First of all, we do not have a careful calculation and clear understanding of the selected battery capacity and the effective capacity of the circuit board designed and selected by ourselves. At present, the batteries we choose (whether CR18505S/M or ER18505S/M) are lack of intelligent water meter (mainly IC card prepaid water meter) to support the normal work of 6. + For one year (usually only two to three years), it's just that people are greedy for cheap batteries. Some people argue that some of the batteries they use are still okay after eight years. We would like to ask these manufacturers, how do you know that the batteries have been working normally for eight years (90% of the batteries are still working in the absence of lithium-argon batteries for more than 10 years)? At the same time, why not think about why a large number of batteries can only be used for two to three years?

另外，国外对电池的在线检测工艺和办法在我国鲜有厂家控制（譬如无损伤检测电池性能的工艺和办法我国目前不论是电池消费厂或运用单位都还没有）。各位又试想一下，诸位的智能水表从设计到消费，其工艺又有几细节还需求完善（还不是急功近利地向市场投放不完善以至存在致命缺陷的产品）？
