Cell Database Submissions and Updates
#51

 
 

Just got over a cell that seems to miss in the database.


I found a webpage with specs here: https://www.dnatechindia.com/LG-MJ1-1865...india.html

  • Nominal Voltage: 3.635 Volts
  • Nominal capacity: 3500 mAh
  • Minimum capacity: 3400 mAh
  • Max. Charge Voltage: 4.2 ± 0.05 Volts
  • Max. Charge Current: 1.0 C (3400mA)
  • Max. Discharge Current: 10 Ampere
  • Weight: 49.0 Grams
  • Operating Temperature Charging: 0 ~ 45°C
  • Operating Temperature Discharging: -20 ~ 60°C

EDIT:
Found a Datasheet here: https://www.nkon.nl/sk/k/Specification%2...8.2014.pdf

EDIT 2: 
Possibly the same as LGDBMJ11865:

It is self explanatory as far as mAh is concerned but no other specs.
on the SkyRC M3000 the are showing ~2150mAh so not a bad cell.

Hey, I found one of the same brand/logo, different number of sides on the top cap, no discernible model number (no luck on finding data either):




And here's a Samsung ICR18650-24B, which appears to be a variant of the 24A/24E that are already in the database. No datasheet that I could find, but there's data on it at Voltaplex and here: https://voltaplex.com/samsung-24b-18650-...r18650-24b https://merkandi.us/archive/battery-li-i...mah/256007 which claims 2400mAH capacity, 3.7V, 800mA standard charge, 960mA "rapid charge", 2.4A max charge, 4.8A max discharge.

This is likely a Sanyo UR18650A: https://secondlifestorage.com/t-Sanyo-UR...ifications check the side for a faint imprinted model number.

Specs are available on the website: http://www.efestpower.com/index.php?ac=a...ad&did=396

Model: IMR18650

Rated capacity: 3000mAh
Nominal Voltage: 3.7V
Voltage cut-off: 2.5V
Max Charging Current: 4A
Standard Charge: 2A
Discharging Current: 20A
Plus Discharging Current (their words not mine): 35A
Charging Temperature Range: 0 - 45C
Discharging Temperature Range: -20 – 75C

Vape cells like this are usually rewraps of major manufacturer cells. This one for example looks very similar to an LG HG2 (same top cap shape/sides, very similar voltage curve shape:

First time I'm meeting up with these prismatic cells. Body is negative, just like on 18650s.
MOLI ICP1003540B from MOLICEL Canada. 3.7V, 1800mAh typical.

Link to the specsheet, seems legit: https://download.siliconexpert.com/pdfs/...-82019.pdf

Generic 2AH cell to add, closest I can find on spec/appearance is the following cell from Greenway battery:
https://www.globalsources.com/gsol/I/Lit...1169141944 https://www.alibaba.com/product-detail/d...72f753Wbmj https://www.greenway-battery.com/product...ll-30.html
18650E-0200 Spec states 2.2AH typical capacity, 4.4A max discharge rate.





And here's a generic 3200mAH cell I bought from eBay. Thought it would be fake but turns out to be real (or at least close to spec, 2963mAH tested in a Miboxer C2 4000 at 1.5A):

 
 


Again hard to find sources but I believe it is a DLG cell, INR18650-320: https://www.alibaba.com/product-detail/1...6806abg0h7 https://www.alibaba.com/product-detail/W...6806abg0h7 https://www.alibaba.com/product-detail/H...6806abg0h7
Spec states 3.1AH minimum, 3.2AH typical, 3.2A max charge current, 6.4A max discharge current (to 2.5V), <40mOhms IR.

Update, got a datasheet for the INR18650-320 from DLG. 1C charge, 2C discharge max.

Found some LG cells that don't appear in the database. LGABD21865. Found in two Dell 65 Wh laptop packs (P/N 04KFGD). All tested right around 3000 mAh and around 50 milliohms.
