Enough insulation layers between wiring and the cells shall be used to maintain extra safety protection.
Never incinerate nor dispose the cells in fire. These may cause firing of the cells, which is very dangerous and is prohibited.
The cells shall never be soaked with liquids such as water, seawater, drinks (soft drinks, juices, coffee, etc.).
The battery replacement shall be done only by either the cells supplier or device supplier, and never be done by the user.
The cells might be damaged during shipping by shock. If any abnormal features are found (damage in plastic envelope, deformation of the package, smelling of electrolyte, electrolyte leakage), the cells shall never be used. Keep leaky or smelly batteries away from fire to avoid firing.
