Trickle charger for winter storage

I have three lead acid batteries on our 1979 sabre 34. Typically over the winter (at least for the seven years I have owned the boat) I put them on a trickle charger from early November to early May. I also top off with distilled water if necessary. Is this the best winterstorage method? I am slowly working my way through the book "The 12-volt Bible" and he mentioned somewhere not to do this but I can't find the statement again and cannot find an explanation as to why a trickle charger is bad; but I haven't finished the book, either nor understand it completely??? During the sailing season we run a solar powered Battery Minder that desulphantes and charges.

So, do I run the trickle charger? What do others do?

I have three x 105Ah batteries in parallel and use a three stage charger that has a float charge as the last stage.

This keeps the batteries topped up without over-charging them and requires very little adding to the electrolyte.

When this is not in use, the small solar panel changing through a controller does the same thing.

Re: Trickle charger for winter storage

Costco is selling a multi-stage smart charger (Battery Tender brand) for $29 (or maybe $39, can't remember for sure). Only 1.25 amps, and not permanently installed (although it comes with ring lugs and a plug, so you don't have to use the spring clips). Would seem to be just the ticket for winter storage.

Same as this one:

I've used Battery Tenders for several years now that I learned the hard way about Trickle charges. They can and do ruin batteries. Get a good tender that does not over charge.

Re: Trickle charger for winter storage

I have a Xantrex 2 bank smart charger permanently installed. It is on whenever I am on shore power, including over the winter. My batteries are 8 years old and going strong.

Re: Trickle charger for winter storage

Historically trickle charging was low constant current without voltage regulation. Today the term is muddy and old school trickle chargers are rare. Today's "trickle chargers" are both constant current "CC" and constant voltage "CV" to protect the battery.

Battery Tender is a reputable brand..
