Says: if im sitting in my car will it kill the battery really fast or faster if i turn the key half way so i can listen to the radio but not start the engine? will it drain it less if i turn the key back wards?2. don r Says: Put the switch on "acc" (- accessory- )so the rest of the components don't draw current. The radio draws little power unless you have a booster amp that uses more.3. The-Razors-Edge Says: The car will use the least juice in the accessory position, which is when you turn the key backwards. The other position you are referring to is "on" or "run" Tag: Will doing this drain the battery on my car?
