Yes, you can overcharge a car battery, especially at 10+ amps. Overcharging a car battery can damage it, reduce its lifespan, and make it more likely to fail.
When charging a car battery, it is recommended to use a 3-stage automatic 12 volt/10 amp charger, which will automatically limit the voltage and the amperage during the charge cycle.
It’s important to disconnect the charger as soon as the battery is fully charged and not leave it connected for longer than necessary to avoid overcharging the battery
