Steps to remove the ETC battery: 1. Take out the ETC card and open the device to see the display inside; 2. Use a soldering iron to melt the solder on the old battery and remove it; 3. Replace it with a new battery, apply some solder, and solder the new battery in place; 3. After soldering both batteries, locate the restart or reset switch and reboot the device; 4. Reassemble the casing and reinsert the ETC card. ETC (Electronic Toll Collection) is a dedicated road toll system, commonly used on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion.
As a seasoned driver with over a decade of experience, I was once curious about how to remove the battery from an ETC device, since batteries degrade over time and can cause the device to malfunction. First, it's important to note that the battery in an ETC device is typically built-in and not designed for user removal. Tampering with it can damage the entire device or even trigger the vehicle's alarm. The most crucial step in the process is to turn off the car's ignition to cut power, then gently pry open the plastic clips to remove the ETC card—being careful not to scratch the windshield or internal wiring. If you want to inspect the internal battery, you'll need a miniature screwdriver to unscrew the casing, but this carries significant risks: if the battery leaks or short-circuits, it could not only damage the device but also affect the vehicle's electronic systems. Therefore, I strongly advise against attempting this yourself. Instead, contact your ETC service provider or visit a professional repair shop. They can safely replace or refurbish the device, saving you time and effort while ensuring road safety. Regularly checking your ETC device's status while driving can help prevent sudden malfunctions.
As an electronics repair enthusiast, I've attempted to disassemble ETC batteries several times and have summarized a simple process: First, prepare tools like plastic pry tools and miniature screwdrivers. During operation, turn off the engine and remove the ETC card, then gently pry open the clip fastening points, but be mindful of the varying installation positions across different car models—some are discreetly stuck in the corner of the windshield. After opening the casing, the battery is hidden next to the circuit board, typically a button-type lithium battery. You can remove it by disconnecting the wires, but be cautious of static electricity to avoid burning out the chip. My personal experience is that this task requires patience: the casing is thin and fragile, and excessive force might break it; after replacing the battery, test whether the device charges properly, otherwise, ETC failure could affect highway travel. While DIY is fun, beginners should first consult service manuals or watch video tutorials to avoid accidental damage. Actually, ETC batteries can last five to six years, and when they fail, it's advisable to replace the entire unit to save the hassle of repeated disassembly.
