A: yes it has a compartment for batteries for back-up.
A: Yes, there is a battery backup requiring 2 AAA batteries
A: Yes there is an option for batteries
A: Yes it takes two AAA batteries

A: Numbers stay lit all night (though there are three setting for bright, medium, and dim)
A: They stay lit. It's very bright and you must manually choose between three brightness settings.
A: Yes they stay lit. You can change the brightness of the numbers
A: If the brightness is a problem at night for you like it was for us (even with the three brightness levels), don't be afraid to take a razor blade and pry up the front corners (using credit cards to keep it apart) and pull the front piece off. It is simply double sided tape holding it on. Then cut one or two strips of paper (~50mm x ~155mm) and place them in front of the digits. Enjoy!
A: Although there is a battery slot, I found the clock does NOT work with batteries in there and unplugged.
A: Yes there is a spot to insert two AAA batteries

A: Return it to the store
A: I would contact Capello (the maker of the clock) or Target to see if there may be a warranty. (This section is typically for customer question and answer - you'd have to contact Target directly for them to repond)
A: To set an alarm, you hold down the alarm clock button, wait for the number to flast, use the + and - buttons to set your correct time, and then hit the alarm clock button again when you're done. There should be a small like next to an alarm clock image in the bottom left corner signifying the alarm has been turned on.
A: Just hold down the alarm button on the top and as the digits flash, use the + or - buttons to change your desired time.
A: There is a dot that lights up in the bottom right corner for PM. When the light is not on, that signifies AM.
A: It is defaulted set to am.. Press the button til you see PM

A: There is a snooze bar on the top of the clock...
