Welcome to the forum, check for any lites that may be left on, interior-- under the hood-- in the trunk-- glove box. Best time to check is in the dark. You can probably take a battery cable loose, use testlite between cable and terminal, if testlite comes on, there is a drain. You pull fuses, one at a time, till the testlite goes out, when you pull the fuse that effects the lite the most, the short is on that circuit.

The best way is to check for excessive amp draw, pull fuse till the amp draw drops to normal.
