How much charge would this give a nearly depleated 12 volt deep cycle volt battery over 6 hours of direct Florida Sun?

I am not sure if it would charge completely. This is more of a battery maintainer when used with the amperage reducer that came with mine.

In perfect conditions, that's 20W/Hour or 1.6 A/hr. or 10 amps total. (approximate values)

The quick simple answer is "not enough". A nearly depleted deep cycle battery may or may not be able to recover with this panel. If the battery was damaged slightly by a quick discharge, it may have more internal leakage than can be overcome by a one amp charge (the practical limit of this unit). This unit is more for maintenance than recovery.

Hey Edwars O. Not sure. What type/sort of system are you putting together? 6V 12V? What are you needing to run, and for how long? What are your energy needs? I can't answer your question my friend without more info. I personally use the 400 watt system with another 100 watt panel. I match my batt bank so every 100 watt of solar for 100Ah of storage. Yes, it is over kill for just myself! I'm still in the learning processes if you will. The panels that come with this kit have zero issues with charging the batteries on cloudy days. I'm very happy with this basic system so far!!

yes the voltage output will vary with the amount of sunlight. I have my panels setup to produce a max of 36 vdc charging a 12 vdc battery bank. your charge controller needs to match your projected final system capacity, if there is a possibility of adding on later. I have a mix of 144s and 88s

This is not designed to charge anything that big. It would take 48 hours of full sunlight (4~5 days in the sun) to get a full charge and that's with it completely shut down. This works best for lower powered devices such as hand held GPS units that use x2 AA, small mp3 players, older cell phones (not a smart phone or anything with a large backlit display).

Not very much, I ran on one 12 volt deep cycle for 24 hours but was only 65 degrees outside, I can give you a better answer in a week when home, great unit

I'm not going to lie you I have never even got mine to solar charge 25% of the internal battery that it has. Could get the LED lights to move from 75% to 100% in a whole day in the sun that was 10 hours. And it doesn't even charge my Dell laptop just runs off of it when u have it ONLY in power saving mode.

Remember that you are pushing amps back into the battery, and with normal losses this 5.3A panel and charger will likely give you 4.5 amps per hour at the battery in good to excellent lighting conditions (that's what I'm getting here in central Indiana). In a day, consider that you'll have 6 hours of bright sunlight, and another 4-6 of indirect sunlight. Conservatively that's about 8 hours of (8 hours x 5 amps) or 36 to 40 Amp-hours restored. That's enough to restore your 85 Ah battery each day if you take it down to 60%. This system should be fine for your battery--and others might point out I'm being very conservative. Even in late afternoon in indirect light I'm getting 4+ amps. You may find a fully-recharged battery each day by mid-afternoon.

should work fine off a battery and using this to keep it charged.. shouldn't used it directly because of voltage fluctuations with clouds and weather.. will put out up to 6 amps in good sunlight...

It will more than likely work *IF* the accessory plug is hot with the ignition off, and the placement of the panel gets good sun for at least 1/2 of the day. 2.4W at 13.8V (or so) is only about 175 mA that will certainly NOT blow a fuse, but will trickle maintain an automotive battery if in good condition. I don't say 'trickle charge' since 175 mA isn't quite enough to expect that kind of result. I have mine in my camper facing East and the 2 year old battery is still fully charged after sitting for 3 months so far.

No real suggestion. I presume 12 volt car battery. Possible poor connection? Current should be less than 12 amps. Mine stays bright for hours (should get > 100 from deep cycle marine battery).

If I had it to do all over again I would probably buy something better. Batt is probably 1600 and the solar panel puts out 1.5 watts per hour. Took 2 weeks for solar panel to charge internal batt in the window sill, direct sunlight in summertime.

Yes,, just be sure you have them hooked up correctly.. I have 2 -12 volt deep cycle batteries and 2 6 volt good cart batteries hooked up to my panels via the controller. The Sun force charger drew moisture and burned out. I replaced it with a Thunderbolt controller. It has a digital readout which is far superior to the simple/confusing light system on the Sun force controller. Also it was only $30-$5 shipping and I received it in 2 days.

Really depends on the size of the battery. It puts out 1.8 amps, so if nothing else is pulling it down , it should charge in a day of direct sunlight.

I use two of these in parallel to charge a Marine deep cycle battery. With a 20-amp charge controller this setup works great for my location, providing about 10-hours of lighting on nights after sunny days, less on overcast days.

Approximately 6 hours in direct, full sunlight. Try to keep the panels at the proper angle by adjusting panels in relationship to the sun for maximum charging of the battery.

Hey race walker, just about anywhere. I installed my panels on a motorhome that has been using two 12 volt 200 amp hr deep cycle batteries wired in parallel without solar. For the last 6 years I have used two GC-2 240 amp hr 6 volt golf cart batteries wired in series. I have always used this rule, get the newest, heaviest batteries that you can afford. In my case I have been served best by 6 volts golf cart batteries in series since my system is 12volts. Hope this helps

4 AA 2500mAh batteries in 5 hours so 4 x2000 in 4 hours or 500 ma per hour. Won't make any difference what your charging source is, it only draws 500 ma
