The battery shall be kept in a dry place. It should not show any dew point when stored in this condition. : This shall be measured with the instrument described in Item 9.2 v). |
- Precautions for use
- A battery shall not be stored at temperatures in excess of 45℃. Storage at less than 30℃ is recommended. Storage at less than -30℃ can deform the plastic parts and may cause a leakage. To prevent self-discharge caused by corrosion, or decrease of insulation, humidity during storage shall be less than 70%.
- The battery has an explosion resistant construction. But the following cautions should be taken. because combustible materials such as lithium metal and organic electrolyte are contained in the battery.
* Do not short circuit.
* Do not dispose in fire.
* Do not charge.
* Do not disassemble.
- Keep away from heat sourse of flame.
- The battery shall not be washed by ultrasonic wave washer.
