9. Do no t pierce the ba ttery w ith a s harp obj ect or hi t i t w ith a h eavy obj ect. Avoid
accidental s hort c ircuiting of any bat tery. A llowing bat tery t erminals t o c ontact
conductive m aterial w ill c reate a s hort c ircuit, which c ould c ause b urns and ot her
injuries or could start a fire.
The battery may rupture or become warped, causing short
circuits, which may result in battery overheating, combustion, and/or explosion.
10. Do not solder the battery directly. The heat may melt the insulating materials and/or
damage the safety mechanism or safety equipment, resulting in battery overheating,
combustion, and/or explosion.
11. Do not disassemble and/or modify the battery. The battery contains safety equipment
and a safety mechanism to prevent danger. Any damage to these components can
cause battery overheating, combustion, and/or explosion.
12. Do not charge near a s ource of heat and/or under direct sunlight. Exposure to high
temperatures may ca use the s afety mechanism t o ac tivate, t hus m aking c harging
impossible. In addition, any damage to the safety mechanism may result in abnormal
electrical current flow and/or voltage that causes an abnormal chemical reaction within
the battery and/or battery overheating, combustion, and/or explosion.
13. Do not expose the battery to high temperatures over 60C (140F), and do not use or
store it in a hot or humid place.
14. Do no t us e t he b attery i f i t i s dam aged or t he ex terior i s def ormed due to ex ternal
shock or if it is swollen.
Warning
1. Do not place the battery within the reach of small children to prevent any swallowing
accidents. If a small child has swallowed the battery, consult a physician immediately.
2. Do not place the battery in a m icrowave oven and/or high voltage appliance. This may
cause r apid overheating and/ or des truction o f t he s ealing, r esulting i n bat tery
overheating, combustion, and/or explosion.
3. Do not combine and use any battery of different capacity and/or type with the primary
battery. This m ay cause excessive el ectrical di scharge d uring us e or ex cessive
charging during charging, resulting in an abnormal chemical reaction within the battery,
which can cause battery overheating, combustion, and/or explosion.
4. If during battery usage, storage, or charging, a strange odor or conditions differing from
normal oper ations (such as ov erheating, c olor c hanges, or warping) are det ected,
remove t he b attery from the pr oduct or c harger and di scontinue u se. Continued u se
may cause battery overheating, combustion, and/or explosion.
5. If the battery is not charged after the normal fixed charging time, discontinue charging.
Continued charging may result in battery overheating, combustion, and/or explosion.
6. If the battery contains condensation or emits a strange odor, immediately remove it from
any heat s ource. The c ondensation may be c aused by a l eak of electrolytic s olution
that can ignite, resulting in battery combustion and/or explosion.
7. If t he b attery i s l eaking electrolytic s olution an d the s olution e nters the ey es,
immediately rinse the eyes with clean water, and then consult a physician. Neglecting
to do so may cause permanent eye injuries.
