Have you checked what charge the battery is getting with the engine running? (Idle and 2,000 rpm) it maybe over charging and cooking the battery - this happened to me once, the new alternator i bought was faulty.

hope this helps

Just to be sure: the battery goes flat after a few hours of driving, not just from sitting?

Then I'd indeed check the charging voltage, should be 13.9V-ish.
