Warning
1. If the battery is not charged after the charging time, stop charging and contact the supplier.
2. Store and use the battery where it will not come into contact with liquid (water, salt water,
etc.). There may be a risk of overheating, rupturing or igniting.
3. Avoid exposing the battery to high temperatures over 50℃ and do not store or use it in a
place with high temperature and humidity. There may be a risk of overheating, rupturing or
igniting. In addition, it may reduce the performance and life of the battery. There is a risk of
explosion, especially when the battery is placed by a fire or stored near a heating device
(e.g., heater, etc).
4. Do not put the battery in a microwave oven or high-pressure cooker (pressure cooker, etc.).
There may be a risk of overheating, rupturing or igniting.
5. Do not use or leave the battery exposed to direct sunlight or high temperatures such as in
a car. It may reduce battery performance and life, or there may be a risk of overheating,
rupturing or igniting.
6. The usage temperature range of the battery is as follows. If used outside of this range,
battery performance and life may be reduced, or there may be a risk of overheating,
rupturing or igniting.
- Charging: 0 to 40°C (32 to 104°F)
- Using: -15 to 50°C (5 to 122°F)
- Long-term storage (over 30 days): -15 to 40°C (5 to 104°F)
7. Be sure to only use an adaptor or charger approved by us to charge the battery. Use of
any other adaptor or charger may reduce battery performance and life, or cause a risk of
overheating, rupturing or igniting.
8. Do not use the (+) and (-) terminals of the battery reversely. Failure to use the equipment
may result in an abnormal chemical reaction inside the battery, which may cause
overheating, rupturing or igniting.
9. Do not touch the (+) and (-) terminals of the battery with metal. Also, do not carry or store it
with metallic goods (necklaces, hair pins, coins, etc.). There may be a risk of overheating,
rupturing or igniting.
10. Do not use the battery in a place where static electricity can be generated. It may damage
the device, resulting in reduction of battery performance and life, or there may be a risk of
overheating, rupturing or igniting.
11. Avoid causing any strong impact to the battery or throwing it. The protective device inside
the battery may be damaged, which may reduce the battery performance and life, or there
