Button battery has the advantages of small size, light weight, easy replacement and high energy density. In addition, button cell usually has a long shelf life, so it is not easy to leak liquid at night, which may be more suitable for some long-term random rear switches.
However, using button cell's convenient switch may require a more complicated manufacturing process, because it needs to fix the battery in the correct position. In addition, the price of button batteries is relatively high, which may increase the production cost.
As a traditional power supply, dry battery has the advantages of convenient purchase and relatively low price. For some random switches with short service time, dry battery may be a more economical choice. In addition, dry batteries can be seen everywhere in the market, so some users may get dry batteries more easily.
However, the disadvantage of dry batteries is that their service life is relatively short and they may need to be replaced more frequently. In addition, if the dry battery is not properly treated and recycled, it may cause pollution to the environment.
To sum up, button cell may be a better choice for post-it switches that need to be used for a long time. However, for switches with short service time, dry batteries may be more economical. Which battery to choose depends on your specific needs and preferences.
