18650 Cell obsession

Have I lost it?
MY favorite colors used to be red and blue now they have changed. Why I dont know but I have my suspicions. I think it has something to do with this 18650 obsession that has come over me in the last couple of months. I no longer look at red and blue as favorable colors they have changed and are now pink, peach, gray, green and purple. When I crack open a battery pack and there are purple, pink or green cells inside a big smile comes across my face that is noticeable to others. Not so happy with red.
I talk to myself saying to these inanimate objects that they are now free from their plastic prison and soon will be delivered and separated from their siblings to finally breathe on their own. Not that I treat the red or blue cells any different per say, it just isnt as joyous of an occasion when liberating them from their prison. On top of color am I becoming cell prejudice? I hope not as all of them get equal treatment up to this point. I dont measure voltages till all have been individualized and set free. Then I swipe them through my voltage reader and sort them out, again smiling at colors I never thought were very attractive, looking for telltale signs of high performance cells with 30A, 30B 29E on them. What is wrong with me?
Then the high performers go to the charging boards first and get a satisfying drink of electrons and hopefully dont overheat in the process as after fasting for so long and then getting a full meal can be detrimental to all of us. But then I think shouldnt the more hungry ones get preferred treatment as they are the ones closest to death? Oh oh there I go they are now my children and no longer inanimate objects. I talk to them I nurture them, I call them my spawn, my brood, and my children. I have not named them yet as some I have heard do with a barcode or some other means. That may happen if I continue with this psychoses. I get up at 5 in the morning to check up on them making sure they have had their electron nourishment and the green light is on. They then get set aside for a rest as others take their place at the feeding troth. This procedure is repeated as soon as I get home from work. My dog even looks at me rather strange lately as I keep bringing in self-gluing round circles and strips into the house on the bottom of my shoes. Also an occasional insulating circle will find its way to the paw and or butt of my pooch as he tours the shed where all the brood live.
Then I look to see how the previously nourished cells are performing.There seems to always be a similar pattern pink, purple gray and some greens seem to be the best at storing as many electrons as possible and releasing them in a controlled manner with a maximum result that make me smile. I then put them into a special place to be checked again for leakage in a couple of weeks or so. So far 255 of them have made the grade out of 600. I feel bad for the rest. What to do? They all tried just as hard as the others but where not chosen. Some of them due to getting too hot some of them for not releasing enough electrons some of them just because of their physical condition. How terrible if you are one of these cells never to play with any of their siblings again just to be stripped down for their remaining worth as raw material Death. Red and Blue are no longer my favorite color and I do believe I have lost it.

Has anyone else have this experience if so maybe we could start a self-help group Battery Addicts Anonymous (BAA)

Ive been having some great luck with Sanyo cells. But Ive not been getting the heaters as much <5% but I have benn getting lots of 2400-2600 ones :)
 
I can't say that I have had very bad luck with the Sanyo cells either but the percentage is definitely larger.
On your charging wall would you rather see this

Or This?

All that matters to me is the numbers when they are done ;) Processing cells may be the best part of the process but also so is looking back at your work when it's all done...... who am I kidding it's never done lol
 
This is on my setup right now

Nice I see you like to color coordinate also :)

It looks like you are charging in parallel are you finding an advantage to this?
Also you have 3 separate charging blocks are they for different voltages and amps?

I am experimenting with below 1 volt cells and get them up to 2 volts at 20 to 25 mA then up to 2.5 volts at 200 mA then to the tp4056 they go.
So far so good I have labeled them and they are sitting right now for a week and then see if they leak. Then to the Opus.
I'll let you know unless you have done this already and have some insight on this.

Noticed that Eh... lol Yea I cannot help it. I got a huge box of pre-processed cells that I'm pulling out of and they are all mixed. But I pick through to get a set of the same colour
