Can you Keep Radio on When Car is Off?

If you are using a modern vehicle, you do not need to worry about the battery draining as a radio only uses minimal power to operate. 

How to Keep Radio on When Car is Off?

There are many methods you can follow to keep the radio on while the car is off. These methods may vary according to the vehicle type and the model of the radios. Some methods drain a little power from the battery, and some do not need to be powered by the battery. Some methods will need additional equipment like a radio adapter or power converter. If you use a battery charger, it will dually function as it charges the battery while playing the radio. 

Turning on the ACC or the Accessory mode is the easiest way. There is no need for additional fixtures in this method. Accessory mode is the state at which the engine stays off, but the accessories like the radio, wiper, windows, and lights inside the car are allowed to operate. There is no specially designed button or command for this in older cars. On such occasions, you can enter your car into accessory mode manually. All you have to do is park your car and turn the switch just one notch. This will make the accessory mode on. 

If you own a modern car, you can turn on the accessory mode via the on/off switch. Here you have to turn the switch on without stepping on the brake. 

If your car is manufactured between 2012 – 2015, the steps are different. First, you will have to press the brake and release it. Next, shift to Park, pulling the hand brake. Again, step on the brake once and go to Neutral mode. Without releasing the brake, switch on the vehicle and then release it. Finally, move to Park mode.

If you own a Gated Manual Shifter, firstly, you need to go to Neutral when the car’s engine is on. Move the gear to the right and hold it while switching off the engine. Wait for the radio to continue, and you can take the hand out from the gear lever. 

The certain accessory will require small power from the battery to operate. But there is no power wastage when you just keep the vehicle in ACC mode without using any gadgets. If you see a strange drop in battery power while listening to the radio in accessory mode, there is something wrong with the interior structure. You will have to get the help of a mechanic to find the reason and treat it. If you are a radio listener who often uses the ACC mode, it would be better if you do regular checkups to identify if there is an issue with the system. 

How Long Can you Keep your Car Radio on Before Battery Dies?

If you listen to the radio continuously for 10 or 12 hours while in ACC mode, your battery will go dead. On the contrary, if you use the radio in the same state for a short time, there will be no threat of the battery going dead because it drains less power. The battery type, age of the battery, vehicle condition, and the accessory you have turned on are some facts that directly affect battery draining.

For instance, newer models are equipped with audio systems that attract very low electricity from the battery than the older models. If you have modified your audio system with powerful speakers or subwoofers, there will be more energy consumption. If the battery is newer, it is totally OK to listen to the radio for lengthy hours. But if your battery is near its off mark, there will be more impact and will cause the battery to die while you are enjoying in a car park. 

Anyway, if you are using the radio when the engine is turned off, you should expect your battery to go dead before its average life span. That is why it is always advised to perform regular maintenance and checkups of your battery.
