If your brake lights are staying on, it will drain your battery. You need to disconnect your battery while the car is off or until you resolve this issue.

The most likely cause for the brake lights staying on is the brake light switch sticking closed. You can disconnect the plug from the brake light switch at the brake light pedal to see if the lights turn off. If they do, you will need a replacement brake light switch. Otherwise, you will need further electrical diagnosis.
