Chamjin I&C CJ50SP, User Manual

■ Battery Safety Precautions Make sure to review the user manual carefully prior to product 
use. 
Neglecting to heed the following instructions can result in battery overheating, combustion, 
explosion, damage and/or decline in performance and product life. 
 

 
Danger 

1. Do not allow water, seawater, etc. enter or leak into the battery interior. If the safety 
mechanism within the battery becomes burned out, any charging of the battery can result 
in abnormal electrical current flow and/or voltage that causes an abnormal chemical 
reaction, which may then cause the battery to overheat, ignite, and/or explode. 
2. Do not use or leave the battery in a location exposed to high temperatures, such as 
next to a stove, etc. Excessive heat exposure can cause damage to the resin case and/or 
insulating materials, thus causing short circuits within the battery that may result in battery 
overheating, combustion, and/or explosion. 
3. When charging the battery, use the exclusive charger or follow the charging 
requirements outlined by CHAMJIN I & C. Charging under conditions not included in such 
requirements (higher temperature, higher voltage/larger electrical current, use of a 
modified charger, etc.) can result in excessive battery charging and abnormal electrical 
current flow and/or voltage that causes an abnormal chemical reaction, which may then 
cause the battery to overheat, ignite, and/or explode. 
4. The battery has clearly delineated plus and minus poles. When inserting the battery into 
the charger and/or product, make sure to confirm that the battery is properly aligned. 
Reverse insertion will cause reverse charging that can result in an abnormal chemical 
reaction, which may then cause the battery to overheat, ignite, and/or explode. 
5. Do not place the battery in contact with an electrical power outlet and/or an automobile 
cigarette lighter jack. Doing so can inflict high voltage that causes excessive electrical 
current flow, resulting in battery overheating, combustion, and/or explosion. 
6. Do not heat the battery or place it in a fire. Doing so can melt the insulating materials 
and/or damage the safety mechanism or safety equipment, allowing the electrolytic 
solution to ignite and resulting in battery overheating, combustion, and/or explosion. 
7. Do not use the battery in reverse (+) and (-) alignment. Doing so during charging will 
cause reverse charging that can result in an abnormal chemical reaction. During use, 
unpredictable electrical current abnormalities can arise, causing battery overheating, 
combustion, and/or explosion. 
8. Do not allow the battery’s (+) and (-) poles to come into contact with any metals. In 
addition, do not carry or store the battery together with metal items, such as necklaces, 
hairpins, etc. Resulting short circuits within the battery can cause excessive electrical 
current flow, resulting in battery overheating, combustion, and/or explosion as well as 
potential overheating of the adjacent metal items (necklaces, hairpins, etc.). 
9. Do not throw the battery or subject it to heavy shock. If the safety mechanism within 
the battery becomes burned out, any charging of the battery can result in abnormal 
electrical current flow and/or voltage that causes an abnormal chemical reaction, which 
may then cause the battery to overheat, ignite, and/or explode.
