How to Replace the Battery in an ETC Device?
2 Answers
Method for replacing the battery in an ETC device: 1. Open the shell of the ETC device until you see the internal green motherboard; 2. Use a soldering iron to melt the solder on the old battery, then remove the old battery; 3. Solder the new battery into the battery slot, restart the ETC device after installation, insert the ETC card, and the displayed content upon startup indicates successful installation. Method for installing an ETC device: Unpack the ETC device, take out the OBU electronic tag, clean the installation area (usually located at the top of the vehicle's front windshield), peel off the adhesive backing film, find the attachment position, and press firmly to secure it. Currently, ETC devices come in two power supply modes: one uses solar panel charging, and the other uses wired charging.
I've had an ETC device for several years, and when the battery died, I replaced it myself. First, you need to confirm whether your ETC model has a replaceable battery compartment, such as a small cover on the back. Use a Phillips screwdriver to gently loosen the screws, being careful not to apply too much force to avoid damaging the device. When removing the old battery, be cautious not to touch the circuit board to prevent static electricity. Replace it with a new battery of the same model, typically a CR2032 or similar coin cell. After installation, power it on to test if it works properly. If the ETC is still under warranty, self-repair might void it, so be careful about this. Parking your car in the sun more often to let it charge can help extend its lifespan. If you encounter issues, check the manual or consult the issuing bank first, but if you're handy, this task isn't difficult.
