Can be used on the gas meter, but the gas meter is very power-saving rechargeable battery is not practical, the human gas list is generally two or three years only a battery, but the rechargeable battery is charged after a few months.
1, plug-in gas meter, no low voltage protection mechanism, will not be forced to work when the voltage is lower than 1.35V, you can use nickel-metal hydride rechargeable battery;
2, the plug-in gas meter, there is a low voltage protection mechanism, the reason may be afraid of insufficient power of the old battery leakage corrosion gas meter, it may not be able to use nickel-metal hydride rechargeable battery;
3, wireless meter reading charging type smart gas meter, large power consumption, can not use 1.2V nickel-metal hydride rechargeable battery.
The gas meter cannot use rechargeable batteries. Because the usual use is a dry battery, the voltage is 1.5V, and the rechargeable battery voltage is 1.2V does not meet the conditions, so you can not use rechargeable batteries.
It is recommended to buy a better dry battery to replace the battery for the gas meter.
The replacement method is: there is a battery box under the table code, open the installation of a new battery on the line, there is no impact on the gas meter, but the gas meter may not go when the battery is changed, and it is good to change the battery
