The period of warranty is 12 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.
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 half a year
to prevent over-discharge.
