Just a few months ago (right about the 2 year mark) I upgraded my alternator pulley to NST's 10% overdriven one to help the battery recharge better a bit.

In the overall, it works fine. You do have to be more conscientious about battery drain though. If you drain the battery with the engine off (e.g. running the radio a long time, playing with the power windows and seats continuously, leaving the headlights on , etc), you will make the car unstartable until you jump it or recharge it.

Odyssey's OMAX-6A-1B charger is a pretty good investment to go with the PC680. You can install a permanent quick-connect header at the battery (I ran mine through the trunk floor so it's accessible outside the car with the trunk closed) to make it easy to hook up. It's great for maintaining the battery if the car is off a long time, and it knows exactly the charging profiles to use to max out the PC680. Even if I haven't been abusing my battery, I hook it up once every week or two just to let it top off the battery (it does a better job than the alternator does).
