Does a car need to be started to charge after replacing the battery?

It depends on the situation. If the battery has a charge indicator, you can check the indicator to see if the battery is fully charged and does not need charging. If there is no indicator, you can also use a voltmeter to measure the open-circuit voltage of the battery. If the voltage is above 12.75V, no additional charging is required. Newly purchased batteries are generally not fully charged, but they are not too low either, so there is no need to worry too much about power loss. As long as the engine is started, the battery will automatically charge. As for how long it takes to charge a car battery, generally speaking, driving normally for one to two hours is sufficient to restore the battery to normal charging levels.
