- If the battery catches fire, take the following measures:
If possible, carefully keep other batteries away from the fire.
Evacuate everyone from the immediate area of the fire.
Extinguish the fire with a large amount of cold water (at least 10 times the weight of the battery blocks).
Handling the Battery Charger
- Do not disassemble or modify the battery charger. Failure to do so could result in electric shock or injury.
- Be sure to use the specified battery and charger combination and observe the specified charging conditions when charging. Only charge rechargeable batteries. Otherwise, the battery may overheat, burst, or ignite.
- If the battery is not fully charged after 2 hours of charging after the specified charging time, immediately unplug the battery from the power outlet and contact the place of purchase. Otherwise, the battery may overheat, burst, or ignite.
Refer to "Specified Charging Time."
- Do not allow the battery charger to get wet. If the battery charger gets wet or water gets inside it, it may ignite, overheat, or cause electric shock.
- Do not use it while wet, and do not touch or hold it with wet hands. Doing so may result in electric shock.
- Do not cover the battery charger with cloths or similar materials during use. Otherwise, heat may build up, deforming the case, causing fire, ignition, or overheating.
- Only use the battery charger at the specified power supply voltage. If the power supply voltage is different from the specified value, it may cause fire, explosion, smoking, overheating, electric shock, or burns.
WARNING:
Handling the Battery
- Use the product under the supervision of a person responsible for safety and only according to instructions. Do not allow anyone (including children) with reduced physical, sensory or mental ability, or persons without experience or knowledge to use the product. Do not allow children to play near the product.
- Keep out of reach of children.
- If liquid leaking from the battery gets into your eyes, immediately rinse the affected area thoroughly with clean water (tap water) without rubbing your eyes, and seek immediate medical attention. Failure to do so may cause the battery liquid to damage your eyes.
- If leaking liquid gets on your skin or clothing, immediately wash it off with clean water (wash for at least 15 minutes). The leaking liquid may damage your skin.
- Medical attention is required for symptoms caused by accidental ingestion of battery liquid, contact with skin or eyes, or inhalation of battery combustion products.
- If you accidentally inhale fumes or vapors, immediately move to a place with fresh air, stay warm and quiet, and seek professional medical attention if necessary.
- Do not use the battery outside the specified operating temperature range. If the battery is used or stored at temperatures outside these ranges, it may cause a fire, damage the battery, or cause problems during operation.
1. During discharge: -10 – 50 °C
2. During charging: 0 – 40 °C
Temperatures above 60 °C may cause the battery to leak and burst.
- Do not use the battery if it has obvious scratches or other external damage. Failure to do so may cause bursting, overheating, or problems during operation.
- Do not use products with broken seals. Return them immediately for appropriate recycling. (The screw heads on the cover are sealed with adhesive or a cover.)
- Do not use the battery if it shows signs of leakage, discoloration, deformation, or other abnormal signs. Failure to do so may cause bursting, overheating, or problems during operation.
- Batteries must not come into contact with solvents (i.e. thinners, alcohol, oil or anti-corrosion agents) or chemicals that affect the surface (i.e. detergents).
Handling the Battery Charger
- When connecting or disconnecting the cable, hold it by the mains plug. Failure to do so may result in fire or electric shock.
- If the following symptoms occur, stop using the device and contact the place of purchase. Fire or electric shock may occur.
If pungent smoke comes out of the mains plug or the plug heats up.
There is a poor connection inside the mains plug.
- During a thunderstorm with lightning, do not touch the metal parts of the mains plug or AC adapter. Electric shock may occur if struck by lightning.
- Do not overload the electrical outlet with appliances that exceed the outlet's rated capacity, and only use a 100-240 V AC power outlet. Overloading an electrical outlet by connecting a large number of appliances using adapters may cause overheating resulting in fire.
- Do not damage the mains cable or mains plug. (Do not damage, modify, forcibly bend, twist or stretch them; do not place them near hot objects, place heavy objects on them or tie them tightly together.) If used in a damaged condition, fire, electric shock or short circuit may occur.
- Do not use the battery charger in conjunction with commercially available electrical transformers designed for use abroad (travel converters). This may damage the battery charger.
- Always insert the mains plug all the way in. Failure to do so may result in fire.
- Do not insert or unplug the plug when it is wet. Otherwise, electric shock may occur. If water is leaking from the plug, dry it thoroughly before inserting it.
- Do not charge the battery in damp places or areas with high humidity. (EC-E8004) Do not charge the battery in damp places, areas with high humidity or outdoors. (Battery charger other than EC-E8004) Fire, ignition, overheating or electric shock may occur.
- Do not move the bicycle while charging the battery installed on the bicycle. The mains plug of the battery charger may be loose and may not be fully inserted into the electrical outlet, which poses a risk of fire.
