PRECAUTIONS

Li-Ion cells can be very dangerous if misused. Each cell or battery pack must have a PCM circuit installed before use. Improper use or short-circuiting can cause fire or explosion. Use cells according to the parameters contained in the manufacturer's datasheet. ❌Do not short-circuit cells, e.g., by putting them in a pocket with keys. ❌Do not insert cells into equipment or chargers in reverse polarity. ❌Do not overcharge or excessively discharge. ❌Do not use modified or damaged chargers. ❌Do not leave cells in the charger for more than 12 hours. ❌Do not expose to water and high temperatures. ❌Do not use if the cell has damaged insulation. ❌Do not expose cells to fire. ❌Avoid vibration and excessive pressure. ❌Do not disassemble or deform cells. ❌Do not solder. Store out of reach of children. In a protective case in a cool, dry place. Dispose of used cells according to local regulations.
