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.

but these are on the negative end not the positive if it was to prevent a short it should be on other end

@@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

​@@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.

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!

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

@@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.

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.
