We were talking about the 5 month boating season.
For the seven months off season, I have the boat battery in the basement where I run a 12 v LED clearance light off it and once or maybe twice a month I'll hook up the battery charger to it set at 2 A charging rate.

Good. If you store it in the driveway during the season, it would be good to put a trickle charger
on it. These are some great little chargers, and they'll keep even the big batteries charged:

The ring harness can be attached to the battery and left there for very easy connect and disconnect.
