2002 Ford escape battery drain problem

Most of the time the leads on the battery are a culprit. Try changing them out with new ones and see if that helps. We have a 2002 Mazda Tribute which is basically an escape at work and same issue. Battery drains quick and no starts half the time. Turned out there was a small crack in the positive clamp. Used a small piece of wire to take up the space and it fires up every time now and the battery drain seems to have gone away. Otherwise check your grounds. These cars have a very odd way of grounding, one just to the side of the battery located on the fender well goes bad too. Good luck
