How often should ETC be charged?
3 Answers
ETC devices come in two types: wired charging and solar panel charging. Solar-powered ETC devices do not require charging, while wired charging ETC devices need to be charged using a charger. Generally, an ETC device can last 2-3 months on a single charge. Both types of ETC electronic tags have internal batteries. Solar-powered ETC devices do not require charging during daily driving, and their lithium batteries can last up to 3 years under normal use. However, for those who do not use ETC frequently, it is recommended to charge the ETC device every 3 months to effectively mitigate the impact of natural battery discharge on its lifespan. ETC stands 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 and vehicle registration certificate. If the application is not made by the owner, a valid ID of the agent is also required. 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, and the applicant must be between 18 and 60 years old, with the vehicle registered under their name. How ETC works: Through the onboard electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane at toll stations. Using computer networking technology, it settles transactions with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay tolls. 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 wear and fuel consumption by minimizing the frequency of starting and braking, and users can enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
I've been driving on highways for seven or eight years and have never encountered a charging issue with my ETC. Its battery is designed to be highly durable, typically lasting five to seven years without needing a charge. For example, my ETC has been in use for five years, and the indicator light still shows a steady green. Some solar-powered versions are even more long-lasting, as they recharge automatically without any intervention. If the battery runs out, a red light will flash or the device will beep, prompting you to replace it at a service point. When driving, I make it a habit to keep the windshield clear of any obstructions, ensuring the ETC has an unobstructed position for stable signals and quick passage through toll stations. I recommend checking the device's indicator light briefly each month—as long as it's green, you can drive with peace of mind. Overall, ETC is incredibly convenient, significantly reducing the risk of long queues on highways.
A mechanic friend told me that ETC devices have built-in lithium-thionyl chloride batteries, whose low-power characteristics allow them to last five or six years without charging. There's basically no need for charging since most are sealed and non-rechargeable. If you really want a rechargeable version, like some older models, they typically need a full charge every one or two years. From my experience, ETC batteries are greatly affected by temperature. In summer, try to park in a garage to avoid high temperatures and prevent accelerated aging. When the battery dies, you might get stuck at toll gates, causing inconvenience. So, every six months or so, I manually press the device's test button to confirm it responds normally, ensuring efficient and safe driving. Charging isn't the focus; the key is regular inspection and maintenance.
