Indented Negative on Battery

[beckdg]

Could there be a short in the mod that's heating the bottom of the battery, weakening the metal and softening it enough for the pin to do this?

Especially two batteries?

hmm.... the mystery continues.

Wait.

What?

I hope that's not a serious question.

I was holding it comfortably in my fingertips while inspecting.

Heat softened metal would instantly cause 3rd degree burns.

We both know that's not the cause.

especially as mentioned, the top isn't being crushed, which, should be the first thing that would should it be a pressure thing.

I can show you otherwise.

The bottom is flat.

Flat surfaces give easier and withstand less pressure.

That there's goop behind matters not considering the materials.

I think it was aliens. Nothing else is making sense in explaining it. It must be like crop circles, or in this case, err, battery circles.

The Cromwell?!?! He wouldn't do that to a battery....or would he?

I would slowly discharge that until it reads below 0.2V on a meter before putting that in a recycling bin at the local store or the neighbors garbage bin.

It certainly wouldn't be going in my bin unless I discharged it myself.

How can I do that?

Depends how slow. Best way is a resistor (3.7 ~50 ohm resistor draws down at ~70mA so it shouldn't get too warm). Throw a fuse in the circuit to cover yourself just in case. Scenario two is a battery charger/conditioner that will essentially do that for you (but that's more expensive than some wire and a resistor).

Third option if you have a backyard, a bucket of sand, asbestos gloves and some goggles is take it out back and just short it. Saves the trouble of dropping anything off in the Home Depot recycling bin as there won't be much left to toss in there. Granted, this is the most irresponsible of the choices, but that's about the extent of my electrical knowledge extends as I've never had to do that. Hopefully someone a lot smarter will post a simpler and safer alternative.

Would make a good You Tube vid.

How can I do that?

The mech mod I personally think it was dented on.

Build a coil over an ohm or two with way too many wraps to over heat.

Then rig the button up to fire continuously.

Place it somewhere fire proof.

In a cinder block on a concrete patio would be ideal.

Then clean the contacts on that mech mod so you don't have to mash the button anymore.

Of course, assuming you have a mech mod is just speculation.

But it would make a whole lot more sense than believing that was damaged in a battery sled.

That would have to be one stiff spring unless it was dropped.

Even then, that would have to be a very narrow spring to make an indent that shape and size.

Just bring that to recycling...here we have boxes for that in every supermarket. Mask the poles with some tape.

DO NOT!!!

IF THAT VENTS IN A BATTERY RECYCLE BIN IT WILL CAUSE A CHAIN REACTION AND VENT EVERYTHING ELSE.

P.s.
You can leave it outside discharging for days.

I'd advise it if at all possible.

Tape will not prevent an internal short.

[Joergl100]

If there were an internal short, the battery had already vented. Tape reliably prevents from an accidential external short.

Personally I'd toss the battery, and I'd take a sledgehammer to that Chinesium grade P4Y D3 POS to make it safe....

...then get a good mod.

I truly dont own a mech lol.

Obviously.

But what's it going to take with that damage already present?

Neither you or I know.

Keep in mind I'm "known" (perceived) to be an extreme risk taker around here. Especially pertaining to batteries.

*I* (of all people) say it's not worth the risk.

Then there's something seriously wrong with either the handling of those cells... or more likely... that mod.

[Bunnykiller]

thats a pretty intense dent there.... IMO.. I would retire that one.
