Handling Instructions for Battery
Please read and follow the handling instructions for the battery before use. Improper use of the battery may cause heat, fire, explosion, damage, or capacity deterioration of the battery.
- Do not place or leave the battery and equipment within the reach of infants so that they are not able to swallow or mistreat the battery by mistake. In case of ingestion, consult a doctor immediately.
- Do not let leaked electrolyte come into contact with eyes or skin. In such a case, immediately wash the area of contact with clean water and seek help from a doctor. If not treated soon, prolonged contact may cause serious injury.
- Do not put the battery into a fire. Do not use it or leave it in a place near fire, heaters, or high-temperature sources. In such a case, the insulator in the battery may be melted, the safety vent and structure may be damaged, or the electrolyte may catch fire, all of which may cause heat generation, explosion, or fire.
- Do not submerge the battery in water or wet the battery.
- Do not use or leave the battery near fire or in a car under the blazing sun. Such a high temperature may cause damage to the protective device in the battery, which may result in an abnormal reaction, and then heat generation, explosion, or fire.
- Do not connect the battery reversed in positive (+) and negative (-) terminals in the equipment.
- Do not let the battery terminals (+ and -) contact a wire or any metal (like a metal necklace or a hairpin) with which it is carried or stored together. In such a case, the battery will be shorted and cause an excessive current, which may result in heat generation, explosion, or fire.
- Do not connect the battery directly to an electric outlet or cigarette heater socket in a car. With a high voltage applied, the battery may overheat, explode, or cause fire.
- Do not throw or drop the battery. Strong impact may damage the protective device, which may cause an abnormal chemical reaction during charging and result in heat generation, explosion, or fire of the battery.
- Do not drive a nail into, hit with a hammer, or stamp on the battery. In such a case, the battery may be deformed and shorted, which may cause heat generation, explosion, or fire of the battery.
- Do not solder the battery directly. Heat applied during soldering may damage the insulator of the safety vent and mechanism, which may result in heat generation, explosion, or fire of the battery. The battery employs a safety mechanism and a protective device in order to avoid any danger. If these are damaged, heat, explosion, or fire may be caused.
CAUTION
- Do not put the battery in a microwave or a pressure cooker. Sudden heat may damage the seal of the battery and may cause heat generation, explosion, or fire of the battery.
- Do not use the battery with other makers’ batteries, different types, and/or models of batteries, such as dry batteries, nickel-metal hydride batteries, or nickel-cadmium batteries.
- Do not leave the battery in the equipment if it generates an odor and/or heat, changes color and/or shape, leaks electrolyte, or causes any other abnormality.
- Do not use the battery in a place where static electricity (more than the limit of the manufacturer’s guarantee) occurs. Otherwise, the protective device in the battery might be damaged and cause heat generation, explosion, or fire.
- Do not use the battery in conditions other than the operating conditions; otherwise, the battery might cause heat generation, damage, or deterioration of its performance.
Please read and follow the above safety information when operating the device. We cannot guarantee that no accidents or damage will occur due to improper use of the device. Please use this product with care and operate at your own risk.
