The basics of short circuits in power electronics systems
A short circuit will occur where there is a low resistance connection between two conductors that are providing a circuit with power. This leads to the generation of an excess of voltage streaming and causes an excessive current to flow through, which will go via a ''short'' (unexpected) route and cause a short circuit. There are two main
batteries
A really simple theoretical approach treats a battery as a constant voltage source -- but this only works for applications where the combination of current draw, run time, and sensitivity to voltage drop is low. The initial short-circuit current for such a battery is ~1 Ampere. The dependance between the useful capacity and the discharge

ELI5: What does it mean for a battery to ''short-circuit''?
As the battery voltage stays the same, resistance is close to zero due to short circuit and current draw goes up. A short circuit battery would be caused by having the + and - ends of the battery connected together when they should not be. To simplify how a battery works: There is a different number of electrons on each side of the
voltage
The wiring to a high current battery, like a car battery for instance, will invariably be protected by a fuse, which opens in the event of a short circuit. The wiring to a low current battery may not need protection, if the short-circuit current is low enough for any practical wire.

When I reconnected the circuit for another 2 minutes the voltage didn''t decrease and the battery wasn''t hot. I tried a few more times (after waiting 30 minutes) and the same pattern occurred: the battery drained a bit, but after some time it seemed as if the current stopped during a short. I used the battery to power up a led, it still works.

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.
How do you calculate a battery's short circuit current?

What is a short circuit battery?
ACTUAL SHORT CIRCUIT CURRENTS FOR VRLA BATTERIES “shorted” lead acid battery has the capability of delivering an extremely high current, 100 to 1000 times the typical discharge current used in most applications. Electrical systems using batteries must be properly protected to avoid potentially dangerous fault conditions.
What happens if a battery is short circuited?
Often, the peak short circuit current occurs within 5 to 15 milliseconds. Without some form of protection such as a fuse or breaker, a short circuit condition can cause permanent damage to the battery. In effect the battery can itself becomes the fuse.
What is an internal short circuit?
An internal short circuit is a serious electrical fault that can occur within a battery. It happens when two or more electrical components inside the device come into contact, causing a sudden surge of current that can damage or even start a fire.
What happens if a battery is plugged into a cathode?
When the cathode and anode of a battery are connected directly, bypassing the internal resistance of the battery, a short circuit occurs in the battery. As a result, a large current flows through the short circuit, creating heat and possibly causing the battery to leak or explode. There are two main kinds of battery short circuits.
