PRECAUTIONS FOR HANDLING SEALED LEAD-ACID BATTERIES - CONTINUED

8. Storage

CAUTION

  • (1)

    Store the batteries in a fixed position separate from metal or other conductive materials.

  • (2)

    Keep the batteries from rain water that could cause corrosion on the terminals of the batteries.

  • (3)

    Keep the batteries right-side-up during transportation and do not give any abnormally strong shock and jolt to the batteries. Transporting the batteries in an abnormal position or handling them roughly could destroy the batteries or cause their characteristics to deteriorate.

  • (4)

    When storing the batteries, be sure to remove them from the equipment or disconnect them from the charger and the load, then store them at room temperature or lower temperature. Do not store the batteries at direct sunlight, higher temperature or high humidity. To do so cause the batteries short life, performance deterioration or corrosion on terminals.

9. Disposal and Recycling

CAUTION

  • (1)

    Please write the information about battery recycling on the equipment, the package, the carton, the instruction manual etc. in countries where legal or voluntary regulations on battery recycling are applicable.

  • (2)

    Design the equipment such that exchange and disposal of the batteries can be undertaken easily.

REQUEST

  • (1)

    Charge the batteries at least once every six months if they are stored at 25°C. Use the charge method specified in "3. Preparation Prior to Use". The interval of this charge should be reduced to 50% by each 10°C rise in temperature above 25°C. The self-discharge rate doubles for each 10°C in temperature. If they are stored for a long time in a discharged state, their capacity may not recover even after charge. If the batteries are stored for more than a year at room temperature, the life of the batteries may be shortened.

  • (2)

    Store the batteries starting from the fully charged state to prevent the life of the batteries being shortened.

(3) Use the batteries as quickly as possible after receiving them as they gradually deteriorate even under proper storage conditions.

(3) Used batteries should be recycled. When returning used batteries, insulate their terminals using adhesive tape, etc. Even used batteries still have electrical charge and an explosion or a fire may occur, if proper insulation is not given on the terminals of the used batteries.
