Precautions and Safety Instructions of Cylindrical Li-ion Battery

Please pay attention to followings in case of batteries will have leakage, heat etc.
Do not immerse the battery in water or seawater, and keep the battery in a cool dry surrounding if it stands by.
Do not use or leave the battery at high temperature as fire or heater. Otherwise, it can overheat or fire or its performance will be degenerate and its service life will be decreased.
Do not reverse the position and negative terminals.
Do not connect the battery electrodes to an electrical outlet.
Do not short circuit. Otherwise it will cause serious damage of the battery.
Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc.
Do not strike, trample, throw, fall and shock the battery.
Do not directly solder the battery and pierce the battery with a nail or other sharp objects.
Do not use the battery in a location where static electricity and magnetic field is great, otherwise, the safety devices may be damaged, causing hidden trouble of safety.
Use the battery charger specifically when recharging.
If the battery leaks and the electrolyte gets into the eyes, do not rub the eyes, instead, rinse the eyes with clean water, and immediately seek medical attention. Otherwise, it may injure eyes.
If the battery gives off strange odor, generates heat, becomes discolored or deformed, or in any way appears abnormal during use, recharging or storage, immediately stop charging, using, and remove it from the device.
In case the battery terminals are dirty, clean the terminals with a dry cloth before use. Otherwise poor performance may occur due to the poor connection with the instrument.
Tape the discarded battery terminals to insulate them.
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.
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.
Notice for Assembling Battery Pack: Shocks, high temperature, or contacts of sharp edge components should not be allowed in battery pack assembling process.

Storage of Cylindrical Li-ion Battery

Batteries should be stored at room temperature (Temperature: 25±2℃;Humidity:(65±20% RH).
Batteries are charged to about 30% to 50% of capacity.
Batteries’storage voltage should be 3.3~3.4V .
Batteries be charged about once per 3 months to prevent over discharge.

FAQ

1. Q: What is minimal rated capacity?

A: minimal rated capacity is the capacity on 0.2 C discharge till the voltage tapered to 2.0V shall be measured after rested for 30min then finish standard charge.

2. Q: What is internal impedance?

A: Internal impedance is measured at AC 1KHz after 50% charge.

3. Q: What is standard charge?

A: Charging shall consist of charging at a 0.2 C constant current rate until the cell reaches 4.20V. The cell shall then be charged at constant voltage 0f 4.20 volts while tapering the charge current Charging shall be terminat ed when the charging current has tapered to 0.02 C. Charge time:Approx 6.0h,The cell shall demonstrate no permanent degradation when charged between 0℃ and 45℃

4. Q: What is standard discharge?

A: Batteries shall be discharged at a constant current of 0.2 C to 3.0 volts @20℃±5℃. If no otherwise specified, the rest time between Charge and Discharge amount to 30min.

5. Q: What is overcharge?

A: After normal charge, test the batteries’ initial state and capacity. Charge to 10.0V at 3C, then charge at CV mode to 0.01C. Observe battery’s variation of appearance.

6. Q:What is over discharge?

A: After normal charge, test the batteries’ initial state. When the batteries are normal, Discharge to 0V at 0.5C.
