How Long Does an ETC Lithium Battery Last?
2 Answers
Generally, the battery in an ETC device can last for about 3 years under normal usage. For solar-powered ETC devices that are not frequently used, it is recommended to charge them every 3 months to prevent natural discharge of the internal battery. ETC devices have an internal battery and are charged externally via solar power, so they do not require regular charging. ETC stands for Electronic Toll Collection, which is an electronic toll system. To apply for an ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent must also present their valid ID card. The photocopy of the vehicle registration certificate 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 a personal name. For company vehicles, the required documents include: A letter of introduction from the vehicle owner (with official seal); a photocopy of the organization code certificate or business license (with official seal); the agent's original ID card; the original vehicle registration certificate; and the vehicle for which the ETC is to be installed. How ETC works: The system uses an onboard electronic tag installed on the vehicle's windshield to communicate with microwave antennas in the ETC lanes at toll stations. It employs computer networking technology to settle transactions with banks in the background, allowing vehicles to pay highway or bridge tolls without stopping. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass through toll stations without stopping; Cost-saving: Reduces wear and tear and fuel consumption by minimizing vehicle starts and stops, and users can enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC systems faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
As a car owner and tech enthusiast, I often research in-car devices, including the lifespan of ETC lithium batteries. These typically last 3 to 7 years, depending on usage habits and environment. Lithium battery lifespan is determined by charge-discharge cycles and quality grade. With frequent highway use or exposure to extreme temperatures like summer sun exposure, the lifespan may shorten to just 2 years before failure. Performance degrades over time - for instance, the ETC responds sluggishly when power is low, potentially causing scanning failures at toll gates. I recommend proactively checking device status every 2-3 years by observing indicator light blinking or using the companion app to check remaining battery. Replace batteries promptly if issues arise to avoid travel inconveniences. On average, replacement costs just a few dozen yuan, but proper maintenance ensures efficient ETC operation and enhances driving convenience.
