Hello! Forgive me, I'm new here, this is my first post. I hope I'm doing this right!
I have a number of cells here that I need to test for a project -- six teal ones marked --
ASO FM1L224EH 8219##
(last two digits differ on each cell, so likely a serial number)
-- plus six more blue ones marked --
PH Great Power Li-Ion
ICR18650 2.2Ah-AF 3.7V
20161028
-- with the date or lot code centered and the rest of the text, erm, not so much plus four MORE cells, very old ones (these came out of a rather damaged pack, I could only save about half of it, from a Pentium III Dell Inspiron) with sort of red / burgundy wrappers, marked longitudinally (!!) --
FKAF4
0####
-- with the bottom number likely being a serial number. The leading F on the top is aligned with the second digit, and there is a "C" hovering above and a digit hovering below each. The serials (?) and digits for each that I have are --
027449 / digit "4"
027671 / digit "2"
037210 / digit "5"
037414 / digit "5"
-- aaaaand finally (yeesh!) an octet of Walmart's (in?)famous Westinghouse (lol) "2000mAH" 18650s that I got for $15 per 4pk here. Photos later, if that's OK -- I'm tired and I want to be sure I'm in the right spot first.
I do have an equipment question, though -- I've seen what can happen when stupid people do stupid things around these cells (thanks, YouTube), and I know that, like anything else dangerous, if you treat it with ignorance it will mock you and hurt you, but if you treat it with respect -- including that which involves taking the time to understand how to treat it right, you will be just fine. I come from a background in electronics and PC hardware, but this is an area in which, to be honest, I know very little -- and the cost of my nerdiness is, erm, I'm on a fixed income in a tiny apartment. Money's tight.
Can someone kindly suggest what the cheapest trustworthy equipment set would be that I could get to reliably determine capacity of each cell individually, preferably on Amazon (I live in a small town in the upper end of the SE US, and they don't let me out much) and what a safe test procedure would be in order to use it?
