    at what price?
    i am new to BUYING 18650 in the past few years i have been happy with pulled laptop cells
    but as i go further down the rabbit hole i splurged and bought many NCR18650BF 3400mAh 6A cells for~$3.85 non protected and i love getting 2x the run time as some of my older 2200-2600mAh pulls

    am i missing something other then ~100mAh (in my normal -4A needs) that the GA offer for 2x the PRI$E so far no LE$$ then $6 each non protected

    in the non protected format what is the allure of the ~$6 GA over the ~$3.85 BF for lower Amp usage

    Where you getting them for $3.85? AliBaba, FastTech, or some place like that?

    They're a good battery no doubt, but they seem to be drying up and not easily found at the more local places.

    i have 2 successful Ali E. orders and they both have been tested by me with my Lii-500 charger and are REAL
    the NCR18650BF $3.86 for 20pcs http://www.aliexpress.com/item/20pcs...74_75,201560_1

    the NCR18650GA $6.02 for 20pcs http://www.aliexpress.com/item/New-2...74_75,201560_1

    both are cheaper with the Ali App
    and i in know way represent any of these stores (i stand for the truth low prices)

    PS i do not understand why people buy the Panasonic NCR18650B over the the BETTER Sanyo NCR18650BF

    No real mystery...not everyone knows about every cell out there. The NCR18650B has a long and very positive track record going for it also. I have no doubt that the BF is just as good, but there is a lot less evidence at the present time.

    I agree with markr6...given the reasonable cost, excellent performance, and all-rounder capability of the NCR18650GA, right now that is my go-to cell. If you have a very specific application, it might not be the absolute best cell, but it is going to be very close, and for most of us, you cannot do better. That works for me...KISS is a good guide.

    finally got my first pair of Keeppower NCR18650GA's. One is in my new 4 amp Armytek Limited Edition Predator Pro V3 XP-L HI and the other is in my MH20. They took several hours to charge from the 3.7 volts I received them at which I found unusual. They took longer than even my 3600mah cells. I am in no way a battery expert so I do not know why they took so long to charge. So far so very good with these two cells! Both lights crank to the max and the 3500mah cells dont seem to drain as fast as any of my other cells. I am very pleased. Enough so I just ordered a half a dozen more Keeppower NCR18650GA's to spread across the vast mix of cells I have going on. Am using a VC4 charger with the upgrade wal wart USB charger for the iPhone 6 I am probably wrong but I think the wal wart is 5 amps? I just know that with the VC4 plugged into this thing it never drops below half an amp even if I am charging 4 of my stoutest cells all at once in it.

    Just curious, did you get the protected version?

    Just scored 6 of these. $2.70 each!!! They're flat tops, so they'll only work in a few of my lights. Didn't need them, but I couldn't pass that price up!
    GOOD TINT!

    Nice score!

    I must say, if a n00b with 3 posts and an xxxx-Fire signed up to tell us about this price, I would be asking whether it sounded too good to be true. In your case, however, I know you are careful, so I am covetous rather than concerned!

    HAHA I agree! One thing I never liked about these cells are the wrappers. They just feel and look cheap like the laptop pulls I've seen. In the past I have been purchasing from mtn electronics with a button top because I like the shiny wrapper and the extra thickness reduces rattle. The problem is, 3 out of 4 are TOO thick for some of my Zebralights.

    I ordered some clear wrappers from Illumn to put on these new ones just because I am that anal retentive

    It was a black friday deal from an ebay seller. Unfortunately no more deals like that in sight.

    Any updates on these batts? I'm looking for 20-60 of the ncr18650ga cells for an Rc project. I've heard of people finding them for around $4 each but I can only find much higher prices.

    I've used FastTech a few times with good results.

    $22 for 4 of them:

    The charge rate on this cell is ~1.5A, which is about 0.4C. My charger only charges at 1C, which is 3500mA in this case. Will I damage the cell?

    I just saw some KeepPower protected 18650 3500 mAh cells on Amazon that appear to be the NCR18650GA. They're a 2-pack for $17.99 with plastic case. Are these preferred over the Panasonic 3400 mAh NCR1865B cells that I currently use? I'm looking for stronger cells for a TM26 and am wondering if these KeepPower 3500 mAh are worth upgrading to. TIA.

    Depends on what discharge rate you need. The Nickel Cobalt (NCR) electrode is the most durable one out there. The most proven technology but rated for a lower output. Keep in mind: the higher the energy the higher the amp rating the lower the ultimate service life.

    Sanyo GA is an NCA chemistry cell. it's basically a tweaked panasonic NCR in sanyo packaging (sanyo and pana now 1 company)

    yes NCA chemistry has very good CALENDAR life if that's what you mean by "durability". but has less cycle life than some NMC chemistry cells

    NCR-GA beats NCR-B in capacity, energy, voltage sag so yes get the GA unless you could buy the B for super cheap

    What charger only charges at 1C?

    Sanyo NCR18650GA dents easily, at least at positive tip. I have two, they were used in my Convoy S2 flashlights, both Nichia 219C and NVSU233A-U365, and the batteries got dented at the positive tip, from even the minor drop. Looks like I will have to replace the springs with somewhat softer one like the one in Convoy M1 flashlight (this one never dented the battery - LG INR18650MJ1 which I will just permanently pair with, so I wonder why). I am not saying it's a bad battery, but it's that the GA cells seem to have weaker positive cap for some reasons. So, if you have tighter flashlight configuration, beware.

    1.When I buy from titan battery.com,, the battery have "C" mark,, but when I buy at Local store The Mark is "B",,

    2.I Set with NIMH operation at the charger,, discharge set to 2amp
    When The Charger begin, it show discharge at 1.4 amp,, the voltage drop from 4.2 to 3.86 Volt ,, this is normal?
    I have no graphic,, I try with note,,
    >when the voltage at 3.4 Volt,, the "Mah" that I got is about 1100 Mah..
    >when the voltage at 3.0 Volt,, the "Mah" that I got is about 2300 Mah..
    >when the voltage at 2.8 Volt,, the "Mah" that I got is about 3205 Mah..
    everything is normal?

    I did not try The "C" Mark Yet


    Discharge with SKYRC balance charger,, 2 amp discharge,, until 2.8 Volt,, I got about 3205 mah

    thank YOU,, I upload the Picture
