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

i tried to make a power bank with the 2 with better voltage, but it doesnt work very well

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

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

but for showcase go with the glass

yeah, i need some fresh batteries

where to check coupons? 10$ for 2 is more than I'm willing to pay
