I salvaged a lot of laptop batteries circa 2010, they were old by then. Presumably 5 years old or how many years old as a guestimate.
They don't throw away new equipment.
I parsed through the cells, and threw away about half, the ones that did not hold charge. The remaining ones I kept. I am not real sure of the original capacity, probably about 2000 Mah - just think 2005 or 2007-2008 time frame and you will have the right idea. Either a decade or even older.
I need to pull out the bag and recheck them again, I left them all charged, I need to parse them and throw away the ones that self-discharged.
I wonder what percentage of the original capacity they hold - which wasn't high to begin with. Not 3500 mAh you might say.
I also have a set of older 18650 that I got myself, new, circa 2010 and up. They are much higher capacity like 2900 and 3100 mAh cells, Panasonic. I still use these, along with the latest-greatest.
I wonder if I can use the really old ones 10-12 year old ones - in place of primaries. That is a one-time use. Since I have what seems to be 100 or more. and realistically they will just lay there and degrade into oblivion.
