@@kev-reviews This reminds me of the time I discovered that my high end Neptunian hyperdrive battery was actually a bunch of smaller batteries made in China! And spent a good amount of Galactic Credits on it, too! I overpaid, but it had a 'custom 'paint job', now I know why.
@@kev-reviews its for ease of manufacturing, old way can negative is harder to make with lithium insert. so they changed the can to positive shove the insert in and close the bottom. plastic is just extra insulation to prevent a short
You know what... The venting gaskets are likely deeper in the battery. I think what these gaskets are for is to prevent your device from shorting the can to the negative should the wrapper get a hole in it. If you look, there is gap between the center and the outer. The can itself is the positive while the center part is the negative. But if you had a device with a large spring (and the plastic wrapper broke), it could touch both the center and outer part of the center, which is the can and cause a dead short. So it is probably there as a fail safe should the wrapper become damaged.
Interesting that the vent end of alkaline cells is at the cathode end (-). On advance/ultimate lithium, it's at the anode end (+). I learned something today! Good luck with the real world testing. Good way to put a vintage CD Walkman to good use!
@@kev-reviews It's interesting that this feature is not shown in their "Powerseal Technology" cutaway view of the cell. Take a look at Dr. Gough's Tech Zone article Great AA Alkaline Battery Test - Pt 4: Cell Physical Characteristics. You will see this is indeed a diverter to spread any expelled electrolyte under the wrapper. I learned something today! I was surprised to see the vent end of the alkaline battery is at the (-) cathode end, not the nipple (+) anode end. That explains why there is a crimp around the body at the cathode end: they have to install the valve. Lithium cells have the vent at the (+) end, Alkaline at the (-) end. You can often see the holes on the Energizer Lithiums at the (+) end.
The only way to know if these batteries are the same is to chemically test them. The chemistry from battery manufacturer to battery manufacturer is similar, but not exactly the same. The physical build similarities can be caused by them using the same or similar machines to make the cells. Another much easier approach you can take is to buy a battery meter that can read the internal resistance and a scale that can measure down to the milligram scale and weigh them.
used to be i bought the name brand Duracell and energizer because they were less likely to leak and had a warranty also made in America better quality but now, they are all Chinese garbage too
Check them when you buy them. They seem to be made in many different places. It's getting hard because the packaging doesn't say, and you can't always see it on the cells. I never buy the China ones. I haven't had any trouble.
@@KC9UDX yeah the jerks from Duracell write on package might be made in usa or somewhere else look at the batteries inside the package usually a bit hard to read in package.
4:00 all 3 of them look to be the same design, or at least use the same machines to make them. 5:00 an even cheaper version that seem to be made by the same presses. 6:00 again made on the same presses. china mass manufacturing at it's finest.
This is the drama the internet was made for
😂

4:51 Don't let anything metal or conductive touch across the bottom. The can is positive and the button in the middle is negative.
Thanks

but these are on the negative end not the positive if it was to prevent a short it should be on other end
@@ranger178 The entire can is the positive terminal. The small circular spot in the center of the bottom is the negative. They come close right there.
@@tarstarkusz must be crazy new way the chinese are making batteries then because most of my batteries have can is negative
@@ranger178 That's lithium. They do have a negative can. But most alkaline batteries have a positive can.
Your battery investigation has been very interesting so far.

Seems like the cap may slow how fast the leaking makes it to the contact area by diverting it and spreading it out to the wrapper.
Possible. And/or it allows any pressure or vapers to have vent space further away from a device

Can you review energizer max plus?
I’ve never seen max plus and don’t have it on their site
Interesting, but what is the capacity of each Battery for comparison?

Maybe you take the cap off to recharge them?
Alkaline. Not made to be recharged and can explode if recharged

I will not buy Duracell's anymore because so many have leaked.
Thanks for sharing. I’m seeing a few people say that
And the point was?
8 minutes of literal nothingness.

@@ranger178 exactly!
2:00 it's the SAME battery!!
Oddly similar, right? Even the performance from Voniko-to-Chinagizer is eerily similar.
