Take the battery back and get a new one. They have a warranty. Some batteries are bad...

I would also look for parasitic draw. Do the batt terminals spark at all when removed or installed? That would be a dead giveaway on a terc(this means nothing on newer more electrical dependent cars).

If the battery checks out you will need an amp meter to thoroughly test for it. 25-35 milliamps or less is what you need. Newer cadillacs allow as much as 50 to keep all their computers memory going but all we have is a dash clock and stereo memory if it's not stock. If there is a parasite and it's not drawing too much a 12 volt bulb can suffice as a tester. Can't exactly remember the old school spec, if you can call it that, but with a bulb hooked in series at either terminal it should be very dim to no light. If it's too much draw you will smoke the bulb like a fuse.

If it lights, pull fuses one at a time until the light goes out. Alternator could be leaking as well and should be disconnected if fuse pulling doesn't find it.

are you sure the alternator is working? If it does not charge it might appear the battery is bad. But even new batteries can go bad fairly fast, I had to replace several new batteries within the first month of ownership in the last few years.

Turn on the lights at night against a wall, then start the engine and rev it. If the lights get brighter than the charging circuit is working. Or use a volt-olm meter. This can be used to see if you are leaking a charge when the engine is off.

good luck.

Rip the stereo deck out and wait a few days. Best way to test right there, also very easy if you have a ....crap i'm blanking on the word, oh, the right harness. If you have the right harness it should just unclip and it's super easy.

Just rewire the deck, a wire or two probably got messed up. Or get a new stereo deck.

Tape it off, or maybe use it for rigging up a light for the junk pocket beneath the deck
