    I guess I’ll be using this charger to keep the batteries charged in the Winter and look for a bigger one for the boat. Any suggestions on size or brand?

    Need some info first; What and how many batteries do you have? Parallel or serial (or both) banks?

    I have 14 (was 16) batteries on our boat making 5 banks.
    Three, 40 amp chargers and 200A available from the inverter.
    It's just a lil 58 footer.

    It like when the submarine races are over and your ready to take your date home,,, Click ,, click ,, Uh Oh .. :(
    Always have strong batteries on board. o_O

    I just have 2 batteries that are used to start the engines and as house batteries. I assume they’re in parallel. There is a battery switch that has 1-2-both-off.

    For a boat your size assuming you now have LEDs instead of halogens, 20 amp should be fine.

    personally I like the Pro Mariner Pronautics. I have two on my 53, both 30 amps, one 24v (edited) for the house bank and a 12v for the engines and gen. They re compact and smart multistage.

    I ve always had good luck with ProMariner. I also have a 4 bank on my electric sailboat and have used them on boats I run incl the 110 Lazzara.

    One battery each engine for starting? Two total in the boat?
    That switch is probably for the house and combining the batteries if needed.

    I agree with brother Pascal that 20 could do it, I'd still lean back to at least 30.
    12V systems eat up Watts quickly.

    Pascal is correct on the later ProMariner units, good stuff.
    I used to sell MasterVolt and Victron with great results.
    Just stay away from Xantrex.

    Did you ever figure out where that third lead went to?

    I didn't follow it but it wasn't connected inside the charger unit. It was just wrapped in electrical wire. I think they might have made their wiring harnesses with the 3rd wire in case the customer added the generator. Or maybe there was an option for a 3rd battery.

    You may even consider a third battery for the house and accessories.
    Don't limit your self to just a 2 channel charger if you have ANY plans to improve your ships DCv systems.

    Probably would, but if your charger is in a dry location you might compare against their 3-bank ProNauticP series.

    Depending on in-place wire sizes, you could maybe go higher than 20A... at least back to your 30A original and maybe slightly higher than that... and that could give you higher/faster charge rates and/or capability to charge/maintain a third bank too (genset or separate house-specific, etc.). Decent programming, so you don't have to mess with turning it off when you leave the boat. The ProNauticP series also includes some remote monitoring capability.

    Thanks for the info. I've started researching a bit more and I'm looking hard at the ProMariner 44020 ProSport HD Waterproof Marine Battery Charger, 20 Amp, 2 Bank. It's only $185 and a lot cheaper than the ProNauticP series. The 44020 doesn't have all the capabilities of the P series but it's less than 1/2 the price. I'm sure I won't be adding a 3rd battery or generator so the 3rd bank isn't important to me.

    Thanks again.

    Just to follow up, I did end up buying the ProMariner 44020 20A 2 bank charger for $185. The best bang for my buck. I like the fact that it has what they call "distribution on demand" so it can push up to 20A on 1 of the banks, if not needed at the time by the 2nd bank. I doubt if my 30-year old charger ever had that capability. I'll take out the 5A unit and use it to keep the batteries charged in my garage during the Winter.

    Thanks again everyone for all the helpful advice. It's appreciated.

    Final Update

    Well, in case anyone is interested, here's my final solution. I went with a ProMariner ProSport HD20 - a 20A 2 bank charger. It has "distribution on demand" so it can put all 20A to one battery, if needed. Physically, it's about 4 times larger than the Noco Genius I replaced. I'll be using the Noco for my battery maintainer when I take out the batteries for storage this winter.

    Thanks for all the help and info from everyone. I appreciate it.
