Samsung INR18650-35E 3500mAh (Pink)







Official specifications:

  • Nominal capacity: 3500mAh

  • Minimum capacity: 3350mAh

  • Nominal voltage: 3,6V - 3,7V

  • Charging voltage: 4,2V

  • Discharge current: 8A

  • Maximum discharge current: 13A

  • Charge current: 0,6C 2000mA

  • Discharge end voltage: 2,65V

  • Pluspol: FlatTop

  • Chemistry: LiNiCoAlO2

  • Diameter: 18,55mm ± 0,1

  • Height: 65,25mm ± 0,15

  • Weight: 48g ± 1




This is one of the new high capacity cells.










The discharge curves has good tracking.
At 15A the B track stops just after 2.3Ah, this is because my battery holder melts (I hope this is fixed now).







15A is definitly too high current for this cell. The cell temperature is above 75°C (25°C ambient + 50°C temperature raise). Logfile says 87°C for A cell.





On this chart it is obvious how the heat improves the performance at 15A.







Due to the melted battery holder I did only do this for one cell.





Conclusion

The cell looks very good, it has lot of capacity and can handle some current, but I will not recommend it above 10A.

Thanks for the review

You write:
“On this chart it is obvious how the heat improves the performance at 15A.”

You mean “is rising” or “is going up” instead of improves right?
Or are those bump in the charts actual improved preformance linked to heat?

3

The bumps are improved performance due to heat, the chemical reactions goes faster when the cell is hot (This do also wear the cell down faster).

4

Thanks for the review HKJ.
Seems like the latest high capacity cells, like this one, Sanyo GA and LG MJ1 are good for up to 10A

5

AFAIK the 35E are rated for 8A continuous. I stopped testing at 10A. Driving them to 15A is just battery (and cell holder) torturing - for the sake of science :wink:

6

Thanks for testing !

7

Been waiting for this one for a while. Now all we need are the 30Q, GA, HG2, and MJ1.

8

Thanks very much for the test! I will put these in a power bank, according to the chart they are superior to the GA in all low discharge rates. But they seem to be out of stock everywhere?

I’m 90% sure HKJ has already tested the 30Q, GA, MJ1 and HG2, but in rewrapped versions.

This IS the GA
http://lygte-info.dk/review/batteries2012/Evva%2018650%203500mAh%20(Black)%20UK.html
I assume this is the 30Q
http://lygte-info.dk/review/batteries2012/Imren%20IMR18650%203000mAh%20(Yellow)%20UK.html
I assume this is the HG2
http://lygte-info.dk/review/batteries2012/Efest%20IMR18650%203000mAh%20(Purple)%202016%20UK.html
I think this is the MJ1
http://lygte-info.dk/review/batteries2012/Imren%20IMR18650%203500mAh%20(Green)%20UK.html

Althought, the curves for the Imren green and EVVA black are identical up to 5A, but the imren green top doesn’t match the GA 3-leg raised top.

9

Thanks for another supremely useful test.

10

Thanks, but the link you posted for HG2 seems to be wrong. The Imren 3500mah does not look like the MJ1 at all to me.

11

Oops sorry, I meant to link this one
http://lygte-info.dk/review/batteries2012/Efest%20IMR18650%203000mAh%20%28Purple%29%202016%20UK.html

It's been said by many here that this the HG2, the performance at 5A+ is sightly better than the 30Q.

I researched the web and could confirm/partially confirm two of your assumptions.

Confirmed: Sanyo NCR18650GA 3500mAh = EVVA 18650 3500mAh (Black). [Reference RMM]

No information found: Imren IMR18650 3000mAh (Yellow) ~ Sanyo INR18650-30Q 3000mAh.

No information found: Efest IMR18650 3000mAh (Purple) ~ LG INR18650-HG2 3000mAh.

Note: The Efest IMR18650 3000mAh (Purple) may or may not be Samsung INR18650-30Q 3000mah. [Reference Mooch]
Mooch is the resident battery expert at E-Cigarette Forums, like HKJ is our expert. He says that there are multiple versions of the purple Efest cell. The three-pronged positive terminal version is probably a 30Q. He hasn’t tested the 4-pronged version. The picture of the one HKJ tested shows 4 prongs. So, my interpretation of this is that “maybe it is, maybe it isn’t” a 30Q.

Yes and No: Imren IMR18650 3500mAh (Green) = LG MJ1 18650 3500mAh. [Reference Mooch]
Note: Mooch states that there are two versions of the Imren battery. One is a Panasonic NCR18650GA 3300mAh, the other is an LG MJ1 3500mAh.

Unless there is further documentation, I’d suggest that HKJ has not already tested the 30Q or HG2 batteries in any form.

What do you say, HKJ? O:-)

13

You could just look at my reviews of the mentioned cells posted here on BLF. The discharge curves are as good as HKJ’s.

14

I often look for your charts here and on CPF but sometimes I can’t find a specific one that I’ve seen before, I think you could make index thread with all your reviewed batteries and put the link in your signature, that would be really helpful!

15

I hope you weren’t responding to me. I merely attempted to confirm what HKJ said (or implied) about the Sanyo NCR18650GA, Sanyo INR18650-30Q, LG INR18650-HG2, and the LG MJ1 18650 batteries. I was not looking for what other people’s tests had found regarding these batteries.

If you were responding to Bugsy’s post #7, I found your tests of the GA, 30Q, and MJ1, as follows:

- Test/Review of Olight 18650 "3600mAh" protected (ORB-186P36) with NCR18650GA

Can you point me to your test results for the HG2?

16

Could be that I haven’t posted these on BLF. Way OT, but here are the HG2 vs 30Q discharge curves:

17

Thanks Light-wolff. :slight_smile:

You can also see discharge curves at 2A, 3A, and 5A for these 4 cells at ELFBAR VAPES ® | Starke Mengenrabatte | Alle Modelle

Anyone know where to get these 35E? I’ve been searching and everywhere is out of stock.

Banggood uses your graphs in their product description. Did they ask you? :open_mouth:
