1 month: -20~60°C - Note (*¹): Protection function of the battery pack should be set within the specified charge, discharge and temperature range in Cell Specification.
Note (*2): Discharge OTP(over temp. protection) should not be over 70°C of Cell surface
temperature. Protection set should be based on the location of Cell surface with the highest temp increase part of the battery pack
Note (*3): If Cell is kept as ex-factory status (30% of charge), the capacity recovery rate shall be more than 80%.
Warnings:
- Do not connect battery directly to cigarette/aux jack in automobiles. Use only approved chargers.
- Do not charge with constant current more than maximum charge current.
- Do not charge the cell, which was discharged equal to 1V or under.
- Do not disassemble or reconstruct the battery.
- Do not throw or cause impact.
- Do not pierce a hole in the battery with sharp things. (such as nail, knife, pencil, drill)
- Do not use with other batteries or cells.
- Do not solder on battery directly.
- Do not press the battery with overload in manufacturing process, especially ultrasonic welding.
- Do not use old and new cells together for packing.
- Do not expose the battery to high heat. (such as fire)
- Do not put the battery into a microwave or high pressure container.
- Do not use the battery reversed.
- Do not connect positive(+) and negative(-) with conductive materials (such as metal, wire)
- Do not allow the battery to be immersed in or wet with water or sea-water.
- Do not give immoderate heat and force to battery cell during a welding process of metal plates on it.
