Location: Racine, Wi | I leave mine in the boat in the winter as well. Just make sure they are fully charged and plug the charger in throughout the winter. I usually fish a few times during the winter so this helps me to keep them charged anyway.
I'm not sure if you should keep the charger on them all winter unless you have a trickle charger. Once it's fully charged, you should be okay, then just a charge to ensure it's still fully charged once in a while should be okay.
DISCLAIMER: I have no idea what I'm talking about, so take that for what it's worth. LOL I'm sure a more highly knowledgable battery guy will pipe in here. |
