No. It has none if and when the power goes out. Auto Reset is why i purchased this item. Don't count on the battery for backup. There is none. I've gone through 2 units. It does not work.

On top of your clock, the press the small button on the far left, through a series of different modes, until the "minutes" flash. Then press the oblong button with "-" on it until the desired time is shown. Press the first button through gthe modes, until everything stops flashing. Good Luck.
