winter battery storage

[fishaholic18]

Leave them in the boat disconnected or if you have a battery switch, turn it off. As long as they are in a dry spot in the boat, they will be fine. You can charge them if you want, but it isn't necessary.

if left outside and charge goes down battery will freeze and be no good.do as macojo says

If this helps.

I installed an onboard battery charger that I always use at the dock (the batt switch is always off at dock too).
For the winter, the switch is off and I plug into my outside garage outlet and trickle charge all winter. Its auto-charge and drops to like 0.5A once charged.

This way I just leave them connected, check the fluid in the spring and I'm good to go. Never sorry about freezing either.

This is exactly what the boat mechanic at my marina told me. he said " if they are good batteries they will just need a little charge in the Spring. If they are junk they will be dead in the Spring. Better to find out then than when you get it in the water." I have 2 batteries with a switch. When I had the boat winterized they just disconnected both batteries.
