Battery charger – charging time

Last weekend, I recharged my battery, because the current Fiesta always causes problems with empty battery within a relatively short (stand) time, e.g. if you are on holiday for a week and the car is not moving. The app then sends the message “Vehicle is in deep sleep mode” and some comfort functions are deactivated. After just under 2 years, the first battery was defective and had to be replaced. In order to prevent this, I will now use the car. this autumn/winter, so occasionally connect to the charger (must). Sunday I did this and the charger showed me a quiet voltage of 12.6V. Can it be technically seen that the battery already has a voltage of 14.4V after about an hour of charging? The charger charges with about 6.5A and the battery has 60Ah.
