Good morning everyone,
When I was playing with my tester, i noticed that it is a bit of wasted time to test them first for remaining volt, then discharge to 3.9
To get them back up to 4.2v, to do a full range test, you just gain 25-50mah.
I have/had absolutely no experience with lio
Learning time is never a waste of time, imo.
I am someone that can read a lot, but i have to learn it by just to do it.
Just like what is a heater, you just have to encounter one.
I noticed that the cells that here being charged 3 - 4 weeks ago, i checked them on remaining voltige, there was almost no drop.
When discharge them to 3.9v to charge them up again to 4.2v you only gain ~25-50ma on the full range.
So when the voltage is still above 4.10v i just discharge, if a cell is between 4.00v and 4.10 volt i write it down on the cell.
Every cell below 4v will be set aside for a further test.
Am i doing thiscorrect?
Am i correct:
Is it save to say: When a cell dropped in 4 weeks to ~4.10 v you lose ~25ma?, and ~4 to 4,10v you lost 25-50ma?
Of course i take in consideration that there are cells from 1800mah to 3500mah.
So basically a could add up 25-50mah if a cell is on a "border" between two buckets?
Below a pic of my sorting trey, i think i am good to go?
Every comment or input is welcome
Thanks in advance, best
