�.�  Storage

�.� Transportation

�.�  Charging the battery before use

The battery is fully charged to approximately ��% when shipped from the factory. It is 
recommended to fully discharge and charge the new battery before use.

�.�  Maintenance

No direct maintenance is required. To maintain the battery, keep the connection electrode and 
the surface clean, tighten the clamp and lightly grease. Use at least once every three months to 
maintain the battery and calibrate the state of charge.

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.
The best Voltage in storage is  ��.�V~��.�V.
The battery should be stored in the temperature range of the product specification. The 
best storage temperature is �~��°C. The best humidity is �� ± ��%. 
If there is a long storage period of more than � months, it must charge and discharge the
battery extra.

Do not mix the battery products with other cargo.  
Do not immerse the battery products in water or get it wet.
The maximum temperature during transportation is below ��°C.
