Small 12V batteries

I'm trying to make a simple LED circuit with switch included in the circuit. Can someone suggest to me a 12V battery that is big enough to keep a 48 LED bulb system on for at least 24 running hours, but small enough to be the size of two fingers sticky taped together.

Thanks guys,

Yes, it is.  And part of "your" problem is that the site maintainers decided to remove the link to the "Answers" section from the masthead.  Here's the URL to your question: https://www.instructables.com/answers/Can-anyone-suggest-a-small-and-powerful-12V-batte/
