If it's generally cold, you can safely charge the batteries fully through whatever means is convenient and disconnect them entirely and they will easily survive the winter without self-discharging overly much. If they are dead in the spring, they were already on their last legs.
This is not a good idea if the temperatures are warm. The rate of self-discharge is quite temperature dependent; a few weeks at 90° is worse than several months at 10°.
