Just take the boat to florida during the winter and use it, that way the batteries are always charged

Part #SPP1 from Napa Auto Parts. 10 bank trickle charger maintainer, should be able to pick one up for around $200.

battery tender makes a bunch of multi’s even a 10 bank, but those get expensive. I’d recommend getting a tender like I posted or getting a single and alternating them. They shut off when fully charged and never damage batteries. I leave my car on one all year long.

Battery tender made in Deland FL my home town is junk. For three years I used it and replaced my batteries every year. Sulfated 3 sets of batteries over three years. Returned to owner at battery tender and he stated impossible, smart charger!.
Showed him sulfated batteries and he still disagreed. BS. Tossed the junk back to him and told him I will ****can all there products. Three years later same set of batteries and still work fine. No tender!. Leave batteries flat and your golden, obviously avoid storage in cold places for winter.
My 2 cents of battery tender, junk!.

I always have just took the boat battery out and put it in the warm garage. I know 12 is a lot of battery’s, but think of it this way, 12 is a lot of battery’s to buy at the start of the season. We all know battery’s do not like cold weather.

Between all the boats, I have 15 batteries. It always seems like I am buying a battery, but once I look at it, I typically get at least 5 years out of most, if not more. Year around, I keep all batteries on a computerized charger/maintainer. Whenever I leave, they get plugged in. At LOTO I never take them out of the boat, even in winter. On boats with multiple batteries, I use a 2 or 3 bank charger/maintainer as found in bass boats.
