Do I need to worry about voltage when using button batteries to power LEDs?

I am stringing up the LEDs powered by button batteries in my room, they last only for a few hours, but I was wondering if I need to make sure that the battery and the LEDs need to have compatible voltage if I am using them for short period. Can someone please help me regarding my query? Do I need to worry about voltage when using button batteries to power LEDs? I would really appreciate your feedback at the earliest. Thanks.
