## **Storage** 

- l The storage area should be clean, cool _(preferably not exceeding + 30°C),_ dry and ventilated. 

## **Warning** 

- l Fire, explosion and burn hazard. 

- l Do not recharge, short circuit, crush, disassemble, heat above 100°C _(212°F),_ incinerate, or expose contents to water. 

- l Do not solder directly to the cell _(use tabbed cell versions instead)._
