Good trickle charger or not?

First, I have never used a battery maintainer or trickle charger on my TT or boat.

I usually keep the TT at the house and just plug it in every few weeks ( 2014 Apex so should have a decent converter ). It does have a battery cut off switch that I installed. Only thing wired direct is the electric jack, don't know if this would cause a parasitic drain if not being used.

The boat has 2 batteries and I usually pull it and put it on the trailer or lift in Dec, until late March or so. It also has a battery cutoff only thing wired straight is the bilge pump which may be a parasitic drain even if not on?

It seems every year I end up replacing one battery on the boat. Wondering if one of these

would work on either the boat or TT or both. I see no info on voltage the battery would be maintained at.

Any suggestions for a better maintainer for not a lot of bucks? I do have 110 power I can run to the boat but it is about 100 ft and it would be exposed to the elements. Really don't want that, which is the reason the solar caught my eye. TT can be plugged in with TT cord and 20AMP adapter without a longer cord.

    It depends on the actual charging voltage but in general your belief is wrong.

    A tender type automatic battery maintainer is much better than just leaving it sit......for periods more than a month or so.

    And for the OP:
    1.5 watts isn't enough capacity to do much good.
    Something on the order of 15 watts with a "smart" controller is much better.

    Northern Tool has several different models.

    I had one of those, but never had any luck keeping my battery up. I finally got an Ultra Trik-L-Start. It works for me because I can keep my MH plugged in 24/365 at home. (I also changed out my battery killing Magnajunk 7345 for a PD4655V.)


    I use the Trik-L-Start as well. Try this link:

    I keep my MH plugged in 24x7x365. It maintains the chassis battery perfectly. I used the alligator clips and have it hanging by a wire tie in the engine compartment. Functional, but not elegant, installation. It can be hardwired as well.

    A battery in good shape will hold a charge for months as long as all parasitic draws are removed! I believe that keeping a constant charge going is harder on a battery than letting it discharge slightly over several months, then putting back on the charger when being used.
  • I got mine at harbor frgt about 6 bucks use on my boats and MH work great.check your water level plug in and wait for spring.
  • when I clicked on Ultra link, it shows invalid.
    I use the battery tender for my boat and motorcycle.
    I even had a baaad battery, and plugged it in. took about a week, but brought it back. use it as a spare for watching TV

    BoBoo, I just ordered the PD4655. I opted for the 55 instead of 45. how is it working, and how was the replacement
  • I use MinnKota multi stage charger/maintainers on my TT and on my boat. works great.
