Batteries: Function, Types & Properties | Vaia
It suffices to know that some chemical interaction causes the cell to have a difference in electric potential (potential difference or voltage) between two points of the battery, which we call its poles. The positive pole is defined as the pole that positive charges are repelled by, and the negative pole is the pole that is not the positive pole.
Why is there no current flow when I connect two opposite …
If you connect a conductor to a battery terminal the conductor becomes the same potential as the battery terminal, and the potential difference becomes 0, so there is no electric field. If you connect the - terminal of a battery to the + terminal of another battery, the contacts will be at the same potential (because they are conductors).

How to Tell Positive and Negative Terminals on a Car Battery
Park another vehicle by your car and turn everything off. Park the other car close enough that a set of jumper cables can reach both batteries. Cut the engine on the booster car and turn off all the accessories in both cars, like the interior lights, radio, and AC. Most cars have their batteries under the hood, but some may have the battery in the trunk.

Cathode (positive electrode) The nature of cathode in a lithium ion battery affects the average voltage and overall battery capacity. Depending upon the type of lithium ion battery, the cathode can have cobalt, nickel, or manganese with lithium oxide. These active materials increase the conductivity of lithium. Electrolyte
Battery pole type
However, it would be good to just look at the existing battery to see for yourself. Normal large poles have a diameter of about 17.5-19.5 mm at the positive pole and 16-18 mm at the negative pole. The thinnest (or Japanese type) poles have a diameter of about 12.5-14 mm at the positive pole and 11-12.5 mm at the negative pole.
Is the positive terminal of a battery positively charged
Yes, there is a difference of charge distribution between the two poles, which causes the electric field. When you join the two poles with a conductor, the charges will "feel" this electric field and start moving in the conductor from the positive pole to the negative, thereby reducing the charge difference between the poles.
Continuity between positive and negative battery terminals when battery ...
Thanks to all who replied. I did a bit more troubleshooting and found the culprit. For those interested, the answer to my original question is NO – there should not be any continuity between the positive and negative battery terminals when the battery is unplugged (as this would indicate a short circuit!).
