Can the car charge the battery if it only starts but doesn't run?

The car can charge the battery if it only starts but doesn't run, but the charging effect is not good, and it takes a long time to fully charge the battery. The instantaneous power consumption when starting the car is very high, and it takes a long time to replenish the battery's power. It is recommended that if the car is not used for a long time, the negative terminal of the battery can be disconnected to effectively avoid battery discharge. The power source of the generator comes from the engine. After the car starts, the engine begins to work, and the engine transmits power to the generator through the belt, starting to charge the battery. However, the charging efficiency is different between idling and driving states.
