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.
The period of warranty is 1 year from the date of shipment.TAC BATTERY guarantees to give a replacement in case of battery with defects proven due to manufacturing process instead of the customer abuse and misuse.
