DANGER
Handling the battery
- Use the specified battery charger and observe the specified charging conditions when charging. If you do not, the battery may overheat, burst, or ignite.
- Do not leave the battery near heat sources such as heaters. If you do not, the battery may burst or ignite.
- Do not heat the battery or throw it into a fire. If you do not, the battery may burst or ignite.
- Do not deform, modify, or disassemble the battery, and do not directly apply solder to the battery terminals. If you do not, liquid leakage, overheating, bursting, or ignition may occur.
- Do not short-circuit the terminals with metallic objects. If you do not, a short-circuit or overheating may occur, resulting in burns or other injury.
- Do not carry or store the battery together with metallic objects such as necklaces or hairpins. If you do not, a short-circuit or overheating may occur, resulting in burns or other injury.
- Do not immerse the battery in fresh or salt water, and do not allow the battery terminals to get wet. If you do not, overheating, bursting, or ignition may occur.
- Do not subject the battery to strong impact or throw it. If you do not, overheating, bursting, or ignition may occur.
- In the event of a battery fire, take the following measures:
If possible, carefully keep other batteries away from the fire.
Evacuate all persons from the immediate area of the fire.
Extinguish the fire with large amounts 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 follow this may result in electric shock or injury.
- Use the specified battery and charger combination for charging, and observe the specified charging conditions. Only charge rechargeable batteries. If you do not, the battery may overheat, burst, or ignite.
- If the battery is not fully charged after 2 hours beyond the specified charging time, immediately disconnect the battery from the power outlet and contact the place of purchase. If you do not, the battery may overheat, burst, or ignite.
Refer to "Specified charging time."
- Do not allow the battery charger to get wet. If it gets wet or water gets inside, it may ignite, overheat, or cause electric shock.
- Do not use it while wet, and do not touch or hold it with wet hands. Electric shock may result.
- Do not cover the battery charger with cloths or similar materials during use. If you do not, heat may build up, deforming the case, causing a fire, ignition, or overheating.
- Only use the battery charger at the specified power supply voltage. If the power supply voltage is other than the specified value, fire, explosion, smoking, overheating, electric shock, or burns may result.
WARNING:
Handling the battery
- Use the product under the supervision of a person responsible for safety and only as instructed. Do not allow anyone (including children) with reduced physical, sensory or mental ability, or persons with no 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. If you do not, the battery liquid may 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, keep 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, fire, battery damage, or operating problems may occur.
1. During discharge: -10 – 50 °C
2. During charging: 0 – 40 °C
Temperatures above 60 °C may cause leakage and bursting of the battery.
- Do not use the battery if there are noticeable scratches or other external damage. Failure to follow this may result in bursting, overheating, or operating problems.
- Do not use products with broken seals. Immediately hand them in for appropriate recycling. (Screw heads on the cover are sealed with adhesive or a cover.)
- Do not use the battery if it exhibits liquid leakage, discoloration, deformation, or other abnormalities. Failure to follow this may result in bursting, overheating, or operating problems.
- 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. cleaning agents).
Handling the battery charger
- Hold the mains plug when connecting or disconnecting the cable. Failure to do so may result in fire or electric shock.
- If any of the following symptoms occur, stop using the device and consult the place of purchase. Fire or electric shock may result.
If pungent smoke comes out of the mains plug or the plug is hot.
There is a poor connection inside the mains plug.
- During a thunderstorm, do not touch the metal parts of the mains plug or AC adapter. Electric shock may result from a lightning strike.
- Do not overload the electrical outlet with appliances that exceed the outlet's rated capacity, and only use a 100 – 240 V AC power supply outlet. If the electrical outlet is overloaded by connecting a large number of appliances using adapters, overheating may occur, resulting in fire.
- Do not damage the power cord or mains plug. (Do not damage, modify, forcibly bend, twist, or pull them; do not place them near hot objects, place heavy objects on them, or tightly bundle them together.) If used in a damaged state, fire, electric shock, or short-circuiting may result.
- Do not use the battery charger in conjunction with commercially available electrical transformers designed for overseas use (travel converters). This may cause damage to the battery charger.
- Always insert the mains plug all the way. Failure to do so may result in fire.
- Do not insert or remove the plug when it is wet. Electric shock may result. If water is leaking from the plug, thoroughly dry it before inserting the plug.
- Do not charge the battery in damp locations or areas with high humidity. (EC-E8004) Do not charge the battery in damp locations, areas with high humidity, or outdoors. (Battery charger other than EC-E8004) Fire, ignition, overheating, or electric shock may result.
- Do not move the bicycle while charging the battery when it is installed on the bicycle. The mains plug of the battery charger may become loose and may not be fully inserted into the electrical outlet, posing a risk of fire.
