Generally, an ETC device can last 2-3 months after a single charge. The ETC user manual does not specify how long an ETC device can last after being charged. For car owners who do not frequently use ETC, it is recommended to charge the ETC device every 3 months. If you are using a wired-powered ETC and do not use it for a long time, it is recommended to charge it once a month to avoid affecting the battery life due to self-discharge. There is also a solar-powered version of ETC, which does not require deliberate charging if used frequently. ETC is the abbreviation for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle license. If the application is not made by the vehicle owner, the agent's valid ID card is also required. The photocopy of the vehicle license should include the page with the most recent annual inspection stamp. 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-owned 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 license; the vehicle for which ETC is to be applied. Benefits of installing ETC: Time-saving: Avoid the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions; Cost-saving: Reduce vehicle startup and braking frequency, minimizing wear and fuel consumption. Users can also enjoy toll discounts; Efficiency improvement: ETC lanes can theoretically improve 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. Precautions for installing ETC: Do not obstruct the view. It is best to install it behind the rearview mirror: Many car models have a large rearward tilt angle on the windshield, which reduces the driver's field of vision. If ETC is installed without considering this, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After installation, the windshield will press the anti-removal lever in. If removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Notes for using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters to avoid automatic toll payment for the vehicle in front. The recognition speed for ETC lanes is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle's device information, leading to toll deduction failure. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failure.
