Abstract: A method for charging a non-aqueous electrolyte secondary battery, the battery comprising a positive electrode that comprises a lithium-containing composite oxide, a negative electrode, and a non-aqueous electrolyte. The method comprises the step of detecting an open-circuit-voltage of the battery to determine which of voltage regions A, B and C the detected value is included in. The region A is not smaller than a prescribed value X. The region B is smaller than the prescribed value X and larger than a prescribed value Y (Y
