Location: mercer wi | Who keeps boat batteries hooked up to a charger during winter storage. Looking at battery tender jr or the plus. Do you keep cranking and deep cycles both hooked up. Just looking for input on this before I purchase a couple for winter. Pros/cons of both models please |

Location: Minnesota. | When you remove batteries for storage, top them off with distilled water (assuming you have this type), give all of them a full charge (10 amp charger) and store in your garage. Check them every 4-6 wks and top off if needed with the charger.
Good batteries should rarely need anything more. It's worked well for me for over 30 yrs. w/zero issues.
I store them off the cement floor on a well-supported shelf but with the batteries of today I'm not even sure that's needed anymore.

Location: On the water | When I'm finished fishing, I disconnect batteries, top them off with distilled water, charge them up, and leave them in a unheated garage in the boat. I usually don't do anything to them until the first fishing trip. Has worked for years.
Good Luck, Tom |

| I never store my boat (here in Indiana, we often can find open water throughout the winter), but there are times when I don't get out for long stretches.
I have a competing product to the one you referenced, but essentially they do the same thing. I have 3 batteries (1 starter and 2 trolling connected in parallel) that are 5+ years old. So I have 2 as each is only a single bank. I believe it is money well spent.
I also check fluid level and fill if needed, at least once per year.
