How long can an ETC last on a full charge?

Generally, an ETC can last 2-3 months on a single charge. The ETC user manual does not specify how long an ETC can last on a single charge. For vehicle owners who do not use ETC frequently, it is recommended to charge the ETC device every 3 months. If the ETC is powered by a wired connection and is not used for a long time, it is recommended to charge it once a month to avoid affecting the battery life due to self-discharge. ETC is the abbreviation of Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, you need to provide the original and photocopy of the vehicle owner's valid ID card and driving license. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the driving license should include the page with the most recent annual inspection stamp; a bank card for deducting highway tolls; the applicant must be between 18 and 60 years old; the vehicle must be registered under the applicant's name. Documents required for a company vehicle: 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 driving license of the vehicle; the vehicle that needs to apply for ETC. How ETC works: Through the on-board electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane of the toll station, and uses computer networking technology to settle accounts with the bank in the background, allowing the vehicle to pay highway or bridge tolls without stopping when passing through the toll station. Benefits of installing ETC: Save time: Avoid the hassle of queuing and waiting; Green and environmentally friendly: Green and low-carbon, vehicles passing through the toll station without stopping can reduce noise and exhaust emissions and pollution; Save wear and tear: Save costs, reduce the frequency of vehicle starting and braking, reduce wear and fuel consumption, users can enjoy toll discounts; Improve efficiency: The ETC lane's passing efficiency can theoretically be increased by 2-3 times or more, making the traditional ETC updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
I've checked the information about ETC devices, and their batteries are usually lithium-based with very low power consumption. A full charge can last 6 to 12 months, depending on usage. For someone like me who frequently uses highways and passes through toll stations several times daily, the battery drains faster and may require recharging every 3 to 6 months. But if you only occasionally go out for a drive, a single charge can last nearly a year. Some ETC devices come with solar charging functionality, which automatically replenishes power during normal use, extending the battery life even further. The one installed in my own car has this feature, and it's been showing a green light for over a year now. It's important to regularly check the battery indicator light: a steady green light means normal operation, but if it starts blinking or turns red, recharge it immediately, or the toll gate might not lift. So ETC devices are thoughtfully designed to minimize frequent charging concerns, making them ideal for busy car owners.
As a long-term ETC user, I must say this thing is super energy-efficient! A single charge lasts for over half a year to a full year. With my daily highway commute, one charge typically sustains around 8 months. For city driving with less highway usage, it lasts even longer—easily hitting the one-year mark. The solar-powered ETC version is even more reliable, charging while in use with minimal manual intervention. My advice is to choose the installation spot carefully, ensuring it gets sunlight when parked. Don't worry about the battery—ETC is designed for convenience. New users shouldn't panic; just recharge when the red light comes on. In short, its battery life is solid, adding minimal hassle to daily driving.
