Even if the voltage source remains at the same level, the terminal voltage will go down with current since the drop across the resistance goes up with current. There are also again chemical affects, so the voltage source doesn''t stay fixed either. As the battery ages, both the voltage source will go down and the internal resistance will go up.

What is voltage when there are no resistors(short-circuit).
In an ideal model, the voltage across a short-circuited battery is undefined, as the ideal battery always supplies a certain voltage drop, and an ideal wire can''t support any voltage drop. If there''s no resistance, once current starts flowing, it doesn''t need any voltage to keep going. For example, in a superconductor, current keeps flowing

A battery''s short circuit current is typically estimated by dividing its open circuit voltage by its internal resistance.

12v dropped across 5mohm would give a current of 2400A. The CCA of the battery is way below that, so the wrench is not limiting the current, the battery is. Contact resistance is a further complication. In the case of a battery shorted by a wrench, there''s likely to be a plasma arc between the contacts, which can have a very low resistance indeed.

ELI5: What does it mean for a battery to ''short-circuit''?
A "short" is an electrical connection in a place there shouldn''t be one. A short circuit battery would be caused by having the + and - ends of the battery connected together when they should not be. If you dont put something else (a resistor) in the electrical path to slow down the energy, the energy turns into heat.

Why is current through the short circuited wire not zero?
Two points on a short-circuited wire are not at the same potential—an ideal battery has a voltage difference between its terminals by definition, and that voltage difference has to be dropped somewhere. When there are no proper resistors in the circuit between the battery terminals, the wire itself is now the "resistor," just with a voltage drop equal to that of

Why don''t batteries get drained instantly when shorted?

Real-world "short-circuit" current often increases with series connection as the cabling might be the actual limiting factor. But it is always below the maximum short circuit current in any case.

What happens if a battery has a short circuit?
In electronic devices, a battery internal short circuit can cause permanent damage to the device’s components, making it unusable. Preventing internal short circuits is essential for maintaining the safety and functionality of electrical systems. Regular battery maintenance and proper installation can reduce the risk of internal short circuits.
What determines a battery's short circuit current?
To recap: the short circuit current is a function of several variables but is mostly determined by the nominal voltage and internal series resistance. If the positive and negative terminals are connected by a wire then the battery is by definition shorted. What the voltage of the battery is does not really matter.
What is a battery short circuit?
A battery short circuit occurs when the positive and negative terminals of the battery come into contact with each other. This can happen if the phone is dropped or if the case is damaged. When a battery short circuits, it will usually cause the phone to turn off. In some cases, it may also cause the phone to heat up or even catch fire.
What are the different types of battery short circuits?
There are two main kinds of battery short circuits. When two conductive materials come into contact with each other and a low-resistance channel is formed for the flow of electric current, an external short circuit occurs. This can lead to a sudden increase in current, overheating and possible damage to the electrical system.
How do you calculate a battery's short circuit current?
battery’s short circuit current is typically estimated by dividing its open circuit voltage by its internal resistance.
How can a battery prevent a short circuit?
Battery system circuit resistance, state of charge and temperature can reduce the nominal zero-voltage short circuit currents. Potentially dangerous short circuit conditions can be prevented with a better understanding of battery and circuit protection operation.
