18650 harvest problem

Ok so ive successfully harvested twice with no problems but now I ran Into a problem im worried about.

When I move the yellow wire there is a mini spark almosr like a tiny lighter flame and im scared to remove it and cant dispose of it since every place is closed now. Can I still rush pull it off or will it blow up in my hand.

Im not actually trying to remove the yellow wire but the slightest movement to get the top two cells out causes a spark

I’m not sure this is the type of problem I would want remote support for. Probably best to put on some safety gear and figure it out.

I just want to dispose of it safely cause idc about the cells at this point but I cant take it anywhere and obviously outside trash cans will start a fire.

I had that happen once with a laptop cell pull. i moved it outside, put on some heavy leather gloves & a full face shield, then pulled the wire tab out quickly with a pair of needle nose pliers. it sparked only for a second then everything was ok. I finished removing the 18650 cells after with no problems.
Every case is different though, so if you do go ahead and remove it quickly, take great caution & make sure your wearing heavy gloves and face protection, and do it out in the yard away from flammables.

Took your advice and it all worked out thanks. As far as the cells themselves if they are testing above 3 volts everything is fine or should I dispose them

I’ve harvested more than 10 packs but never had that problem.
Normally I cut all the wires first before pulling out cells.

There are some excellent safety tips above.

if they all test over 3 volts each after resting un-used or conected to anything for a hour or more, and you have a good LiIon charger like a Nitecore i4 or a Opus 3100, then charging them will be ok. If you have the BT3100, you can test the internal resistance and the capacity of each one.
