That information varies from make and model but typically is eight hours or overnight. Consult your owner’s manual for more details on your specific model and year of manufacture for charges and installation instructions specific to that vehicle.
Car batteries come charged from the factory unless they are an unusual size that requires special treatment in order to fit your vehicle. The charge on your new battery will have dissipated during shipping, but this can be replaced with an overnight charge that reestablishes the chemical balance of lead-acid batteries.

Whether you should charge a new car battery depends on the condition of the battery, the state of charge when you purchased it, and whether it’s a dead battery or simply not working properly.
In many cases, you should charge a new car battery at least eight hours before installing it in your vehicle. Follow your owner’s manual for specific recommendations.
