I used the SLS database. For the LG cells I added both part numbers to the database that way if you have one that has the "LG" prefix it is there or if you have the ones with the "ICR, INR" part number they are therealso.
Sure, but there are long strings of letters and numbers after it on LG cells which I can't determine if they will mean anything to me or anyone else down the line.
The most important numbers are the LG and ICR/INR. Don't have any ICR or INR pictures but you get the point.
The rest of the strings are production date and possibly time, lot number, plant number, etc.
To decode that you probably need a Turingmachine to crack the Enigma codeor there may be a cipherer key somewhere.

3 seperate storage areas. < 1.5V are IR checked and if there is any IR the cell will be matched with other similar low voltage cells and slow charged at 50mA in a 20p CC/CV assembly.
What did you use for said assembly? I have ordered 6 four-bay TP4056 chargers and plan to modify them with lower current and possibly a bleeder resistor if the TP4056 does not play ball at 0 V. Datasheet is ill-defined here.
Ah yes actually quite a simple assembly.
5 - 4 cell 18650 holders on a piece of lexan 2 bus bars with banana plugs on the ends.Solder the holder terminals to the buss bar. Ifused the neg side with small wire(already had to replace 3 can't seem to tell neg from pos sometimes :dodgy: ) a small V meter for eye candy.
A CC/CV Buck to adjust V and A with output to banana plugsthat's it.
The Fluke is there to show me the microvolts as the batteries climb in V. Kinda neat to see it climb very gradually and then stall. You would never catch iton a 2 decimal meter as the the tenth, andhundredth don't move. You might catch it on a 3 decimal meter but not as quickly.
Once it stalls I take all the batteries out and check the V and invertanly 1 or 2 will have very low V and the other ones will show the V that was on the Fluke. I also have a thermal imaging camera that will show a warmer cell that you can't even feel with your hand. Just to think charging at 50mA per cell and there are the heaters in plain sight well to the infraredeye anyway. You see the ambient temp is 19.7C and the Battery is 23.0C barely can tell by hand. The other 3 cells on this particular CC/CV board show cool.
That's it.
