With all the electronics on today's cars looking for a spark when connection the battery will not tell you much. With multiple computers, each one may do a self check when first connected to power and then power down to almost no draw until the key switch is turned on.
I once worked on a 2004 GMC that would have a dead battery every Monday morning after not being used over the weekend.

It was supposed to draw about .5 amps when the key switch was first turned on and then drop to a few milliamps after about 30 seconds. To find the problem I connected a ammeter between the battery connection and the fuse panel and then started pulling fuses one at a time to see which one had the major draw. There were several that had quite a draw when first installed but then dropped off when the self check was done. The fuse that powered the instrument cluster and several other things would not power down. It was then a matter of disconnecting the other components powered by that fuse one at a time until the problem was found.
