Query: Easy to Install but No Battery Fits

This was easy to assemble and install, but the mechanism on the back indicates it takes an AAA battery and is clearly too large for AAA. I thought maybe it was a misprint and tried an AA... nope! Too small for an AA. I'm not sure how something can be made and not fit standard battery sizes, but this one fails. Assembly was quick and easy, but totally useless since there's no battery that fits to make the clock actually run.
