7 Battery operation instruction
7.1 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。

7.2 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。
7.3 Electric discharge temperature
The battery discharge must carry on in the ambient temperature scope which this specification book
stipulated.
7.4 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。
7.5 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。
8. Period of Warranty
The period of warranty is a year from the date of shipment. We guarantees to give a replacement in case
of cells with defects proven due to manufacturing process instead of the customers abuse and misuse.
9. 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.
10. Note: Any other items which are not covered in this specification shall be agreed by both parties.
