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...

 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.
