Packaging & Delivery
According of the transportation rule , the battery pack have to pack individual avoid short cicle
the total weight for each carton less than 6 kgs.
Storing the Batteries
The batteries should be stored at room temperature, charged to about 30% to 50% of capacity.
We recommend that batteries be charged about once per three months to prevent over-discharge.
Period of Warranty
The period of warranty is 18 months from the date of shipment. TAC guarantees to give a replacement in case of battery with defects proven due to manufacturing process instead of the customer abuse and misuse.
