Do not modify or disassemble: Lithium batteries have a complex internal structure. Disassembly by non-professionals may cause short circuits, explosions, or poisoning (such as electrolyte leakage). If the battery is damaged, contact a professional recycling organization for disposal.
Keep away from fire and high temperatures: Lithium batteries may decompose and produce flammable gases at high temperatures, which may explode upon contact with open flames or electrical sparks. Keep away from fire, heat sources, and direct sunlight during use and storage.
Regularly inspect the appearance: If the battery shows signs of bulging, leakage, deformation, or unusual odor, stop using it immediately and replace it. These phenomena may be signs of internal battery failure, and continued use may lead to safety accidents.
