I am leaving my 2011 CT 200H for 5-6 months. How should I store it? Disconnect 12V? Put whole system on a trickle charger? It cannot be driven because it will not have tags or insurance.

 

I would make sure the traction battery (the hybrid battery) has a full charge on it. Full bars. Maybe coast down a big hill and coast home and park it.

As fr as the trickle charger for the 12V.. i guess that wouldn't hurt.
