PRECAUTIONS FOR HANDLING SEALED LEAD-ACID BATTERIES - CONTINUED
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.
Never dispose of the batteries in a fire as it may cause them to explode or generate a toxic gas.
Do not attempt to disassemble the batteries as it could cause leakage of sulfuric acid that could bodily injure.
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.
If any abnormality of the charge voltage or the discharge voltage is detected replace the batteries with new ones.
Charging the batteries with an inverse polarity connection between the batteries and the charger could cause electrolyte leakage, heat generation, or a fire.
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.
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.
Do not remove or scratch the outer tube of the battery or it may cause an electrolyte leakage or electrical leakage.
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.
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.
Children should be taught how to handle and use the batteries correctly.
Keep the batteries out of the reach of small children at all times.
