Something killing the battery. 2000 Ford Focus.

I have a 2000 ford focus 2.0 split port engine code (P). Ive had the battery replaced several times and aftet 4-5 days the car won't start like the battery is dead give it a jump start and it fires right up... take it and have a battery tester put on it and the volts are good but the CCA have dropped down in to the double digits... put a brand new battery in it and have all the test ran on it (starter, alternator,etc..) they come back fine... a few days later the problem comes back. Can any help me please...

Sounds like a parasitic drain. Here's a good tutorial on how to approach this problem methodically.

Here's what one tech says about that:

"Carefully remove the battery saver relay (labeled in the inside fuse box), and feel for a click from the relay as it is removed. If the relay doesn't click, but the draw goes away when the relay is removed, replace the relay. If the relay does click when removed, further diagnosis of the Generic Electronic Module (GEM) will be necessary."

At that point, a scan tool might be required.

That helped a good bit I read something about it could be the battery saver relay... any thoughts on that
