/when I upgrade, they'll still be kicking greatly.

    Here is an informative comparison, at 1A, 3A, 5A, 7A, and 10A, of the 18650GA versus the Samsung 18650-35E and LG 18650-MJ1:

    I have my first pair of these NCR18650GA's being delivered to me tomorrow in the Keeppower flavor and am looking forward to it. One cell is destined for my MH20 the other for the Predator Pro V3 XP-L HI that shows up early next week. I will be comparing and contrasting out put and run times across the 2 new GA's, the 12 3600mah Orbtronic 18650's I have and finally against Orbtronic 3400mah cells and Keeppower 3400mah cells. Should be interesting. From what I have read these new 3500 GA's hold roughly 50-96mah more per cell vs 3400mah and because of the lower IR support max output much better? Cannot help but be afraid one of these new 3500mah 10amp capable cells may blow an emitter but according to Orbtronic they are specifically designed for flashlights?

    I wouldn't worry about that. You could put a 30A cell in there and it would work just fine. I believe the electonics/emitter will take only what they need to run...high drain cells may produce more output but nothing earth shattering. Someone correct me if I'm wrong.

    Unless you're frequently draining cells down to 3.0v or so, I think you're just wasting money and actually sacrificing brighter-for-longer output with some of the high-capacity cells.
    GOOD TINT!

    I ordered one NCR18650GA with the EVVA label from Mtn Electrics specifically for my MH20. It arrived with a charge of 3.79 volts and I promptly charged it up to 4.2 on my Nitecore d2 and it now resides in my flash light. Haven't really used it a lot as it stays in the console of my truck so I'll be interested in reading your results when you get yours. My understanding too was that these batteries are designed for the high power flash lights so I'd think the MH 20 would be perfect for it. I'll probably order more later on, for some reason I like the EVVA bats and at $10 ea at Mtn Elect. it's pretty reasonable and he ships pretty quickly. My battery/light budget for this month is getting a little low though. I just wanted to have the best battery in my best light. When I get more the next one will probably go in my Sunwayman P25C.

    I work 2 jobs one of which is part time night security I am outside in the dark a LOT for hours on end so yes even my stoutest 18650's get run pretty low by the end of a shift. I rotate through my dozens of lights but the most common ones I use at work are the compact 18650 lights like the MH20 and ZL SC600 MkII L2. I frequently can run these lights from freshly charged at the beginning of a shift to as low as 2.6/7 volts by the end. It is not uncommon for me to go to work with 4-6 flashlights on me along with my baton etc. I have a LOT of ground to work foot patrol and being able to pull a long, medium or short range light at a whim is a huge advantage. Sounds like these GA's should really rock! What ever happened to the Orbtronic/Keeppower 3600mah cells?

  28. #58

    Default Re: Sanyo NCR18650GA 3.6V (3500mAh, max. 10A)

    From HKJ's 18650 comparator:



    Enjoy the GA's! At 2 amps, the Keeppower 3500 (likely NCR18650GA), does better than the Orbtronic 3600 (NCR18650G) until about 3.15v. That's pretty low and you would have to drain the battery past that to realize any benefit. Even then, they're pretty close and the total runtimes are within a couple MINUTES (at best). Useless in my opinion to spend an extra $10-15 per cell!!!

    At 5 amps, the 3500mAh actually does better for the entire curve. Brighter flashlight, longer.

    I really think the NCR18650GA is THE cell to buy, with the exception of some crazy-high applications like vapers or highly modded lights. And maybe a few stock lights like the Noctigon M43 to realize the maximum output.

    Even if you buy 18650GA for EVERYTHING, and you're not even using close the 10A drain capability, you're not losing anything considering they cost about $9 each.

    I pretend to know what I'm talking about, and I like to think I understand this stuff. If I'm wrong, someone politely correct me
    GOOD TINT!

    In a direct comparison of the NCR18650GA and the Samsung 25R in my S3 EDC driven at 4.4A, the 25R put out no more output than the GA. This was true also in my M2Xvn driven at maybe 5A at best. So I've basically got a couple 25Rs sitting around now that will collect dust. I believe the GA in the protected flavor is the way to go for everything now.
