Transportation

The battery's shipping state of charge is 30%~50% SOC. Batteries should be packed into boxes for shipping. During transportation, it should be prevented from severe vibration, impact or extrusion, protected from sun and rain, and must not be turned upside down.

During the loading and unloading process, products should be handled with care, and strict precautions should be taken to prevent throwing, rolling, and heavy pressure.

Storage

Batteries stored for longer than 6 months must be placed in a dry and ventilated place. The storage state of charge is 20%~50% SOC, and the battery is charged and discharged every 6 months.

Precautions

a) Do not put the battery into fire or heat it.

b) Do not short-circuit or overcharge the battery.

c) Do not subject the battery to excessive mechanical impact.

d) Do not immerse the battery in sea water or water, or allow it to absorb moisture.

e) Do not reverse the positive and negative poles of the battery.

f) Do not disassemble or repair the battery.

g) Do not cause the battery to be significantly damaged or deformed.

h) Do not touch the leaking battery directly.

i) Keep batteries away from children.

j) Do not needle, hammer or step on the battery.

k) Do not hit or throw the battery.
