Normal Packing For Battery Pack
50pcs in one inner box , 10 box in one carton
The package with un38.3 certification require
The batteries should be stored under room temperature, charged
to about 30% to 50% of capacity.
We recommend that batteries be charged about once per half a year to prevent over discharge
The period of warranty is one year from the date of shipment. Great Power guarantees to give a replacement in case of cells with defects proven due to manufacturing process instead of the customer abuse and misuse.
