The battery in Fu Nan, No.5, Section 4 of our natural gas meter has been dead for half a year. Is it normal?

Similarly, my hometown just used a gas cooker last winter, also four Fu Nan batteries, and stopped burning gas at the end of February. Then I looked at my watch. In April, it didn't show the numbers, but it died. When I use it next year, I'll just remove the battery and install a new one. Whether you are at home or not, whether you use it or not, the gas meter consumes electricity. Rural areas are mainly used for heating and combustion heating.
