6. Transportation & Storage

* Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.

* Battery should be stayed in the warehouse 15℃~35℃ where is dry, clean, shade, and well-ventilated.

* The battery should be stored in 50% SOC during transportation.

* The battery need to be charged every 6 months if out of use

* Keep the battery against dropping, turning over and serious stacking during loading

7. Warning & Tips

Please read and follow the specification and user manual before use the battery. Improper use may cause heat, fire, rupture, and damage or capacity deterioration of the battery. SHENZHEN TOPBAND BATTERY CO., LTD. shall not be responsible for any accidents caused by the usage without following our specification.

² The battery must be far away from heat source, high voltage, and avoid to be exposed in sunshine for long time.

² Never throw the battery into water.

² Do not put the battery in a charger or equipment with wrong terminals connected.

² Never connect the positive and negative of battery with metal.

² Avoid excessive physical shock or vibration. Don't hit, fall, stamp on the battery.

² Without the permission of the manufacturer and guidance, forbidden to remove or to assemble the battery

² Do not use the battery mixed with other different manufacturer, type, or model batteries.

² Keep the battery against high temperature. Otherwise, it will cause battery heat, get into fire or lose some function and reduce the life.

² When battery run out of power, please charge your battery timely (≤15day).

² Please use the matched or suggested charger for this battery.

² If battery emits peculiar smell, heating, distortion or appears any abnormity during working or storage, please stop using and take it out from device.

² If the battery leaks and get into the eyes or skin, do not wipe, instead, rinse it with clean water and see doctor immediately.

² Please keep it far away from children or pets.

² Do not put disuse battery into a fire or water.

² It is strictly prohibited any series between the battery packs. Any requirements on serials connection, please contact TOPBAND for details.

8. Operation instruction

Charge and discharge

1. Charging current: Do not surpass the largest charging current that specification stipulated.

2 .Charging voltage: Do not surpass the highest limited voltage that specification stipulated.

3 .Charging temperature: Within temperature scope that specification stipulated.

4. Charge with constant current, then with the constant voltage, no reverse charge, which is dangerous

5. Special notes: Short time over discharge or over charge doesn't affect the use of the battery, but for a long period of time over discharge or over charge can cause the function of the battery fail, or the battery can't use permanently and appear serious safety hazards. Please follow the recommended floating model parameters when it needs long time floating. When the Battery not in use for a long time, it can also discharge because of its own self-discharge characteristics, to prevent the occurrence of over discharge, battery should maintain a certain capacity; maintain the voltage at 50% state of SOC.

9. Other 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 discharge time is much shorter than the normal after full charged, even battery is charged correctly, and this may indicate it is time to change the battery.
