Maintenance of batteries and electronic components: Some
full size sex dolls have batteries and electronic components, and
US sex dolls also have applications in this regard. For batteries, charge and use according to the battery type and manufacturer's instructions. Avoid overcharging or over-discharging. If the doll is not used for a long time, the battery should be charged to about 50%, and then taken out for storage. The battery should be charged and discharged for maintenance every once in a while. For electronic components, such as sound-generating devices and heating elements, water should be prevented from entering and use should be avoided in humid environments. Regularly check whether the connection of electronic components is loose and whether the function is normal. By properly maintaining the battery and electronic components, the functionality of the full size sex doll is not affected.
