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.
The short circuit current of a battery can be estimated using Ohm’s Law, which states that Current (I) equals Voltage (V) divided by Resistance (R). In the case of a short circuit, the resistance is extremely low, nearly zero. So, the formula simplifies to: Short Circuit Current (I) ≈ Voltage (V) / 0
A battery short circuit occurs when there is a low-resistance or no-resistance path between the battery’s positive and negative terminals, leading to excessive current flow. The short circuit current in a battery can vary widely depending on the battery type, capacity, and internal resistance. It can range from tens to hundreds of amperes.
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.
For large batteries such as those used in Power Stations, short circuit currents may exceed 40k amperes. Even when the battery is not fully charged, the short circuit current is very similar to the published value because the internal resistance does not vary substantially until the cell approaches fully discharged.
Estimated short circuit values can vary widely depending upon the test method and measurement technique. Multi-stepped discharge test methods that use a large span in current and voltage provide the best accuracy in estimating battery short circuit current and resistance.
