Is this a battery?

Could be a high wattage resistor. Use a multimeter, check it for voltage, if nout, check it for resistance.

>>933532
> They have a positive and negative terminal
Resistors are not polarity sensitive anon.

>>933531
Could be. Could also be a fuel cell. It appears to have some sort of nipple on it along the edge which could either be a gas vent or an inlet/outlet for electrolyte. Is there another nipple behind your thumb or on the opposite edge? Does it feel heavy like a battery or hollow? Does it sound solid when you flick it with your finger?

It appears to have a QR code on it as well. Take as close and clear a photo of it as you can (like, prop your phone up with something so hand shake doesn't rape it) crop out the QR, blow it up some in paint then save as a monochrome bitmap (so you are left with black and white, hopefully clean enough to read). Dump the resultant image into a QR reader and see what it spits out. You might get a part number or some other type of identifier, work from there.

There is no other text on there I assume?

There's apps that read QR codes, anon.

>>933555
There are, and if you can find one that is capable of reading a code that is the size of your fingernail, which has been printed on a reflective surface by making slightly less reflective etches, that would normally be read by a reader with job specific optics in an industrial/factory setting, let us know. A straight up photo, processed as described, *might* catch it, a QR reading app on its own? Never.

looks like a individual prius battery cell

>>933599
yup. battery.

Oh cool. I did find these at a car shop. Of course...if they are in the scrap pile then they might be junk.

hey feel heavy and solid like aluminum. I will test them later, just have to get around to it.

If it is a prius battery cell, what is the standard voltage for these? 12 volts like a car?

Also, what's inside these batteries? are they lead acid or NIMH?

I can't seem to find info, pictures or video of these cells being opened. what's in them?

>>933713
Lithium ion. Be careful if you pop them open; the electrolyte is not particularly corrosive but lithium is fairly reactive and may catch fire spontaneously.

>>933715
2015+ is lithium ion
1997-2014 is nimh

>>933713
>>933715
Yes it's a Lion cell, even with low charge it may burn your house down. Especially faulty cells love to burst into flames.

May show no voltage at terminals, sometimes these things have weird safeties that house the voltage.

>>933736
Yeah as I understand it lithium can (and does) form little dendrites that can detach from the electrodes and just float around merrily awaiting the opportunity to dump some charge. I suspect that within that case is a number of pouch cells jammed in pretty tight.

>>933715
Is the lithium in its elemental form, then?

>>933825
Not exactly; my understanding is that it's mostly complexed (intercalated really) into graphite at one of the electrodes (the anode I think; too lazy to google). It seems unlikely that one could recover elemental lithium from a cell (at least on a DIY basis).

Looks like a capacitor

y'all niggas dont know a flux capacitor when you see one?

shame.

>>933595
Course it will.

That's what QR is for.

The three alignment spots let the reader rotate in three dimensions any QR that's not perpendicular to the camera. The _#_#_#_ pattern between them lets the reader correct any non-linearity created by fisheye lenses or curved surfaces. After that there's Reed-Solomon error correction.

QR's entire point is that it's easy to read from a low-quality camera feed.

Hell, if OP had posted a PNG, you could probably have read it from that.

Absolutely a QR app would be able to read this. No-one's going to put an illegible QR code on something, that would defeat the point.

Can you imagine guys in the factory having to pull out photoshop every time they need to install one of these things?

Hopefully you'll find it useful.

I am well aware of how QR works. The QR's printed on parts are different to the QR's printed on billboards. Yes, they use the same scheme to read and encode data and are functionally identical, but they are made small to save size, and the factory uses zoom lens equipped (or scanning laser) hand readers to scan them.

> Can you imagine guys in the factory having to pull out photoshop every time they need to install one of these things?
No, but I can imagine they don't have smart phones with cheap app's either. They have handheld imaging scanners full of dedicated optics like pic related (which I install, amongst other factory process control systems) which could read inset QR from a foot away.

I assure you, I know what I'm talking about.

>>934029
Tried that app on QR in pic related for shiggles (which is much better contrasted than OP's part) and it couldn't see shit, just like the QR reader I already had installed. As I say, these codes are not made to be read by consumer level cameras on consumer level app's, they are factory and inventory markers, designed for industrial use only, readable only with specialised gear. Without said specialised gear, your best hope is to get a close photo, scale it up, convert it, and hope the inherent error correction of QR's that >>934028 alludes to gets you over the line. Unless you have a hand scanner like pic related of course.

Sage, because OP has a prius battery and none of this is relevant.

Well I checked them with a multimeter and three of them read at full charge, 7.4 volts while the fourth was at 6.3volts.

Of course this could be a clever ruse as a battery can read full but fail under load

Have to test them on something

Also, If these are out of a car, how the heck would I charge these?

Just saying. Is installing expensive tech that has been made obsolete by smart phones a lucrative field? I'm trying to understand why you're so against these apps

>>935093
Look up how the radio controlled car, plane, helicopter enthusiast people recharge their batteries. The same chargers will work, they work for many different battery sizes, and some chargers even detect and cope with faults.

>>935167

maybe you need to relax and accept the fact that not everything is designed for consumers or their apps ok? No one is against anything.

This shit just isn't made to be read by a smart phone ok? different applications have different parameters. try not to take it personally...sperglord...

>>935907
>shit just isn't made to be read by a smart phone
But... It can be read by a smart phone. Why does this upset you so much?
