Lithium-ion batteries power many modern sex dolls, and their safety hinges on sensible charging practices. Always use the charger and connectors specified for the doll, or a compatible unit recommended by the manufacturer. Incompatible chargers can deliver incorrect voltage or current, leading to overheating, swelling, or, in worst cases, fire risk. Never attempt DIY fixes on damaged battery packs, and replace a damaged battery promptly through a qualified service provider.
Charging habits matter as much as the charger. Do not leave batteries charging unattended for long periods, especially overnight. If a battery becomes unusually warm, emits a strange odor, or swells, disconnect immediately and seek professional guidance. In cold climates such as Finland’s winter, battery performance may drop and charging efficiency can slow; avoid exposing the battery to extreme cold. When storing the doll for extended periods, aim to keep the battery at a moderate level, roughly 40-70%, and check the charge every few weeks.
Keep battery connections clean by gently wiping connectors with a dry microfiber cloth before plugging in. Protect cables from physical damage and avoid pinching or bending them harshly. Store the doll and its charging setup in a dry, well-ventilated area away from heat sources or moisture. For long-term safety, arrange periodic professional maintenance checks, and never attempt to bypass safety features or modify the battery system.
