Winter - batteries question

[Pirate Lady]

Is there any difference between turning the Perko switch to off or actually removing the wires from the battery terminals?
That said, my bilge pumps are hard wired directly to batteries but on land they will not come on, so let’s eliminate that point.

What other items do yo have with constant power? Radio memory? A fuel injected engine? But, it's a minor difference - however removing the negative cable is very quick and easy to do - especially with the easy access you have with your particular model - and then you're guaranteed not to have any draw on the batteries.

For over 20 years I've always left them in place and pulled a cable and never had an issue.

Any way to plug it in? A25’ should have a charger, no?

The marina says in winter contract “any electric left plugged in when you are not actively working on the boat is a fine of $100 per day”.

There you go...'nuff said. Trickle charge them to full capacity, leave the batteries in the trays and disconnect the negative terminal(s). If they are dead in the Spring then they're in need of replacement anyway.

If you are in outdoor storage maybe a small solar panel charger? Maybe one for each battery with them disconnected from the negative on the boat that way if 1 fails it doesn’t take out the other

Sundance's are different uses and needs then sport boats. I'm a sport boat.

I buy dual purpose batteries at Sam's Club. Never take them out, just put a charger on them every 2-3 months. I usually get 3-4 years out of them. When one goes bad, I buy another. That's why you have 2

Now I was runner refrigerators and other stuff, things would be different.
