Application
Period of Warranty
The period of warranty is six months from the date of shipment. TAC guarantees to give a replacement in case of cells with defects proven due to manufacturing process instead of the customers abuse and misuse.
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 year to prevent over discharge.
