4. Battery Safety Precautions
1) Be sure to carefully read the user manual before using this product.
2) Ignore the following instructions may cause battery overheating, burning, explosion, damages the
performance and reduce the product life.
① Do not allow water, sea water from entering or leaking into the battery inside. If the battery internal
safety device burn, when charging it, it may produce abnormal current, voltage, and chemical reaction to
cause the battery overheating, burning and explosion.
② Do not use or place the battery nearby the stove or other high temperature places. Excessive heat may
damage the resin shell or the insulation materials, thereby cause short-circuit inside the battery and result
the battery overheating, burning and explosion.
③ When charging, use a specified charger. Other conditions (high temperature, high pressure/high
current, using the modified battery charger, etc.) excluded here may result in over-charging the battery
and abnormal current or voltage, cause abnormal chemical reaction, and may cause the battery
overheating, burning or explosion.
④ Do not make the battery contact with the power outlet or car cigarette lighter socket. This may cause
high pressure and excessive current, and lead the battery overheating, burning or explosion.
⑤ Do not heat the battery or put the battery into fire. This may melt insulation material and damage
safety devices or safety equipment, then ignite electrolytic solution, and cause the battery overheating,
burning or explosion.
⑥ Do not use the battery with contrary (+) and (-) location. In the charging process, this will cause the
reverse charging and may cause abnormal chemical reaction. During use, may appear unpredictable
current exception, and cause the battery overheating, burning or explosion.
⑦ Battery clearly marks with positive and negative. When connect the battery with the charger or printer,
be sure to verify the correct battery orientation. Reverse insertion will cause the reverse charging and
may cause abnormal chemical reaction, and then may cause the battery overheating, burning or explosion.
⑧ Do not make the battery (+) and (-) connect with any metal. Also, do not carry along or store batteries
with metal objects, such as necklaces, hair clips and so on. Battery internal short circuit may cause
excessive current, and lead to the battery overheating, burning or explosion and the adjacent metal objects
(necklaces, hairpins, etc.) may be overheated.
⑨ Do not throw or heavily attack the battery. If internal safety device of the batteries burned, the battery
charging may cause abnormal current and voltage, and abnormal chemical reaction, and lead the battery
overheating, burning or explosion
