4 hours is generally enough time to significantly charge a car battery if it's relatively new and not deeply discharged. However, the full charging time can vary based on the battery's size and the charger's output power. For a standard 12V battery using a typical charger, 4 to 6 hours might suffice for a substantial charge but may not fully charge the battery. To ensure optimal performance and longevity, it's recommended to use a smart charger that can adjust the charge rate and minimize the risk of overcharging.
