Full battery short circuit
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.

Identification of Internal Short-Circuit Faults in Lithium-Ion
Internal short-circuit (ISC) faults are a common cause of thermal runaway in lithium-ion batteries (LIBs), which greatly endangers the safety of LIBs. Different LIBs have common features related to ISC faults. Due to the insufficient volume of acquired ISC fault data, conventional machine learning models could not effectively identify ISC faults. …
Can a Car Battery Have a Short in It?
Voltage Test: Use a multimeter to check the battery voltage. A fully charged battery should read around 12.6 volts. A significantly lower reading could indicate a short. Current Draw Test: With the vehicle off, measure the current draw. An unusually high current draw when the vehicle is off can be a sign of a short circuit.
