How to Replace the Battery in an ETC Device?
3 Answers
ETC devices do not require battery replacement. Simply drive to your local ETC customer service center to get a new ETC device. Here is some information about ETC: 1. The process of replacing an ETC device is very simple. Just bring your ID card, vehicle registration certificate, vehicle information card, and the depleted ETC device to the customer service center. Exchange your documents for a new ETC device, and the staff will install it for you. 2. Due to the convenience of ETC (Electronic Toll Collection) systems, which allow for highway toll payment without stopping, and even some parking lots now use ETC for payment, more and more car owners are installing ETC devices. 3. To check if your ETC device is out of battery, remove the ETC card and reinsert it into the device. If the device does not emit a 'beep' sound, it is likely out of power. Generally, ETC devices may experience this issue after about 2 years of use.
I just replaced the battery in my car's ETC device myself yesterday, and it was actually quite simple. First, find a small screwdriver and carefully remove the ETC device from the windshield—it's usually secured with clips. Then, check the back of the device for a removable cover; unscrew it to access the battery compartment. Most ETC devices use a CR2032 coin cell battery. When replacing the battery, make sure not to reverse the polarity, as this could damage the circuit. After replacing, reassemble the device and press the power button to test if it works properly. If you're not confident in doing it yourself, it's best to take the device to a roadside repair shop for assistance—spending a little money can save you hassle. Pay attention to the battery lifespan while driving; typically, it needs replacement every two years or so. Otherwise, failure to recognize the device at highway toll stations may affect your travel efficiency. Additionally, some newer ETC models are rechargeable and don’t require battery replacement—just check the manual when purchasing.
Be cautious when replacing the ETC battery. First, park the vehicle in a safe location and turn off the engine to avoid accidents. Gently remove the ETC device without applying excessive force to prevent damaging the adhesive. Locate the battery compartment cover, which usually has a small clip to open it. Inside, you'll find a CR2450 or CR2032 battery type—remember the model before purchasing the same one at the store. When installing the new battery, ensure the electrode orientation matches, securely insert it, and then close the cover. Don’t forget to test the functionality, such as entering the highway to check automatic recognition. If any abnormalities occur, stop immediately and seek professional repair services, as improper handling may cause failure or malfunctions. It's recommended to check the battery indicator light every six months to avoid travel inconveniences.
