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.
