Boat battery

Just curios to see if anyone charges thier boat battery and if so what with, Solar or trickle? 15 years ago I had a 21ft Northshore, with a marine battery, never touched it, motor started first time an all electrics no problem, now I have a 5m Quintrex which I can't get near my shed, because of lots of trees in the way, do I just chance it that the motor (60HP Johnson) will keep the battery up when I go out or charge it some other way. ?

 as long as your motor has a alternator of some sort (and anything over 30hp with electric start should). And you use the boat on a regular basis (once a month) I wouldn't bother with a charger.  the alternator will pump out heaps more amps than you could use on a tinnie.  Just ensure that you have a battery isolator that you you switch off when you get home, but every tinnie should have this anyway.

Agree assuming the battery is in good condition

 Otherwise the CTek is a good investment if the boat sits around for >3months even if it has a good battery.

I just use a solar trickle charge...Only cost a few bucks and it works well just to keep the battery fully charged...

 have you got a regulator on your solar panel , if not you need 1 other wise you will end up cooking your battery , and dont believe the story the panels regulate them self get your self a BP solar regulator easy to hook up and you wont cook your battery you will get twice the life out of it if you use a regulator  pm me if you want any more info

 Yep, that's because under perfect conditions, and that's what we normally have, up to 17 volts can come from a single solar panel, that will kill your battery pretty quick. That's why a regulator is required.

Depends how big the solar panel is , if you buy a small 20 w panel you wont need a regulator and that should be plenty to upkeep your battery they cost between $50 and $100 . We sell them all the time for just this kind of appliction.

Haven't put a charger on either of my batteries in the 4 years I've had the boat.
I just isolate the batteries everytime I get back in, and never had an issue, even after extended periods without use.

I put my battery's on the charger if I am going on a big trip but if its going to be sitting around I generally pull it of the shed and run with the ears on it for an hour or so. Have an isolator that is turned off after each trip and works for me. Cant be buggered stuffing around with the trickle side of things.
