How Long Does an ETC Charge Last?
2 Answers
A single charge for an ETC device typically lasts 2-3 months. The ETC user manual does not specify the duration of a single charge. For vehicle owners who do not frequently use ETC, it is recommended to charge the ETC device every 3 months. For wired power-supplied ETC devices, if they are not used for an extended period, it is advisable to charge them once a month to prevent battery lifespan reduction due to self-discharge. ETC stands for Electronic Toll Collection, which refers to the electronic toll system. To apply for an ETC, the vehicle owner must provide original and photocopied versions of their valid ID card and vehicle license. If the application is handled by a proxy, the proxy'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 their name. How ETC works: The vehicle-mounted electronic tag, installed on the windshield, communicates with the microwave antenna in the ETC lane at toll stations. Using computer networking technology, it settles payments with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Promotes low-carbon travel by reducing noise, exhaust emissions, and pollution as vehicles pass through toll stations without stopping; Cost-saving: Reduces vehicle startup and braking frequency, minimizing wear and fuel consumption. Users can also enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC systems more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
My ETC device lasts quite a while on a single charge. As an experienced driver who doesn't frequently use highways, my OBU battery can last about one and a half to two years. The lithium battery automatically enters sleep mode when parked to conserve power. However, if you commute through toll stations daily, the battery might alert you for recharge in less than a year. Factors affecting battery life include weather - it drains faster in hot summers, while cold winters may reduce its endurance. Charging is convenient; just use the original charger or visit a service station. My last charge was in late 2022, and it didn't remind me to recharge until April this year, averaging over ten toll transactions per full charge. Storing the device in shaded areas away from direct sunlight can help extend its lifespan.
