With the advent of toll roads, the problem of controlling them arose. To solve this problem, checkpoints were established. During the holiday season, the number of cars in these areas increases, despite the fact that tolls are required. People have to wait in line for up to 15 minutes or more. But without thinking twice, specialists came up with a device called a transponder. It allows you to register a vehicle and debit money from the driver's account. You don't have to leave the car; simply tap the device against the reader through the window and continue driving.
Or you can install the gadget on the windshield, the reading will also happen.
How to replace batteries in a transponder?
Let's look at changing the battery using the example of the Avtodor device.
Take a regular knife and insert it into the slot between the top and bottom of the frame. Then, push the walls apart. The split needs to be made on all sides.
The battery in it is 3 volts.
To remove it, you need to disconnect the contacts from the positive and negative terminals. To do this, take a knife and use a rocking motion to remove the battery.
This method isn't very effective; if you have a soldering iron, try desoldering the contact with it. After that, get a new battery and solder everything back in.
But you don't have to replace the battery. To do this, locate the positive and negative terminals on the board and solder two wires to them. Solder the opposite ends of the wires to the USB connector. This is necessary to power the device from the USB port.
Thus, replacing the battery in the Avtodor transponder takes literally 10-15 minutes!
