Can you use 12V for emergency power?
A charging current of 8 amps is available in 12V output. Though the battery voltage can fluctuate and isn’t suitable to charge the batteries adequately, you can utilize DC power of 12V for emergency purposes.
How to tell if a battery is fully charged?
To avoid being fooled by the surface charge that’s present on a freshly charged battery, you’ll need to stick a good, heavy load on it for a minute or two, shut off the load, and then test the voltage. A fully charged, 12-volt “flooded acid” battery reads 12.6 volts. If you’re close to that, it shouldn’t be a problem to stop charging. Batteries are very receptive to charging when they are deeply discharged, but the closer they get to “full,” the harder it is to pump current into them. Some RVers figure once they’ve hit the 12.5-and something mark, they’re good enough to go.
How many amps does a portable generator pump?
Other portable generators offer a greater low-voltage output, perhaps pumping out 8 or 10 amps. Here’s where a bit of caution needs to be exercised. Check your generator manual to determine if this is a regulated, tapered output, or simply an unregulated “constant amperage” output. This is important. When batteries are low, a big fat bulk charge is not a problem, but when batteries get close to their capacity, they can be overcharged.
What do RV batteries do?
Batteries are the heart of your RV electrical system. They keep the lights on, the control boards in many appliances operating, and turn the pump over so you can take a shower. We may not think much about them, particularly when hooked up to shore power, with a converter keeping up with the low-voltage needs. But step away from shore utilities and head out for a session of boondocking, and you’ll soon know if your batteries are staying happy.
Can a portable generator produce clean electricity?
Many portable generators, particularly the “contractor” style, do not produce “clean” electricity. A few spikes here and there, a lot of electrical “noise,” can raise Cain with sensitive converter-chargers. If using a portable generator, the purest (and safest) electricity available will come from a pure sine-wave system. Check out Honda or Yamaha portable inverter generators as an example of something that won’t eat your electronics. If your rig has a built-in “genset” like an Onan or similar, your electricity should be clean and fully edible for a fancy (expensive) converter-charger.
Can you remove jewelry from a converter?
Unless you’ve got one of the sophisticated converter-chargers mentioned earlier, the output from the converter is so low as to be almost useless. The usual precautions apply: When fiddling around with even low-voltage systems, it’s always best to remove your jewelry, including rings and watches.
Can a portable generator be hooked up to a battery?
Many portable generators have a “12-volt” output, and yes, this can be hooked up to the house battery system. The issue is the output. If the generator offers a low-ball output (we’ve seen some that offer a 3-amp output), you’ll be running through a lot of generator fuel to catch up on your power needs.
What is the best way to charge a battery in an RV?
Best solution: A fully automatic 3-stage battery charger can charge the batteries faster and improve their performance and lifespan. It’s also available in some modern RVs, and you can also buy an aftermarket model and install it in your RV.
How to charge deep cycle batteries?

Why is my battery terminal coated with corrosion?
The terminal contacts might be coated with corrosion; the battery might have lost the capability to hold charges, or there could be an issue with the charger or the generator outlets.
How many volts does a 12V generator produce?
It’s is mainly intended to provide DC current for running 12-volt devices directly from the generator. It produces unregulated 13.6 volts, which drop when the generator is under load, to around 12.6 volts or even less. The output is, however, enough for running 12-volts lights and equipment to full charge. Why?
How long does it take to charge a 100 amp battery?
The DC outlet produces about 8-amps and 13.6 volts of power, too low for full or speedy battery charging. It might take six or more hours to charge a 100-amp-hour deep cycle battery half. And from there, the charging reduces progressively, and it might take over 24 hours to reach 70% and multiple days for a full charge.
What type of batteries do boats use?
Many marines, automotive and boats, recreational campers and trucks use deep cycle batteries. They provide reliable, high-capacity power compared to standard batteries. That allows owners to enjoy the charge for a more extended period before the subsequent recharging.
Can you cut down the voltage when charging a battery?
And since you’re charging directly, there is no way to cut down the charging voltage when the battery is nearly complete.
Why does the current decrease when a battery is fully charged?
Because heat rises with resistance, the current is decreased to prevent excess heat.
What is the absorption stage of a battery?
The Absorption stage, (the remaining 20%, approximately) has the charger holding the voltage at the charger's absorption voltage (between 14.1 VDC and 14.8 VDC, depending on charger set points) and decreasing the current until the battery is fully charged. This is because as the battery becomes more fully charge, its internal resistance rises and thus requires that much voltage (voltage is pressure, like water pressure, only amp pressure) to push the remaining amps into the battery. Because heat rises with resistance, the current is decreased to prevent excess heat.
Can you charge a gel battery with a charger?
The reason is says no to gel type batteries is that gel batteries require very specific voltages that are lower than that of wet and AGM batteries, and they are highly dependent on battery temperature, so a controlled, temperature-compensated charger should be used for those. More than a couple of tenths of a volt too low and it'll never, ever charge, and more than a couple too high and you'll fry the battery.
Can you charge 12 volt batteries with a 12 volt outlet?
The 12-volt outlet on a generator is for running 12-volt loads, not for charging 12-volt batteries. It'll work in a pinch for wet (and some AGM) batteries, but it's not the most efficient way to charge batteries. You can run a 40-50 amp charger off the AC outlet much more efficiently. The 8.3 amps won't even be 8.3 amps, it'll be more like 5.
Is 12 volt good for AGM batteries?
Now you know there's "good" and then there's "good" when it comes to 12-volt outlets. A "good" 12 volt outlet isn't very good at all for charging an AGM battery. You can use it to throw a few amps into the battery in a pinch (although at about 5 amps it really won't be much), but you'll want to make sure it's properly and fully charged regularly (like every week).
