Many smart locks use dry batteries instead of lithium-ion batteries. Why?

At present, smart locks have begun to enter thousands of households. Although they are not available in every household like TV air-conditioning, they can also be seen everywhere in some high-end residential areas, office buildings and apartment hotels. As we all know, nowadays mobile phones are powered by lithium-ion batteries, which can be reused, economical, energy-saving, and environmentally friendly. Many consumers have also discovered that most of the power supply methods used by smart locks are powered by AA alkaline dry batteries. Compared with dry batteries, the advantages of lithium-ion batteries are very clear: the energy density is large, more power can be stored in the same volume, there is no memory effect, the cycle charge and discharge cycles are up to 500 times, and the charging speed is fast. Other types of power supply batteries not only have high working voltage but also pollution, and their advantages in the power supply of smart locks are unclear. Since lithium-ion batteries have so many advantages, why do many smart lock manufacturers not use lithium-ion batteries for power supply, but still use dry batteries? First of all, lithium-ion batteries are easy to explode, and smart phones are powered by lithium-ion batteries. The explosion of mobile phone lithium-ion battery. In addition, power banks carrying high-power lithium-ion batteries are not allowed to be carried on the plane, also for safety reasons. From the perspective of fire safety, when a fire occurs, the lithium-ion battery will explode when exposed to high temperatures, which may cause the door to be locked and the door cannot be opened in time, which will bring greater trouble to rescue. Secondly, the charging problem of lithium-ion batteries is also very clear. Lithium-ion batteries can be charged, so it is necessary to consider the issue of charging. It is troublesome to use the power connection lock to supply power, and there is a danger of leakage. Also, lithium-ion batteries are not easy to buy on the market. Compared with AA batteries, lithium-ion batteries are very difficult for ordinary consumers to buy, while dry batteries can be bought in every grocery store, and the overturning range is wider. Dry batteries are relatively more stable. They have distinct advantages in terms of power supply for smart locks, so in general smart locks are powered by dry batteries. The above points determine that smart lock manufacturers can only use dry batteries for the time being. With the development of technology and technological progress, in the near future, batteries with longer battery life, better safety, and easier operation will soon be developed. Come out, by then we will be more comfortable and convenient when using smart locks, and we look forward to using cheap and easy-to-use new batteries in smart locks as soon as possible.
