Hello, my electronic calendar clock is out of time. I took it apart and looked at it. There is a 3v battery in it.
The time display of the digital perpetual calendar electronic clock has nothing to do with the 3V battery inside.
This 3V battery is just a memory battery, not a power battery.
The main reasons for this situation are:
The power supply is partially disconnected, otherwise the power supply line is disconnected or the transformer is burnt out;
The time control chip is broken, which will also cause the digital calendar time to be unable to display.
It is best to remove the circuit board from the digital calendar and return it to the original manufacturer.
