No, a battery charger is designed to charge a car battery, not discharge it. The purpose of a battery charger is to provide electrical energy to the battery in order to replenish its charge.

If a car battery needs to be discharged, it would typically be done by using the battery to power the vehicle or by using a specific discharging device. **

It is not recommended to deactivate the auto-stop feature in a car as it is a safety feature designed to help reduce emissions and save fuel.

A USB car charger typically draws a very small amount of power from the car's battery, so it should not noticeably drain the battery under normal usage.

It is generally safe to use a USB car charger while the car is running or for short periods of time when the car is off. **
