Warning
Fire, explosion and burn hazard.
Do not recharge, short circuit, crush, disassemble, heat above
100 °C (212 °F), incinerate, or expose contents to water
Storage
The storage area should be clean, cool (preferably not
exceeding +30 °C), dry and ventilated
Warning! Keep batteries away from children!
Always keep your batteries away from children to prevent
swallowing. If ingestion does occur, however, be aware
that initial symptoms may be similar to other childhood
illnesses such as coughing, drooling and discomfort.
