Lithium battery built into the corrector for natural gas Roots meter and turbine meter

Do I have to use the manufacturer’s? Can I make one of the same specifications myself?
Are there also homemade lithium batteries? What does that mean? Typically, for safety reasons, flow meters equipped with lithium batteries use disposable lithium batteries that have overcurrent protection features and cannot be recharged. Such batteries ensure safe use in field environments. Therefore, it cannot be replaced with other types of lithium batteries of the same specifications; only lithium batteries of the same specifications and type can be used for replacement.
Some lithium batteries also have those types of connectors, with the electrodes held in place by plastic wires
Indeed, it’s not necessarily required to be from the manufacturer; one can also buy ones of the same specifications and type. If you have sufficient technical skills, you can buy a regular lithium battery with the same specifications and add protection functions yourself through DIY ； The concern is using ordinary lithium batteries of the same specifications directly, as a failure in the flow meter’s circuit board (or an accidental short circuit during operation) could lead to an accident.
Oh, is this what you mean by homemade? I guess so.
It is a flow meter that operates on battery power and has wires leading out from its battery terminals; when replacing the battery, these wires need to be disconnected, and then reconnected to the new battery using a soldering iron. Generally, there are no issues with identifying the positive and negative terminals. Of course, in practice, it’s basically not done by replacing it online. If you want to learn a skill, you have to give it a try; there’s a saying: “Those from Tsinghua and Peking University are not as good as those who are brave.” At worst, just burn it down and replace the circuit board – it costs a few hundred bucks: lol
1. For some natural gas flowmeters, it’s not possible to replace their (highly sophisticated) main circuit boards for just a few hundred dollars； 2. When gas flow meters are used in environments with very strict explosion-proof requirements (for example, when an intrinsically safe flow meter is required by the environment, but using another type of battery fails to meet those safety standards), the use of such batteries can pose safety risks and may lead to other accidents; it’s not just a matter of the meter getting damaged. So it’s safer to follow the requirements.
