Hey Guys n Gals!, …Just checking the capacity of my `older` 18650 stash
and now i have a dozen or so with capacity of around 1200mah
4.2v>3v@ 1A discharge rate
my question is,… do these have any use?
everybody must have a few eh!! :bigsmile:
keep as a backup, unless they wont charge past 4.1v… then its time to recycle them
1200 not bad. Can be used for low amperage projects.
Charge them up and keep them in boxes for if you go out camping or for a long hike, you can use them like disposables then with no worries about running them too low.
These is the best way
I threw away “loads” of trustfire/uniquefire or whatever they are ones a few weeks back. 20 odd cells in the trash because they were just poo. Blue trustfires, red and silver BRCs etc etc.
I just replaced them all with samsung cells.
I hope you didnt throw them out with regular trash, they have to be disposed of propery and not thrown in regular trash bin/contaner :D!

Why? Because they’re not dead when they start to fail — they’re getting more dangerous.
It takes a while before the internal crystals grow long enough to puncture the internal membrane.
Then the chemical reaction starts going fast enough to heat the battery up, boil out the liquid — flammable — contents
and may ignite from the heat.
With more than one cell in a box, things can get out of hand quickly after that.
At our local recycling centre all the spent cells are thrown into a big container about the size of a large bathtub with a hinged lid. It must be full of mostly AA, AAA, 9v, usual “household” cells. Is this an accident waiting to happen?
“Usual holsehold cells” are alkaline (or even carbon-zinc), which can’t sustain any high current even when short circuited. So no, I don’t think that’s a accident waiting to happen.
Just needs one bad lithium cell. I wonder if staff in these sorts of stores are even trained in the event of a battery bin fire. :~
Aw come on, wouldn't you guys like to see what happens when you toss 20-30 cells into a shredder? I sure would! (preferably from a long way away and over closed circuit video...)
Not if it meant exposing many potentially clueless people to hydrofluoric acid and other nasty chemicals.
