Can you drive your car with a failed auxiliary battery?
Yes and no are the answers. In general, it’s not a brilliant idea to drive when something about the car doesn’t work, even if it isn’t serious. You don’t know how the problem will affect other parts of the vehicle or your safety.

The auxiliary battery is a secondary backup power source that can be used to start the engine in case of main battery failure. Its main responsibility is to run and power the vehicle’s additional accessories such as starter and lights. If something goes wrong with the main battery, there is a backup auxiliary battery that will kick in and keep the car running. This is not a complex system to manage, but nonetheless, it requires some attention, maintenance, and replacement at regular intervals of time for optimal performance.
If your auxiliary battery begins showing signs of something wrong with it (it can be slow cranking or dimming lights), you should immediately replace it before more damage is done to the car. If you ignore it, you risk further damage and even more inconvenience if your main battery fails for good and does not give enough power to start your vehicle’s engine.
How would you know if your car has an auxiliary battery?
If you are not sure or indefinite if your car has an auxiliary battery or not, you can check your owner’s manual for this information. If the car is a used one and it does not have an owner’s manual, some cars do come with a sticker on the inside of the driver door panel that provides descriptions about every part in the vehicle, including if there is an auxiliary battery installed.
Another option is to check the internet. There are many websites today with information on cars. You can simply search for your car’s make, model, and year to see whether it has an auxiliary battery or not. Or better yet, you can visit a local auto parts store or car dealership to seek for a more concrete answer. This way, you can also get to know more about the car’s auxiliary battery by asking for advice from professionals.
