In the test process
In summary, a battery with a voltage of 6V means that the electric potential on the positive pole is 6V higher than the electric potential on the negative pole. If the voltmeter leads are placed on the positive and negative poles in different orders, the reading will be either +6V or -6V.
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.
In my understanding there is a positive potential on the positive battery pole. It is only positive with respect to the other pole. Again, a height can only be positive with respect to a reference height. Shouldn''t the multimeter show the difference in potential between those two points of contact?

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.
Important Terminologies Related to Battery. 1. Cathode: The cathode is a positively charged electrode. During a chemical reaction, it gains electrons, which is called reduction. 2. Anode: Anodes are negatively charged electrodes. During a chemical reaction, it loses electrons, which is called an oxidation reaction.
Generally, the output voltage of the power supply is measured to be 26.8V. Generally, the equipment is required to work normally within the voltage fluctuation range of ±20%. For -48V system equipment, the required operating voltage range is -38.4V ~ 57.6V, but in fact we generally require the operating range -36V ~ -72V.

Same for 18650 battery cells. but we should have different way to find out the positive and negative pole of it. This is very important to know before you insert the battery to
What exactly is in the positive side of battery or other voltage source? Not quite, or not in solid conductors, anyway; think electrons and "holes" - spaces in the valence shell of an atom in a conductor. When an electron move one way to a different atom, it leaves a hole the other way; the ionised atoms don''t move in a solid, but the holes
$begingroup$ @user2612743 In an electrolytic cell you are the person that determines which electrode is positive and which is negative via the external potential. And this external potential doesn''t get altered in the course of the reaction because the "sucked in" electrons are transported away by the voltage source.

Hello Sorry for the Delay. Attaching the Schematic for reference. So here ideally I should get the voltage just with Positive and negative of the battery which is near the casing but when I am checking on the metal Casing (considering here as Chassis) I am seeing the voltage on multi-meter when i probe the negative terminal anywhere on the chassis .
So the lesson is, if you''re ever testing for electrical continuity between the battery''s positive and negative terminals (to see if there''s a short) make sure that all electrical items that would otherwise close a circuit are off/doors closed/boot closed. If there is still continuity, then the easiest way to find the real short is to
I understand that a 9V battery will produce an electrical potential difference/voltage of 9v across the positive and negative terminal,
When the positive shell voltage is large, it means that the PP layer of the aluminum-plastic film has been damaged, and the aluminum layer has been in contact with the electro-hydraulic in the battery. After confirming that there is
Install the battery in the vehicle, have someone in the seat ready to crank the motor. Watch the voltage drop on the battery. If it is a fully charged good battery at 12.6 volts it should drop no lower than 9.6 volts while cranking. If the battery completely drops dead to the 1 volt you were saying the battery is bad and a new battery is needed.
Parallel, positive with positive and negative with negative. 2 things connected with a wire will try to be at the same voltage/potential. If you connect 2 batteries with different charge states (let''s say 3.7V and 4.2V), if we assume negative as zero, in the positive pole, the 3.7 will try to rise and the 4.2 to decrease until they reach the same potential, this happens by moving charge from
