How to Replace the Battery When the ETC Runs Out of Power?

When the ETC runs out of power, go to an ETC service outlet to replace it. The vehicle owner needs to replace the OBU device, and this replacement is free of charge. The owner can remove their ETC OBU device and go to the ETC direct service point in their city to complete the free replacement procedure. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply, the vehicle owner must provide the original and photocopy of their valid ID card and vehicle registration certificate. If the application is not made by the owner themselves, the agent must also bring their valid ID card. The photocopy of the vehicle registration certificate must include the page stamped with the most recent annual inspection. Additionally, a bank card for deducting highway tolls is required. Applicants must be between 18 and 60 years old, and the vehicle must be registered under an individual's name. Documents required for company vehicles: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle registration certificate; and the vehicle for which ETC is to be applied. How ETC works: The vehicle-mounted electronic tag installed on the windshield communicates with the microwave antenna in the ETC lane at the toll station. Using computer networking technology, the system settles accounts with the bank in the background, allowing vehicles to pay highway or bridge tolls without stopping when passing through toll stations. Benefits of installing ETC: Saves time: eliminates the hassle of waiting in line; Green and eco-friendly: reduces noise and exhaust emissions by allowing vehicles to pass through toll stations without stopping; Reduces wear and tear: lowers costs by reducing the frequency of vehicle starts and stops, minimizing wear and fuel consumption, and users can enjoy toll discounts; Improves efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
As a hands-on young car owner, I once tried replacing the ETC battery myself when it died, only to end up locking the device and wasting a lot of time. The steps are: First, gently pry open the ETC device cover with a small screwdriver, being careful not to touch the anti-tamper mechanism, which triggers protection. Inside, the battery is usually a CR2032 coin type—just replace the old one with a new one of the same model. But here’s the catch: opening the device may automatically lock it, requiring a trip to the service center for reactivation. Now, I always advise friends to skip the DIY hassle and head straight to an official ETC service center, where experts handle it with proper tools, often for free or at a minimal cost. While driving, regularly check your ETC’s response speed—batteries typically last 2-3 years, and avoiding prolonged high-temperature parking can extend their lifespan. Bottom line: DIY might be thrilling, but the risks outweigh the rewards. Leave it to the pros for peace of mind and safety.
