WARNING: Failure to follow these safety precautions may lead to a serious accident. SAFETY CHARGING BATTERY The battery can explode if handled incorrectly during charging. Be sure to heed the following and check safety information supplied by the battery charger manufacturer. Remove the battery caps to disperse hydrogen gas and charge in a well-ventilated area. Set the voltage of the charge to match the voltage of the battery to be charged. If mismatched, the charger may overheat and catch fire. Connect the positive (+) charging clip of the charger to the positive (+) terminal of the battery, then connect the negative (-) charging clip to the negative (-) terminal of the battery.
Be sure to tighten both terminals securely. If the battery charge is less than 1/10 of the rated charge, and high speed charging is carried out, set to a value below the rated capacity of the battery. If there is an excessive flow of charging current, the battery electrolyte may overflow and evaporate, catch fire, or explode. WA450-3MC 1-21
