Hello, I\u2019m Itsuki (@saigalog<\/a>), turning my whole home into a smart home with the SwitchBot series.<\/p>\n\n\n\n

Speaking of SwitchBot<\/mark><\/strong>, it is now well-known as a pioneer in IoT gadgets<\/strong>.<\/p>\n\n\n\n

While many can be USB charged or powered, some devices require alkaline or button batteries<\/strong>.<\/p>\n\n\n\n

When replacing batteries, many people probably wonder, “Which battery does this SwitchBot device use again\u2026<\/strong>“<\/p>\n\n\n\n

So in this article, I have summarized SwitchBot products that need battery replacement and their battery types<\/strong>, also serving as a reminder for myself who tends to forget.<\/p>\n\n\n\n
