4. Battery Safety Precautions
Be sure to carefully read the user manual before using the product.
Ignore the following instructions may cause battery overheating, fire, explosion, damage
and / or performance, and reduced product life.
1) Do not allow water, sea water from entering or leaking into the battery inside. If the
batteries internal safety device burn, when charging it, it may produce any abnormal
current and / or voltage, and cause any abnormal chemical reaction, then may cause the
battery overheating, fire and / or explosion.
2) Do not use or place the battery nearby the stove or other high temperature places.
Excessive heat maybe damage the resin shell and / or the insulation materials, thereby
cause short-circuit inside the battery, then the battery may be caused overheating,
burning and / or 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 and / or voltage, cause abnormal
chemical reaction, and may cause the battery overheat, light and / or explosion.
4) Battery clearly marks with positive and negative. When connect the battery with the
charger and / 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 overheat, ignite, and / or explosion.
5) Do not make the battery contact with the power outlet and / or car cigarette lighter
socket. This may cause high pressure and excessive current, and lead to the battery
overheat, burning and / or explosion.
6) Do not heat the battery or put the battery into fire. This may melt insulation material and
/ or damage safety devices or safety equipment, then ignite electrolytic solution, and
cause the battery overheat, burning and / or explosion.
7) 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 overheat, ignite, and /
or explosion.
8) Do not make the battery (+) and (-) contact with any metal. Also, do not carry along or
store batteries with metal objects, such as necklaces, hair clips and so on. Battery internal
