1) Immediately discontinue use of the battery if, while using, charging, or storing the battery, the battery emits an unusual smell, feels hot, changes color, changes shape, or appears abnormal in any other way. Contact your sales location or Panasonic if any of these problems are observed.
(2) Do not place the batteries in microwave ovens, high-pressure containers, or on induction cookware.
(3) In the event that the battery leaks and the fluid gets into one’s eye, do not rub the eye. Rinse well with water and immediately seek medical care. If left untreated the battery fluid could cause damage to the eye.
(1) If the device is to be used by small children, the caregiver should explain the contents of the user’s manual to the children. The caregiver should provide adequate supervision to insure that the device is being used as explained in the user’s manual.
(2) When the battery is worn out, insulate the terminals with adhesive tape or similar materials before disposal.
Be sure to follow the rules listed below while charging the battery. Failure to do so may cause the battery to become hot, explode, or ignite and cause serious injury.

  • When charging the battery, either use a specified battery charger or otherwise insure that the battery charging conditions specified by Green Energy are met.
  • Do not attach the batteries to a power supply plug or directly to a car's cigarette lighter.
  • Do not place the batteries in or near fire, or into direct sunlight.
