Hi,
Does anyone have experience of using solar trickle chargers to keep boat
batteries healthy?
I'd be interested in any recommendations/ones to avoid/don't bother
opinions.
I'm looking at keeping 2x110ah batteries happy over the winter - possible?

Cheers, Bramblestick

The bigger the panel (more output) the better. Do not bother with these
little tiny plug in a fag lighter trickle charge solar panels.
I have used a 15w output solar panel on my battery for 3 years now, the
battery keeps pretty much 100% ready to go.
The solar panel I have is at least 6 years old, so I am sure the more upto
date ones would be much better.
Make sure that you use a charge controller with them as well.

Thanks for that - encouraging to know that they do actually work! What kit
are you using?
Cheers,

The solar panel I use is rated at 15w no idea who's make it is though, but
its a pretty old one, so I am sure that a more upto date one would be
smaller in size and more efficient than the one I have.
Maplins do a 15W panel for about £60 these days.
The charge regulator i use came from Maplins its a ACCU the part number is
N82AU about £12.
This set up has worked very well for me.
I will see if I can find a makers name on the solar panel next time I'm down
the boat yard.

I use one of those "little tiny plug in a fag lighter trickle charge solar
panels" and they work really well. I always return to a fully charged
battery, even through the winter. Paid £7.99 on line a couple of years
ago.

I just uploaded my solar boat project. I will add a video with the details in a
week or so.

I hope this will help anyone looking to do the same.
