¤ WARNING: For reasons of safety, always follow these safety precautions. 7. PRECAUTIONS DURING OPERATION 1-24 CHARGING BATTERY When charging the battery, if the battery is not handled correctly, there is danger that the battery may explode. Always follow the instructions for use of the battery and the instruction manual accompanying the charger, and do as follows. ‡ Take the charger to a well-ventilated place and remove the battery caps. This is to disperse the hydrogen gas and prevent explosion. ‡ Set the voltage of the charger to match the voltage of the battery to be charged. If the voltage is not selected correctly, the charger may overheat and cause an explosion.
‡ Connect the positive + charger clip of the charger to the positive + terminal of the battery, then connect the negative - charger clip of the charger to the negative - terminal of the battery. Be sure to fix the clips securely. ‡ Set the charging current to 1/10 of the value of the rated battery capacity; when carrying out rapid charging, set it to less than the rated battery capacity. If the charger current is too high, the electrolyte will leak or dry up, and this may cause the battery to catch fire and explode. A0055110
