Why haven’t we started already?
How Does a Modern Car Battery Work?
To understand the link between radio and car battery drainage, you need to know how the car’s battery works. Like all electrochemical batteries, modern cars also contain ones that convert chemical energy stored in them to electricity.
You might have come across several music enthusiasts complaining about how their car battery dies. However, the cause usually lies in several factors that they are not paying attention to, like devices connected to your car.
Driving multiple short rides may also lead to battery drain since it uses more power to start the engine and keep it running.
Will Leaving the Car Stereo Switched on Drain the Car Battery?
Since the radio system uses the power that indirectly comes from the battery of your car, it adds to the drainage. Moreover, the amount of energy your radio requires depends on the type of radio system you have installed.
A car’s radio does not use too much power, unlike a hungry subwoofer. Therefore, the vehicle battery dies if you have other things switched on like the fans and lights. Also, if you are using powered speakers or visual displays within your sound system that may lead to the car’s battery drainage.
Follow the tips below if you wish to keep listening to your radio stations without draining your car battery.
Tips You Can Follow to Avoid Draining Your Car Battery While Playing the Radio
If you think that there could be other factors contributing to your car’s battery drain, turn them off. Try switching all the lights, fans, and AC off, and then test your battery life by turning on a radio or without it. Keep a note of your observations to better evaluate the issues.
Whenever you think you will be traveling a long distance or for a few hours, ensure that you start with your battery charged fully. That way you can listen to the radio and travel as far as possible without draining your car battery.
The next method you should follow is to tune in to the right frequency to get the most out of your car stereo system without unnecessary battery usage. Sometimes people randomly tune in the frequencies that are not accurate enough and may lead to car radio draining your battery without you knowing.
Most people love to tune in to the radio now and then to give their favorite song a listen. The great news is that most modern cars allow you to do this without starting the car’s engine. So, you can always try turning your engine off when you do not need to drive but continue with your car radios. This method will allow the car’s alternator to come to a halt and will keep the car battery running for longer.
There are times you may think that the car’s radio is off but it may be using the battery in the background. Thus, when turning your radio completely off, locate the fuse that helps alter the radio’s buttons. Pull that fuse to stop the radio from causing battery drains. When you want to continue with your resumed radio sessions, all you need to do is toggle the switch back on.
Frequently Asked Questions (FAQs)
There are several questions that people often have in mind regarding the car battery drain and using a radio system for less power consumption. Thus, we have compiled a few radio and car battery queries to help you get a better understanding. So, let us take a look below to find the answers to saving car battery power.
How can you deal with a drained battery?
If you have drained your car’s battery, you need to recharge it to keep going. To recharge your battery, you will need jumper cables or someone who has them for safely performing the steps. You may also borrow or ask someone to give you half or more of their battery charging to start your car.
Start by parking your car so that both of the hoods touch the other car’s hoods. Also, always ensure that the vehicles are turned completely off before attempting to do this. You can check this by engaging the parking brakes on both vehicles. Next, locate the terminals of the batteries and clump the positive terminal to the positive terminal and the negative one to the negative end. The positive terminal usually has a ‘+’ sign on it or is colored red while the black color indicates a negative one.
When done, restart your car’s engine and let it recharge for a while. If you are unable to succeed in starting the car’s engine, check the cable plugs are clamped properly and retry. If you hear the engine starting, try to keep it running for a while.
Another method is to drive your car around the charging car to help it recharge faster for fifteen minutes or more. However, it might become a problem if you lose your battery in the middle of the night or at a place where there is no one around.
How long will a car battery last with the radio on?
A car battery will easily last for a few hours with your radio on. However, we cannot give an exact estimate since it depends on the type of radio system installed in your vehicle. Also, with additional gadgets installed like a subwoofer the battery life may be reduced by a significant amount.
For instance, if your car’s battery lasts four to six hours with the radio on then adding a subwoofer will shorten it to two hours. However, if you wish to make your battery life last longer, try turning on the accessory mode, which is often called the ACC mode. It works like a power-saving mode and helps turn off unnecessary battery consumption.
How to keep the radio on when a car is off?
When you want to keep the radio on but turn your car’s engine off, always ensure that the gear is in a neutral position. Then, you can turn your car engine off to avoid unnecessary battery consumption. The same is applicable when you switch to the accessory mode. To do this, pull your foot away from the brake pedal and press the car’s start button. This will allow you to switch to the ACC mode automatically.
Now you can easily enjoy and groove to your favorite music without turning the engine on. To turn the car back to its previous state, press the start button again to switch off the radio. However, for later car models, especially those after the year 2012, there are a few different steps that you might need to follow to achieve this.
Start by taking your foot away from the brake pedal. Here, you will have an e-brake option for switching to the ‘Park’ mode. Turn it on. Next, change your gear back to neutral to prevent the car from moving.
Press the button ‘Stop’ and take your foot away from the brake pedal simultaneously. Doing this will take your car to accessory mode. So, you can enjoy your beats without keeping the engine running. To turn the radio off, repeat the process of taking your foot off the brake pedal.
Wrapping It Up
We all love playing music whenever traveling from one place to another. However, sometimes this may lead to complete drainage of your car battery, even worse, radio draining car battery when off. That may or may not be the fault of your car’s radio.
