5. CAUTIONS IN USE
To ensure proper use of the battery please read the manual carefully before using it. Handling
 Do not expose to, dispose of the battery in fire.
 Do not put the battery in a charger or equipment with wrong terminals connected.
 Avoid shorting the battery
 Avoid excessive physical shock or vibration.
 Do not disassemble or deform the battery.
 Do not immerse in water.
 Do not use the battery mixed with other different make, type, or model batteries.
 Keep out of the reach of children.
charge and discharge
 Battery must be charged in appropriate charger only.
 Never use a modified or damaged charger.
 Do not leave battery in charger over 24 hours
 Store the battery in a cool, dry and well-ventilated area.
 Regulations vary for different countries. Dispose of in accordance with local regulations.
6. Battery operation instruction
Charging
Charging current：Cannot surpass the biggest charging current which in this specification book stipulated。
Charging voltage：Does not have to surpass the highest amount which in this specification book stipulated to decide the
voltage。
Charge temperature：The battery must carry on the charge in the ambient temperature scope which this specification
book stipulated。
Uses the constant electric current and the constant voltage way charge, the prohibition reverse charges. If the battery
positive electrode and the cathode meet instead, can damage the battery。
Discharging current
The discharging current does not have to surpass this specification book stipulation the biggest discharging current,
the oversized electric current electric discharge can cause the battery capacity play to reduce and to cause the battery
heat。
Discharge temperature
The battery discharge must carry on in the ambient temperature scope which this specification book stipulated
Over-discharges
After the short time excessively discharges charges immediately cannot affect the use, but the long time excessively
discharges can cause the battery the performance, battery function losing. The battery long-term has not used, has the
possibility to be able to be at because of its automatic flashover characteristic certain excessively discharges the
condition, for prevented excessively discharges the occurrence, the battery should maintain the certain electric
quantity。
Storing the Batteries
The battery should store in the product specification book stipulation temperature range. If has surpasses above for
six months the long time storage, suggested you should carry on additional charge to the battery。

7. Period of Warranty
The period of warranty is one year from the date of shipment. Guarantees to give a replacement in case of cells
with defects proven due to manufacturing process instead of the customer abuse and misuse.
8. Other the Chemical Reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a
long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient
temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or
the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge
for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.
