5. Method of Handling and Operation DANGER

(1) Do not directly connect the positive and negative terminals with a conductive material such as a wire. Be careful while using a metal tool such as a wrench and/or carrying the batteries with metallic necklaces and hairpins not to make a short circuit. A short of the battery's terminals may cause heat generation, an explosion or a fire.


  • (1)

    Never dispose of the batteries in a fire as it may cause them to explode or generate a toxic gas.

  • (2)

    Do not attempt to disassemble the batteries as it could cause leakage of sulfuric acid that could bodily injure.


  • (1)

    To prevent accidents from happening, change any battery that is found to have an abnormality such as a crack, a deformity, or leakage. The batteries must be kept clean and free from dust to prevent loss of capacity or accident.

  • (2)

    If any abnormality of the charge voltage or the discharge voltage is detected replace the batteries with new ones.

  • (3)

    Charging the batteries with an inverse polarity connection between the batteries and the charger could cause electrolyte leakage, heat generation, or a fire.

  • (4)

    Do not solder directly on the batteries' terminal tabs. Soldering directly on the batteries' terminals may cause a leak of electrolyte. Consult Panasonic when soldering is necessary.

  • (5)

    Avoid the use of the batteries differing in capacity, type, history of use (charge/discharge operation). These differences could cause electrolyte leakage or heat generation.

  • (6)

    Do not remove or scratch the outer tube of the battery or it may cause an electrolyte leakage or electrical leakage.

  • (7)

    Do not allow the batteries to be subjected to any strong physical shocks or jolts while moving them. Treating the batteries roughly could cause leaks, heat generation, or a explosions.

  • (8)

    Do not charge the batteries beyond the amount of the time indicated in the specifications, or do not charge after the charge indication lamp indicates a full charge. Take the batteries off the charger if the charge is not finished after the specified charge time. Over-charging can cause leakage, heat generation, or explosions.

  • (9)

    Children should be taught how to handle and use the batteries correctly.

  • (10)

    Keep the batteries out of the reach of small children at all times.
