ok …… I wish I could get them at that price as their $12 on average here .
Panasonic owns sanyo, each cell has its own name. Panasonic’s 3400 cell is the NCR only good for around 6 amps. But sags heavily after 4 amps. The sanyos 3400-3500 cell is the sanyo GA. 10 amp rated cell. Its developed by sanyo, sanyo never recovered from a major earthquake and Panasonic owns it now. Might not see to many new cells with a sanyo label on it. Essentially they are the same company now. All the high drains are comparable. Sanyo/lg/Samsung 10amps you couldn’t tell a difference in the 3 lights you have. And the 20+amp cells are all similar. 30q/HG2/VTC6/ etc
You won’t go wrong with Panasonic or sanyo cells. I recommebrd the sanyo cells since they are the same price as the Panasonic outdated NCR B cells. And said if you ever get more powerful lights that draw over 3 amps you already have cells now for it. Panasonic makes good cells all the big manufacters do. Sanyos plant was hit during a massive quake. And just never recovered fiancialy completely. Panasonic bought them out to get their battery formulas and technology. They let sanyo keep operating with its name for the time being but that may change in the future.
Like Walmart and samsclub two different companies but both owned by walmart
To the OP I have 3 of these lights & for the money they are great little lights :+1:
I tested the claimed 3000mah “crapfire” cells that came with them & got 600-800mah iirc & very high resistances & after charging voltage dropped like a stone 
They are very very poor cells.
I recycled mine.
thanks all .
and thanks Speed4goal that sounds about right for these days so I will use what I have coming
and will get more for my c8 and 2 olight M3X and it looks like I will get another 2 or 3 c8 for
the money they are a great light + I ordered an OP reflector for around the house and yard .
cheers D
Yes! :+1:
well this is getting interesting ……… I ran one of these cells down to 3 volts and then put it in
the charger and after 15mins it was at 74% so I thing this is one of them 3000mah cells that
hold 300mah haha .
EDIT charge rate is 1A
EDIT 2 it took 1 1/2 hours to charge so about 1100 to 1200 mah
ok I was doing some research on batteries and because the ones I have coming are SANYO
NCR I found this …… the chemistry of the NCR is LiNiCoAlO2 so the question is can I charge
these on my XTAR SV2 Rocket charger as this is all that is listed Li-ion/IMR/INR/ICR not the
NCR cells .
cheers D
Yes charge away. Any 3.6/3.7 lithium cell is fine. They charge up to 4.2 volt. Cells are rated by nominal voltage.
I see one of the “tips” in the SV2 Rocket manual is to manually reduce the charge rate from 2A to 0.50A when the battery is “almost full”. I suppose this gives a more accurate termination point?
hmmm now where is my manual

“An example that you can observe yourself – take a look at the button top on your cell, do you see any vent holes?”
Is this the vent holes you’re asking about…? There are 2 of them on opposite sides.
um I found it but it ain’t no good to me as it’s all in Chinese :rage:
Reading the translation is half the fun of getting new Chinese product! The instructions don’t say you have to reduce the charge rate, it is automatic, but reducing it is a “tip”. Otherwise the instructions seem common to other charging practices. I’m pretty new to this and needed a faster charger for the 26650s in a couple of new lights I bought and I found the SV2 on sale. :money_mouth_face:
I figured there was something going any was as it gets to 99% and then takes ages to finish
They’re all the same, made in the same factory. Sanyo has been a subsidiary of Panasonic since 2009. Sometimes they put Panasonic logo on the product and sometimes they put Sanyo logo, but it’s essentially the same product beneath the label.
:+1: Those are the ones! It doesn’t mean that the cell has internal protection, but a lack of them would indicate that it does not.
If you are using these in a light that draws 3 amps or more, you will certainly benefit from a better cell such as panasonic sanyo samsung sony lg.
Better meaning higher voltage under load, higher capacity, higher amp capability, lower internal resistance, resulting in more lumens.
SANYO NCR18650GA 3.7V 3500mAh ……….?
ok my sanyo cells rolled up today and I must say they look very plane jane
now I know this don’t mean much but all the have is a white sticker on them
and one of them small square things that you read with your phone .
so does this sound right or are they knock offs .
cheers D
Where are you buying batteries from deye?
these two sellers …… on the sanyo add you can see the QR code on the cell
