A battery is a source for electricity. A flashlight and a radio are not a source for electricity.
Most computers use a mix of battery power, as well as electricity, as their energy source. For instance, your cell phone works through battery power that you must charge with electricity when it runs out.
Yes - radio, spark plugs, headlights, tail lights, turn signals, overhead light, etc. All of these use electricity from the battery or alternator.

You shouldn't use anything that uses electricity like lights, radio, etc. when the engine is off

what is the transformation of energy in battery-operated radio
The radio doesn't have a battery. It uses the vehicle electrical system / battery. If the power to the radio is interrupted, you will have to reenter the presets. Make sure the fuses for the radio are not blown.
