How many kilometers does it generally take to fully charge a car battery?

Taking a 12V60Ah battery as an example, the charging method is as follows: use constant voltage and current limiting for charging, charge at a constant voltage of 14.8V with a current limit of 15A for 16 hours, then charge at a constant current of 3A for 4 hours, totaling 20 hours. Below are the criteria for determining when a battery is fully charged: Battery: A large number of bubbles are generated inside the battery, showing a "boiling" phenomenon. Terminal Voltage: The terminal voltage rises to the maximum value and does not increase for two hours. Electrolyte: The electrolyte rises to the highest level and does not increase for two hours. Precautions: If charging is needed, turn off electrical devices as much as possible.
