I happen to have Odyssey batteries in both our Elise and our Seven. Odyssey batteries are "power-AGM" batteries - low-weight, dry batteries.
My charger is a CTEK, model MUS 4.3.
This past Saturday morning, my Elise would not start, even though the CTEK showed green. When I switched the CTEK to the cold weather mode (the snowflake icon), and left it for 24 hours, the Elise started right up. I contacted CTEK Customer Support, and they told me that an AGM battery requires a higher-voltage charge, so it should be set to the cold weather setting, all the time. There is a 'Recondition' setting on my CTEK, but their support group said I should NEVER use 'Recondition' on an AGM battery.
Be sure to know what kind of battery you have, and how to use your charger/reconditioner for that type of battery. Keeping the cars inside, and having the CTEK always connected (in the right mode!) will, I'm sure, extend the useful life of the battery.
