is the 5w solar charger sufficient for my deep cell boat battery &amp;will it charge up in a weeks time from about 60 percent charge

Highly doubtful! This product "maintains" the charge. If you have good sun, you might get a 1% increase in a week. But you have a ceiling - I do not think it will get to 65% even if you leave it out a few months.

If you fully charge the solar charger with a USB port Ajax of time the battery works great. It will fully a dead iphone 5 battery in a couple of hours. The battery will stop have enough reserve to recharge a second iPhone 5 to about 80%. The battery is great. The problem I had was with the solar panel. The panel will not recharge the battery.

Yes. I've had this system on my cabin for several months with no problems. I charge a deep cell boat battery and my 12 volt light system in the cabin works great.

Hello;In response to your question. Yes, the charger will work quite well for the Deep cycle battery. I use it on my Marine trolling batteries that draw down to nothing all the time. It works great!Jim

Yes this charger works fine for deep cycle marine batteries. I charge my deep cycles all the time with this charger.

look at it like this . a regular battery charger has a lot of power. a nice powerful solar cell will hardly light up a flash light bulb. the only way a solar cell is going to charge a battery is over a long length of time as a trickle charge. the trickle is relatively so small that it really does not matter if you put 12 or 24 volts on the battery. it's still a trickle. i put six solar cells (powerfull ones) on one battery. it charges faster but there is really just not enough power to fry a car battery. just make sure your diodes are good so that the battery will not discharge over night. the answer is yes though, and the more the better, and forget v. & i. regulators unless you have a yard full of cells again you are not generating that much power, probably, if you are like me. - i like all paralel at 12 v. though. i have no need of a 24 v. source.

Depends on what rate you have the charger sent at. The lower the amps the longer it will take, I suggest checking the voltage after 5hrs, should be 12.5 or higher when fully charged for a new battery.

I am using a 10w on my deep cycle battery on my boat. It keeps it fully charged after a few day of sitting in the driveway.

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.

I use two 6 volt trojan T105 in series for the house bank of my sail boat. I have minimal power requirements apart from powering my refrigeration system. The 200 W kit from Renogy seems to do the job quite well keeping the battery bank charged.

This battery is a bear. On a slow trickle it takes about a week with a 1.5amp battery tender. I think that any slow charging is good, but I would be hesitant to have solar be my primary source. I have toyed with the idea of getting a panel, but usually don't stay out long enough to justify it. These are great batteries though. I have two in parallel, and they go for days with about five years on them.

The wall wart is the size you described. No its not a smart charger. This is not a LiOn battery. This is a run of the mill sealed lead acid battery. It puts out 400ma on a 7ah battery and takes days to fully charge. I wouldn't be to concerned with overcharging. I would be more concerned with to much of a drain for the charger or the 5 watt solar panel that is intended for this unit. With no solar or charging, the battery will last about 30 days transmitting a few dozen pictures a day with little downloading. And yes, the wall wart is 115ac with no adapter. If its different, this is literally a $2 charger.

I have 14 115ah deep cycle batteries powering a small off grid house. On a sunny day the solar system will fully charge the batteries. I will soon be adding a 400 watt wind turbine to help on cloudy days.

Repoleved pretty much answered the question. It depends on how much you use the battery and how much you drain down the charge. Mine runs a circulation pump for my solar water heater. I have a 12 boat (deep cycle) and it always seems to keep it charged up. When my panel arrived it had a cold solder joint and I had to re solder it to make a good connection, and you need to figure out how to mount it.

I'm not entirely sure, but the total charging output for two batteries is 10 amps. I would say a generator output of 1150 watts (amps times voltage = watts) would be needed. The on-line manual may show a more specific information. I don't have easy access to my manual right now since it's with my boat which is in storage right now. I will say that at full charge to both batteries, the unit does get very warm, thus the large heat sink fins built into the case. This is a well built, solid unit. I have had no problems with it. I hope this helps.

A very yes, but do not get in a hurry. Also make sure your battery is not so out of date, and a build up of sulfate. This is a smart charger, and the LED says no, do not do it! Also, note that a cranking battery that is often deep discharged or not used on a regular basis will die before it's time. WA4MUC

I use my solar charger in a boat to keep the automatic bilge running. The only thing I can comment upon is low light. I do know that the charger is not sufficient to keep my boat batteries charged if I put the boat on a trailer and keep it in an unenclosed carport. The carport is open on both ends (North and South) and on the West side as well. Evidently not enough sun light gets in to sufficiently charge the boats batteries while the boat is parked in the carport. There are some shade trees around the carport also that may be contributing to the issue.
