When a battery is disconnected, power to the vehicle's electrical systems is typically supplied by the vehicle's alternator, which generates electricity while the engine is running. Additionally, some vehicles may have capacitors that can temporarily hold a charge and provide power to essential systems. However, without a battery or a backup power source, most electrical components will not function effectively.
