How to solve it if a forklift battery has a short circuit?

The relationship between the internal resistance of forklift batteries and short-circuit capacity, as well as the relationship between the internal resistance of batteries of the same specification and model and the state of charge (SOC) in the polarization state. More than a decade ago, attempts were made to use changes in the internal resistance (or redox potential difference) of valve-controlled sealed lead-acid batteries for online monitoring of battery capacity and prediction and analysis of battery cycle times, but these efforts did not achieve the desired results. There are increasingly high requirements for the high-current charging and discharging capabilities of power lithium batteries, which necessitates minimizing internal resistance. Therefore, this article will further explore and explain the essential relationships between the internal resistance and capacity of some common batteries.
