Trunk or glove box light stick on?

Load Test may tell the story....BAD CELL likely!!

Brake light switch could be bad.
Allowing brake lights to remain on when pedal is released thus killing the battery.

That was happening to my Marauder, would last about a day without starting, turned out to be the radio, old casket was stuck & draining the battery.
