I have an Odyssey PC680MT. From what I've seen, the dynabatt is based off the Odyssey PC680 (no MT). The MT comes in a metal outer shell to handle heat (engine bay) better and has the terminals. I think I've had mine for about 1 1/2 years, with no ill effects.... except I left the keys in the ignition in the accessory possition... I tried to start the car about 45 mins later and had to jump it. Other than that.. it always fires right up... even in the winters (only gets down to about 36F at night here). I don't have a stero, so I can't comment on the extra draw. My alternator is underdriven though.
