Battery drains within hours to a day after it is jumped?

So I charged my battery today to 75%. I just removed the ac compressor relay. I'll post an update tomorrow to see if the battery still drains. But it does explain why every time I disconnect and reconnect the battery, my ac is running even though I never turned it on before disconnecting the battery or jumping the car.

I charged the battery to 100%. I havent put it back in yet, im going to re install when I go to work tonight and see what happens when I get off in the morning. I'll KYP.

Also, thanks in advance for all the advice and taking the time to respond to my question and replies.

So, I waited two days to see if my battery would die and lo and behold I am once again charging my battery. The A/C compressor relay was blown but the battery is still draining.

So, my next process of elimination is im going to replace the BCM. I cleaned the corrosion from the battery terminals. Replaced the fuses and still its draining.

Battery is one month old, starter 3 wks old, alternator 3 wks old, 175amp fuse 2 wks old, ac compressor fuse relay, 1 wk old.

No lights are left on. I double and triple checked just to be sure. I reconditioned the battery with my battery charger for about 8 hours after charging it up. I just may have to suck it up and take it to a shop.

This morning about 20 minutes ago, I heard my battery dying. I was sitting in my truck and all of a sudden the electronics started going crazy. I heard ticking coming from my door locks, it ticked like my. Hazards were on but the flashers never came up on the cluster. My ac unit lit up but never came on. And it was
just a constant and rapid clicking from everywhere as I heard I get lower and lower until the battery finally died.

Well, the alternator isnt warm, but I do remember now that the battery was very warm to the touch. It almost felt swollen to the point of exploding. I was almost scared to put it on the charger. But I put it under ventillation and did the reconditioning after charging it up. I feel like my BCM is bad too. Ill be replacing it soon too.

The battery is definitely bad. Also after driving this morning, I went to disconnect the battery and noticed the alternator was hot to the touch. So I deduced that the voltage regulator is either going out or has already gone out. So im ordering a new one from Covert Chevrolet. He said it should be next day delivery.

Oh. I'm still replacing the BCM, the voltage regulator and battery. Will the bad battery affect anything? I'll replace the battery in a few days. And also, I'm hoping to set up a dual battery configuration. Is that a good idea considering it's only factory accessories that's in the vehicle, besides the aftermarket radio?

Okay, it will be changed very soon. Thanks a lot.
