Special Notes:

There are three kind of Connectors, please choose the correct version you need.

As a manufacturer of batteries, we can customize the connector you need,if you need any other types,please contact us.

Due to the fact that batteries are a special item and the transportation method has limitations, the logistics are 5 to 10 days slower than ordinary products.

Please be patient.

Thank you for your understanding.

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

3 Avoid shorting the battery.

4 Avoid excessive physical shock or vibration.

5 Do not disassemble or deform the battery.

6 Do not immerse in water.

7 Do not use the battery mixed with other different type or model batteries.

8 Keep out of the reach of children.

Storage

1, The Li-ion battery pack should be stored in a cool, dry and well-ventilated area, and should be far from the fire and the high temperature.

2, The battery should store in the product specification book stipulation temperature range, the best storage temp. is 25±5℃. The best humidity is 60±15%.

3, The battery should be stored within room temperature, and charged to 40%~60% electric quantity（3.85V）. In order to avoid over-discharge, we suggest charge and discharge the batteries every three months.,Then charge to40%~60%electric quantity(3.85V).

Transportation
