But recently I got one for 5 dollars that comes from a laptop that got broken, and it was near 50% charge
So perfect for storage
They work great and are powering my 6 cell powerbank
some had low voltage but they got 4.1v easily
these genuinely look like a death trap
but if you use them a little, they die after a while
>stepping on li ion pouches
yeah okay
Not in my experience, it's luck/informed purchases
I got one battery that had terrible cells
Rest charges to 4.18v, so all's well
and the voltage doesn't fall considerably
what's your routine for checking cells?
they look great if you ever wanted your own land mine
depends on yoru budget tho
nvm if its going to be in your car i'd get something bigger
i don't know, it was a 6 cell HP laptop battery that was clearly dead. most of the cells were 0.8v, some were 2.6v. i jerry riged something to revive them. just a 18650 holder with one of that little charging boards glued together. worked OK, most of them got 4
4v or more
if below 2.5v, throw away
sec
i going to check those samsung
Ok
PROVEN STEPS
1. Measure cell voltage, if lower than 2.5v, throw away
2. Charge. If they get hot, throw away
yes yes
more deals

3. Measure voltage after charging. If not 4.1-4.2V, throw away
4. Wait 30 min. If voltage fell under 4V, throw away
@Tervy im seriously considering those dragon balls
I don't know what I'd do with them
5. Store in a cool, dry place for 3 days. If voltage fell by more than 0.1V, throw away
And there you have it
Or where I'd put them
@TCxUFATIME if you really want some find glass ones
those resin ones are nice probs incase you go to cons etc
well, i left them for a month or so, after that, i checked voltages and most of them (of the ones that could get some voltage) droped
