Destructive ideas welcome (YT Video in OP!)

I have a new Samsung 30Q that has a self discharge problem. I put it on the shelf fully charged a year or more ago, and found it flat 0.0 volts. It’s not a lot of self discharge, I tested it at about 0.1 to 0.2 volts per hour. So I can charge it up for one last farewell party.

Any ideas on what might be fun? I can share the results.

And yes I know this is dangerous, I have proper safety gear. And will charge it outdoors.

hi, if you’re storing cells its not a good idea to fully charge them, around 3.5-3.6V would be better.

As for the farewell party. maybe shoot it with an air rifle, or short circuit it.

Yea I know about best storage voltage. But life happened.

Well this is America, so my rifle isn’t an air rifle :stuck_out_tongue: That could be fun. And being at a safe distance would be easy.

1000 yard shot :slight_smile:

Observing all laws and appropriate safety precautions, I think I’d like to see it discharge EXTREMELY rapidly.

Full 8AWG short.

Measure current draw with a clamp meter.

I like that idea a lot, but I don’t have a clamp meter.

Cu is sooo last year. Make your own superconductor. Liquid nitrogen not included; and it won’t superconduct very long as it heats up!

How about Lucky Luke style? Throw it up, bang - bang, falls down with two holes. :partying_face:

Hum, put it reversed in a flashlight without Reverse Polarity Protection and measure the heat :smiley:

Maybe with some matches inside and flamable liquid too :smiling_imp:

That would be a Hell Of A Shot — a 18650 at 1000 yds — Please video

He’s joking, the best marksman would spend all day trying to hit that at 1000yards with consumer grade guns and ammo. And still never hit it.

you think :smiley:

I remember a few years back word going around the internet that Apple had released an iOS update that allowed the latest model of iPhone to be recharged in a microwave…

Find some Ukrainian guys with swim-goggles (safety equipment) and a hammer and/or axe.

Ooh, ooh. 12ga shotgun shell (~18mm), cut down to remove the shot but leave the wadding, drop the 18650 in there musket-style, and blast it into a brick wall.

18650… that’s a little loose for a 12 gauge and a bit tight for a 16 gauge… but I bet it would fit nicely in a in a high-brass 3” 12g birdshot shot cup.

Just Saying…… :beer:

Or, maybe you have a pair of large jaw vice grips or channel locks that need heat treated?

Hence “leave the wadding”. Let that do all the work. :laughing:

That shotgun idea could be impressive.

Or it’s possible the sidewalls of the battery will buckle due to the high acceleration involved, jamming the battery inside the barrel, likely damaging the barrel and potentially even creating a risk of overpressure.

I wouldn’t recommend it without taking significant precautions.

don’t use a full choke barrel :cowboy_hat_face:
