Because the battery's life depends solely on how frequently the SQUARE ENIX Security Token is used, we cannot give a specific length of time. If the battery dies within 3 months from the purchase, we will exchange the non functioning SQUARE ENIX Security Token with a new SQUARE ENIX Security Token free of charge.

Please do not exchange the SQUARE ENIX Security Token battery yourself since the data will be erased, and the SQUARE ENIX Security Token can no longer be used.
