Best way to charge the battery?
I finally got my generator to recharge my battery on our Scamp 16.
What is the best or fastest way to charge the battery. Should I just plug in the cord from the Scamp to the generator? Or should I charge with a direct cord to the battery from the generator?
And how long does it take to top off a typical deep cell battery using wither the generator or on board charger? I tried to ask this once before and don't believe I got an answer or cannot the thread.

What we have done (successfully) for years is to remove the battery from the unit and take it into our garage where I clean the positive and negative terminals and then place the battery on a battery maintainer till its needed in the spring. Never had a normal 12V battery go down on us yet....!!!

Hi Doug,
I run a C-pap with a 12 volt cord and have gotten 2-3 days out of a deep cell battery. I used it in conjunction with the furnace yesterday and the not so good battery I had went down fast. I would need to run my generator to recharge the battery as fast as possible and wonder if the on board chargers on the Scamps are as fast as direct from generator. My hunch is the generator to battery but wonder if it is a horse a piece.

First, fastest and best are not necessarily the same.
There are a number of variables to consider. Is your deep cycle battery flooded, AGM or gel? AGM batteries for sure require special chargers made to charge AGMs.
" Should I just plug in the cord from the Scamp to the generator?" Are you talking about charging via the converter or using a dedicated charger?"
"should I charge with a direct cord to the battery from the generator?" Unless the generator is set up with a DC charge function, you will need to use a charger to rectify and control the charging.
As to how long it will take to charge the battery, that depends on the battery(ies), there condition, current state of charge and the charger you are using.
What's your setup?

As alluded to, the "Best" and "Fastest" way are going to be different. For "Fast" a direct connection may be fastest IF the DC output of the generator is greater than that in the next idea. But a direct connection can also lead to under charging or overcharging and battery damage.
IMHO, the "Best" way would be to use a quality, "smart" charger connected to the AC output of the generator. This may provide a faster initial charge, as well as protect from overcharging. And "How Long? can't tell with the information provided, i.e. battery condition, state of charge, charging output etc. are all unspecified variables.
But, if you bought one of those economy generators that sounds like a lawnmower when running, what ever it takes may be to long for fellow campers.

The direct connection to generator is typically about 8 amps unregulated.
What is the converter output? If more than 8 amps it will be faster.
Unless you have a top quality upgraded converter, the fastest charge will probably be if you attach a good portable charger. Get a high output portable charger like the VEC1093DBD.
Amazon.com: Black & Decker VEC1093DBD Smart Battery 40/20/10/4 Amp Battery Charger: Automotive
It is 40 amp output at the highest setting.

That's a powerful battery charger that should do both rapid charges as well as have a smart charge feature, and run off of a generator with about a 800-1000 watt capacity, but it is a bit on the pricy side.
Here's a link to the owners manual: http://servicenet.blackanddecker.com...VEC1093DBD.pdf

Best way to charge a battery
The best way to charge a battery with a generator is to throw away the generator and strap a solar panel on the top of the camper. The only thing you can accomplish with a generator is pissing everyone around you off. Generator is only necessary if you are running your AC or electric heater. Otherwise enjoy the peace and quiet and get a solar panel.

Agreed.

Yup....my 100 watt panel keeps the batteries charged....generator for air conditioning.
Oh next weekend I'm heading to NY to mine Herkimer diamonds and they advertise for $5 extra electricity. ...so I asked if it will run a 5000 watt a.c. unit he said no.....can I use my quiet Yamaha generator at night....was told no problem! Psych!

I'm not surprised he said no, 5,000 watts is almost 42 amps and would require a 50 amp connection. I'm pretty sure you mean 5,000 BTU which would probably use less than 800 watts and could easily operate on a 15 amp (1,800 watt) circuit.

Somehow I think that the question should have said "5000 BTU". if only because a "5000 watt" a/c unit would not only would turn an FGRV into a walk in freezer, I doubt if they would be lugging a Yamaha generator big enough to power it.
If they ask the right question, as most 5000 BTU a/c pull <8-10 amps, they should get an okey-dokey for shore power.

Not necessarily Bob...I camped in a different campgrounds in Pa that offer very minimal electricity...enough for my microwave but not enough for the ac unit. They mention in the form you sign no air conditioners to be run off their ac ...generators are fine. A few people up near where the ac lines start might get away with it but on the other side of the camp there would be no power.
Ace of Diamonds Herkimer mine sounds from the feedback a touch ghetto lol but they are supposed to be much friendlier then the koa camp up the road(and a 3rd cheaper)

Cant say for sure Byron as I don't have one in my trailer & can't seem to find a real need for one, but I suspect they are direct relatives of one of them there micro waves that we occasionally hear folks talk about having.

Some campground owners don't like a/c's because they are often run 24/7, playing havoc with their power bill, whereas microwaves just run a few minutes a day. And the generator noise doesn't bother them as they aren't sleeping right next to one.
I have been in campgrounds where power was one price, but adding an a/c raised that price.

Yup but sadly both the ac and the microwaves seem to have a direct relationship to the generator. While the microwave will only run for a few minutes a day it sucks back enough power that one requires the generator to run for an hour to put the power used back into the battery.
Been to a number of campsites in recent years - both public and private and forest service areas were generators are not welcome even on reduced hours of use.

And I will avoid those kind of parks/camps during the summer. Spring and fall I no longer need it....hot humid summers and wintertime different story. I was camping in Pa last weekend and actually fired the heater on for a bit in the morning, it dropped down to 50'. Short runs with the blower fan my solar panel will recover it... running the furnace 24hours straight....need either ac or a generator.
As you can see we have generator haters and lovers. Sometimes for me its just a needed tool. I'm not going to stay home on a weekend just cause its going to be 90+ degree's and real humid. Daytime I can deal with it... night time I want a level of comfort. Hence why we are in campers and not sleeping on the ground staring up at the stars like the cowboys did lol.

Seems like it would make more sense to run the generator for a few minutes while using the microwave...
