Why do some small household appliances say that alkaline batteries such as Fu Nan or Duracell cannot be used?

I believe some parents and friends have been troubled by the saying that toys can't use Fu Nan batteries. So many years of old brands and hundreds of millions of users, why did such negative news suddenly come out? Do Fu Nan batteries really have quality problems as rumored?

In fact, the argument that toys can't use Fu Nan batteries is actually very one-sided and unfounded, misleading consumers to some extent. From a scientific point of view, the cause of the incident is not the quality problem of Fu Nan battery, but the quality of the toy itself is not up to standard. For a long time, Fu Nan has been favored by consumers because of its abundant electricity, reliability and durability. The image of "one paragraph is better than six paragraphs" has been deeply rooted in people's hearts. This is mainly because Fu Nan is an alkaline battery, while other brands of products on the market are more carbon batteries. In fact, the performance of the two is very different. Carbon batteries are weak, and they are weak quickly. Used in toys with poor conductivity and thin wires, it just covers up the quality problems of toys.

There are many inferior products in the market, including some toy products, which do not meet the relevant quality system certification. Some products cut corners to reduce the original resistance; Some children's toys are shoddy and use coils that are lower than the quality requirements. This means that the toy itself has a huge safety hazard. When inferior toys use stable batteries, because the batteries can provide stable and lasting current, the toys are burnt out after working continuously for a period of time. In contrast, carbon battery is more suitable for this "fragile" inferior toy product because of its fast voltage drop. However, toys are often accompanied by children's growth process, so parents and friends are advised to pay attention to the safety of toys and choose high-quality toys such as high-quality batteries and Fu Nan batteries to give children a safe and happy childhood.
