1991 prelude 2.1L 109K mi. Had dead battery two weeks ago, charged it, started it (everything runs great once started). took to Auto Zone, battery and alternator both tested good. Battery fully charged (on charger) then went dead again after two weeks. absolutely no problems when running no service lights etc. Seems like the battery is not charging and draining slowly from day to day from starting. Does not seem like any short that is draining the battery while it sits.

Thoughts and ideas greatly appreciated.

1st thing run away from the Zone and have your car checked by a mechanic. It sounds like you have a bad alternator. It has probably ruined your battery. the only thing I buy from the zone is what I can pour from a bottle. Good luck
