I replace the battery and then my new battery did the same thing and then I thought that it was my alternator, so I got a new alternator and the battery went dead again. I checked the corrosion didn't see any on the wires. I don't know what to do.
Ok,It sounds like you have a parasitic draw,
I looked up what you said that it could be and I well go and get a multimeter to test the battery and alternator thank you very much

Suggest you get a meter and measure the voltage on the battery in the car with the engine off and then running. Should be 12. 5 off and 14.1 running. Readings are approximate, but you should see around 2 volts difference between off and running. Less than 12 volts off, indicates a defective battery, especially if you reading 10 or 11 volts.
Ok checked it running it w .35 so bad alternater and had it tasted auto store said good
