So a timely thread, was wondering if there were any recommended battery tenders/chargers. Will check those out and pick one up. Not much I can do about my commute, and I'd rather have an hour to work out than having to drive my car around extra.

-verts really seem to suffer from this. Maybe more of us have tiny commutes? I bought the CTEK 7002 but the cheaper CTEK or this are fine for trickle charging. Mine can fully charge a flat battery quicker and has a recondition mode that apparently often gets 2->3 years more from dead batteries

Yes, this seems to be epidemic among us low mileage cabrio owners. Mine was 3 years old, 23,000 miles and replaced under warranty the beginning of November. Also had he "unfavorable driver behavior" codes.

Yes, also now a proud owner of a CTEK unit.
If your sport doesn't put blood, dirt or grease under your fingernails,
then it's just a game.
