Hello, I want to use this to replace the one in my rv to charge the house battery while the engine is on. can this stay on continuously for 5 hours?

It would be a guess on my part.... I just know I can run 30-35AMPs through it for like 5 to 6 hours and it held nicely while keeping my hydrogen fuel cell powered...

Really depends on the load you are going to place on it. Right? I use this relay to support an Amp load between 30-34 Amps continous for a 5 hour period and it held up well without a whimper. If stopped power for a brief moment to do a quick system check, the relay de-energized and re-energized without an issue. Click-click and off we go...

I would make sure that the cigarette outlet is live when the motorhome is turned off. Otherwise, it should help to keep the battery charged unless you have significant power draws.

yes it can plus,you leave it plugged up all the time when you have it moored or parked on the Trailer. It will keep your Batteries maintained and they will last you much longer.

I have never left it on for that long. I would imagine it would still respond after being left on for 10-20 minutes. As long as you have enough power in your batteries.

You might need 2 of these but what's the reason you want to use this when you have to charge it for 8 to 12 hours and then unplug it and use it until its power wears of an plug it again. It might be useful if you are one that goes out of town and the humidifier working. I use it for my car when I go out of town. Have you checked the Eva-air Petite Electric Dehumidifier? If might be better for bedroom, again depending on your purpose. I have one of the electric. So it is continuous and trips off when the water it collects in its built-in container gets filled.

Ken J was real close. You have to take 80% of the atv battery's AH rating (which, by the way, can be anywhere from 4 AH to 36 AH). You never discharge a lead acid battery 100% (12.0 volts open circuit is discharged, 12.72 and up open circuit is fully charged). They have a very high resistance to recharge when you discharge them completely. So a 5 AH battery has 4 AH available. Drawing 3 amps for one hour is 3 AH. So that battery would only last about an hour and 20 minutes give or take a few. A 36 AH could go over 9 hours. So it ultimately depends on what AH battery you use.

I have a larger battery in my truck and this item will not keep it charged at all times. The charge is too weak. I doubt it can keep up as an on the go charger with 2 batteries......

I have used this battery to power a similar trolling motor on a Native Watercraft Ultimate 16 with 2 adults for 2 consecutive days. I do not know how much power was left so I recharged before the third day. This was not constant use, but it was a significant amount of time running on speed levels 3 and 4 of a 5 speed motor. I have done this several times in both river and bay applications. Hope this helps.

No. Just hook it up directly to the 12volt battery posts. I have owned mine for some time now and it works very well to keep my RV auxilliary battery charged.

I put it on my gooseneck trailer hooked it up to a battery tender to keep my battery charged at all times works good for that. I don't think I would do the house thing.

You might want to consult an electrician on that question. We only use the generator to charge the battery on our rv.

The short answer is "Yes". David Tullos says it will last 8 - 10 hours on full load (1500 watts) but I do not believe it will last any where near that long. The first link I have provided below computes the battery will last .66 hours at a continuous 1500 watt load and that makes sense to me. I have run a 2500 watt inverter on 1 of these 12 volt 100 amp hour batteries. The inverter must be a 12 volt inverter. The question is...how long will the battery last. That depends on the average (a refrigerator for example) or continuous wattage (maybe a 1500 watt heater running continuously) used by the electrical devices being powered. Of course the fridge doesn't run continuously so you have to take that into account. If you run a 1500 watt heater continuously off of this 100 amp hour battery you should be able to compute how long it will last. You also do not want to discharge the battery too much below 50%. There is a certain amount of research you need to do part of which involves using very thick gauge (probably at least 4 awg but maybe as large as 0 awg) cables from the inverter to the battery which your inverter documentation should tell you. The general rule of thumb for DC current is that for every 1 amp of AC current used by an appliance you will draw 10 amps of DC current from the battery. 10 amps of AC current will draw about 100 amps of DC current. Here are some links that might help. I do not know how reliable these are but they seem to be correct with my understanding of electricity and the research I've done. The first link seems to be the simplest to use by plugging in your own data. http://usasolarwind.com/Tools/BET.html http://powerstuff.co.za/battery-size-calculator/ http://www.bdbatteries.com/dcdcsolar.php I hope this helps.

if your battery is low it may take up to 3 0r 4 days since it's a low amp charge and designed to keep the battery at full charge once it's at full charge. This charger is super for use when you don't drive the vehicle a lot and it sits for any length. it can be used on the battery in the car or taken out, once it's on it can stay plugged in all winter of summer just unplug it when you go driving. If the car stays outside they make a waterproof model. If your looking for a fast charger this is not what you want, if you do buy this make sure it's the 12 volt model ... hope this will help you

I've seen some discussions where there was a regulator required for use with solar chargers in some situations. Had the same issue with my lawn tractor; no charge after 8 hours in the sun. But it works fine for other batteries... go figure. May want to ask someone at your cycle shop about how to use this. And the other responders are right, if your battery is stone dead this thing isn't gonna help you. I found a 6A Stanley charger at Lowe's for $25 to use on the lawn tractor.

From my experience I wouldn't attempt to go over an hour. I had three batteries charged and ready at all times. When one would get low I would change it and put the used one on the charger. If you are shooting continuously go AC if you can't use AC keep an eye on your battery level. I hope this is helpful.

Yes, but make Shure you have a good battery and keep your car running, cause if you don't it'll drain it in about an hour

I use mine every night for my cpap machine while we are dry camping. I am able to use it for 3 or 4 nights without recharging the marine battery.
