Standalone Charger for 2 6volt batteries

My trailer has the standard WFCO converter charger, I am buying a couple 6 volt batteries and would like to get a better charger. Is there a decent stand alone smart charger that is cost efficient? Eventually I will add a Progressive Dynamics 4 stage converter charger but was hoping there would be a cost effective stand alone that would eventually be my garage charger in the meantime.

I just ran across this charger, SOLAR Pro-Logix PL2520 6/12V Battery Charger/Maintainer with Boost - 20 Amp. I think it would do what you need until you up upgrade your converter and then be your garage charger. found it on the big A, I'm not sure were allowed to post links??

I had a bad converter in a TT and used this to get by. Now is a general use charger in my workshop.

Most of the WFCO's are at least a 3-stage charger. Maybe not as long-lasting as some other brands, but a decent unit as far as performance.

Are you looking for a maintenance charger to keep the batts tuned up, or something that is suitable for re-charging a substantially depleted battery, e.g. one at 50% charge?

Note that when you put two 6v's in series, you use a 12v charger. Don't need anything special for 6v's unless you want to charge them separately.

Battery Minder has good models in various sizes.

I've also had good success w Batty Minders but they are relatively lo Amps. Just added a 2-4-8A unit to use as a maintainer for house bank of 8-6V GCs while in storage. Even that won't doo much as a basic charger if battys are down significantly.

I have a ProMariner in the boat and ir is a qualty multi stage and they come in multibank units if needed.

Well I guess I need to figure out what model mine has. It will lose some efficiency with the 20 foot wire run from the converter to the batteries but maybe not so much as I think. Bulk charging is the goal. Need to charge 2 6volts each day and since it will be close to freezing each night I imagine the batts will be pretty low. This is for a planned trip in May to Bryce, Yosemite, Zion, Sequoia etc. If the generator doesn't like the high elevation we may have to really conserve power but it should be a great adventure. Just trying to minimize the number of charging hours so we are not tied to the campground all day.

I put a Powermax 55 charger in my MH. Mount it near the batteries and plug it in.

You can run both as long as the batteries don't boil.

Loss will be insignificant if the wire is adequately sized (bigger gauge). At least #10 wire if you expect charging in the 20A-30A range (about the max your pair of batteries can accept).

Progressive Dynamics 9180 R (Refurb) is 230 dollars plus 18 S*&H direct from Marshall Michigan (Progressive dynamics) you also need to spend aroudn 30 more on the Charge Wizard.. Or Price a 9200. .NOTE that is the 80 amp model.. I know the price.. .Cause I just replaced one that died.

That is not a bad price
The charger I used while waiting to leave for Marshall (Dang thign died on a Sunday Or at least that's when I noticed, so no chance of getting a replacement then, had to get what I could) Was a Deltran Battery Tender, the big one, with 20 amp Boost and 70 AMp Jump start. It did the job for me and a few more after that Came in rather handy during my semi-annual 800 mile hike.

But the first stop on that hike was Marshall Mi for a new 9180R.

THe Battery Tender was about 100 bucks at Auto Zone.. But for what it does, Worth it.

Why not just replace the lower section with a 3/4 stage changer?

It has a WFCO 8955 3 stage charger converter. I installed the new batteries this weekend and was charging them for awhile. I never saw bulk charging which should be 14.4 volts but I got 13.5 for a couple hours which should be about right for absorption mode. The book says 13.6 so if my Fluke meter is accurate there is a .1 volt loss between the charger and battery. I can live with that. The new batteries were at about 90% charge so not deeply discharged enough to go into bulk charging evidently. My WFCO owners manual does not say what voltage triggers the bulk charge, just that it has a 4 hour max time before switching to absorption mode.

In the next few days I will try running the furnace for a day or 2 to get hem low enough to kick in bulk charging to verify that it actually works. All in all I am pretty happy with it, should have read the manual before reading all the WFCO bashing threads. I am sure there are better chargers out there but considering the cost of new batteries it probably is not worth the upgrade if they last more than 4 years.
