A short circuit happens when there is a low resistance path between the positive and negative terminals of a battery, allowing current to flow freely between them. This can happen if the terminals are touching each other, or if something else is connected across the terminals that have a lower resistance than the internal resistance of the battery.
If a battery is short-circuited, it can cause a fire. The battery will start to overheat and the chemicals inside will catch fire. This can be very dangerous and should be avoided. When a battery is short-circuited, there is a sudden flow of electricity from the negative to the positive terminal. This can cause an explosion and release toxic fumes.
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.
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.
If your battery is shorted, it means that there is a direct connection between the positive and negative terminals. This can happen if the battery case is cracked or damaged, or if the terminal connections are loose. A shorted battery will not be able to hold a charge and will need to be replaced. What Might Cause a Battery to Short Circuit?
If you short-circuit a lithium ion battery, it will discharge very quickly. This can cause the battery to overheat, catch fire, or even explode. Short-circuiting is one of the most dangerous things that you can do to a lithium-ion battery.
