First, the principle of energy gathering ring is equivalent to dust prevention. The principle of using energy gathering ring on Fu Nan battery is only adding a dust-proof film on the battery head, and there is not much technology involved. This kind of film is different from ordinary plastic film, which can block moisture and some dust in the outside air and ensure that the battery will not be short-circuited during use. In other words, put clothes on the battery at the gap at the bottom to prevent some dirty things from entering the battery and avoid short circuit, which will weaken the battery's power storage capacity.
Secondly, the energy gathering ring of Fu Nan battery has a certain commercial taste. In recent years, most of the advertisements about Fu Nan battery seen on TV are to highlight the energy gathering ring function of Fu Nan battery, and take this as the main function. However, the energy-gathering ring of Fu Nan battery is not the reason why Fu Nan battery is more durable than other batteries, but more is that the merchants have certain publicity color and certain rendering components in the promotion process. Therefore, it will bring the most intuitive feeling to consumers, that is, the energy gathering ring function of Fu Nan battery is very powerful. But what really locks the battery is the inside of the battery, and the role of the energy gathering ring is only dust prevention.
Third, the battery is locked inside. Generally speaking, Fu Nan battery is more durable among the batteries seen in the market. The fundamental reason is that there are some differences between Fu Nan battery and ordinary battery, and the most fundamental reason is that Fu Nan battery uses more electrode materials, and the process has also made some progress, which makes Fu Nan battery more durable. Coupled with the publicity and popularity of Fu Nan battery in advertising, it gives consumers the feeling that Fu Nan battery is more durable.
