Battery maintenance

Hello. Just bought a 92 Ski Brendella (Shortline Comp), had it serviced including two new batteries - a starting and a deep cycle. I'd really like to make them last, so my question is during the summer if I'm taking it out several times/week, should I be charging them in between? with a trickle charger?

Thanks for any tips you can provide !

I always put them on a the charger when I’m not using the boat. Battery tender or the promariner prosport charger.

Unlikely the main cranking would need charging between trips, but for house, depends on how its going to be used. If you will be spending long hours at anchor, then a short rid back to ramp/slip, then yes, it might benefit from an on-board charger between trips. For the off season, defenitely keep them on an on-board charger.

it definitely wont hurt to have them on a trickle while not being used

ive had great luck with these on various cars that sit for long periods, and over the winter on our boat batteries
$20-30 on amazon and just set it and forget

Trickle is a non-stop process. You'll get less out of your battery. Trickle is slow and chronic death when used as a primary source for battery maintenance. Your call.

I recommend and use exclusively the NOCO Genius battery maintainer with a micro-chip processor. With a dual setup, I separate the batteries with the control switch (off) and charge each battery with dedicated charger(s) each. It's plug and play and I never get in the boat after I get home to touch a battery. All right there on the shelf.

Amazon here

I also recommend the extension cord(s) if you are leaving the charger on the shelf (not onboard) and merely plug into the attached pigtail.

Each to their own....

$0.02

Battery Tender. My Optima boat batteries ($200 each) spend all winter connected. My John Deere mower battery is 14 years old. It is on a Tender always (other than when mowing). Best $50 you will spend.

Scott62...totally agree with you. I tender all my batteries and have noticed the extension of battery life.

I have moved on to small solar chargers for my boat and jet skis. Trickle charge during the day, relax at night.

Harbor Freight has them under $15.

Thanks everyone - I ended up getting a battery maintainer from Harbor freight ($30). It charges until normal, then maintains it - just plug it in and leave it.
So far, so good.
