description A method, an apparatus, an electronic device, and a storage medium for detecting water content in a battery are provided. The method comprises: obtaining a capacitance detection value of a battery to be tested by measurement; and determining a first water content value of the battery to be tested according to the capacitance detection value and a capacitance-water content relationship model. The capacitance-water content relationship model is obtained according to the relationship between sample batteries with different water content values and their sample capacitance values. By pre-constructing the relationship between the water content of the sample battery and the sample capacitance value and determining the water content of the battery to be tested according to the relationship and the capacitance value of the battery to be tested, the step of manually cutting the electrode sheet is reduced, and the efficiency of detecting the water content in the battery is improved.
