PRECAUTIONS FOR HANDLING SEALED LEAD-ACID BATTERIES - CONTINUED

Safety Precautions

1. Environment and Condition DANGER

(1) Do not put the batteries into airtight containers or bags. The batteries tend to generate inflammable gas upon excess charge which may cause an explosion if enclosed in an airtight container.

WARNING

  • (1)

    The batteries must be charged using the specified charger or by maintaining the charging conditions indicated by Panasonic. If the batteries are charged under conditions other than those specified by Panasonic, they may leak, generate excessive heat, or explode.

  • (2)

    When using the batteries in medical equipment, incorporate a back-up system other than the main battery in the event of power failure.

  • (3)

    Insert insulation that is resistant to heat and sulfuric acid between the batteries and any metallic housing. Failure to do so may cause the batteries to smoke or burn in case of electrolyte leakage.

  • (4)

    Do not place the batteries near a device that may generate sparks (such as a switch or fuse) and do not place the batteries close to fire. The batteries may generate an inflammable gas when charged excessively that may ignite upon contact with a spark or they may burn or explode due to sparks or fire.

CAUTION

  • (1)

    Use or store the batteries in the temperature range specified below:

    • Discharge(operating an application): -15C~50°C.

    • Charged: 0C to 40C

    • Storage: -15C to 40C. Temperatures above or below those recommended could result in damage or deformity of the batteries.

  • (2)

    Avoid placing batteries near a heat-generating device (such as a transformer) which may cause the batteries to generate excessive heat, leak or explode.

  • (3)

    Do not allow the batteries to be exposed to rain or sea water. If the battery terminals should get wet, they may corrode.

  • (4)

    Do not use or store the batteries in a car under the blazing sun, in direct sunlight. To do so may cause the batteries to leak, generate excessive heat, or explode.

(5) Do not use or store the batteries in a dusty place as dust may cause them to short between their terminals. When using the batteries in a dusty place, check them periodically.
