    I am looking for a battery charger for two 12 volt marine batteries that can use both 120 electrical outlet power and solar power to recharge the batteries any suggestions?

    Practical Sailor has any of their complete test reports on line for a small fee.

    Google them , the info is worth the few bucks.

    AVOID "ferroresonant" (older Guest) and other cheap crap, which has killed more batts than they have charged



    You need a DC/Dc regulator and AC/DC Rectifier

    If your going to use both Solar panels and AC shore power or from a Generator you need a DC/Dc regulator and AC/DC Rectifier

    This will do it.


    Model SP5

    Regulated DC/DC and AC/DC rectifier

    110/220 VAC Input

    If you are charging off-boat or do not need weather-proof, you might look at the BC12B Black & Decker. $36 each at WALMART. I bought a pair for use with 2 105A Everlasts for Trolling motor. The charger is 3-stage with Flotation top-up. Seem to be working great.

    They are fan cooled, so I would watch using them in a confined space.



    Big Differance!

    After reading the last two relpies I see that your looking for toys and gizmos. Not real Marine Grade Electrical equip.

    The Samyung Model SP5 Regulated DC/DC and AC/DC rectifier that I mentioned goes for $595.00 here in the USA.

    If you can built one use keyproc(dioda) from welding machine to have a nice cool charger... it is not hard. a small version u can install a automatic stop.
