instrument described in Item 9.2 v).

  1. 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.
