The length of time required to change a car battery will depend on a variety of factors, such as the type of battery being used, the condition of the battery and the complexity of the installation. Generally speaking, an experienced technician will be able to change a car battery in approximately 20-30 minutes if all the necessary preparation and safety checks have been completed. This includes disconnecting the old battery and cables and removing the old battery. The technician will then proceed to install the new battery, connect all the cables, reseal the battery, check water levels and install the battery clamps. Once all these steps have been completed, the technician will then fill the cells with electrolyte, test the voltage and recharge the battery. Most technicians will then make sure the ignition system, lights and other electronics are functioning correctly before awarding a final check.
