My C&C 32 has two new Group 27 batteries and a 3rd Group 24 battery. They are
all kept full charged via Charles Charger at the slip.
As we're hauling today, I'm wondering if I should lug them home. Will they lose
appreciable lifespan if I let them stay aboard for the winter. The boat plugs
back in mid March. What's deal on real world damage to charged batteries over a
cold 4-5 month span?

Thanks,

RB
