The application provides a battery detection method, a battery electric quantity calibration method, a device and atomization equipment, and belongs to the technical field of battery management. The battery detection method comprises the steps of carrying out alternating charge and discharge treatment on a battery to obtain a plurality of first real-time voltages of the battery in a charging process, enabling the alternating charge and discharge treatment to be configured to charge rated electric quantity of the battery once, calculating real-time electric quantity of the battery according to initial electric quantity, rated electric quantity and charging times of the battery, obtaining charging voltage average values corresponding to the real-time electric quantity according to the first real-time voltages, and obtaining charging mapping data according to the real-time electric quantity and the corresponding charging voltage average values. Because the real-time electric quantity of the battery corresponding to each charging voltage average value is an accurate value calculated based on the initial electric quantity of the battery, the rated electric quantity charged once and the charging times, and is not dependent on the calculated value of manual estimation or theoretical curve, the accuracy of the mapping relation between the battery voltage and the electric quantity in the charging mapping data can be effectively ensured.
