I am solar clueless so I wanted to know if I connected these to my deep cycle marine 12 volt batteries would it recharge them? How long does it take?

That is a common question without a simple answer. Please contact us to go over your usage and we can help you specify the proper DuraVolt.

The Goal Zero line of solar panels all have special connectors. While they all play well, with each other, they aren't able to connect to generic batteries and devices without adapters. Fortunately, you can make your own, if you're handy. Or, you can order the adapters online. As far as charging batteries, they will "trickle charge" However, if you want to charge a 50ah (600 watts of power) battery with a Nomad 27 (27 watts), that would take over 22 hours (600 watts divided by 27 watts from the panel) of sunlight to fully charge a dead battery.

These batteries are made for performance, not duration. I use these in my dive lights and I expect about 3 hours out of 2 batteries. If you use these nightly for 10 minutes, a month would be about 5 hours of use. I would say they are giving you pretty good performance.

Hi ! They recharge once they are back on the base. Just make sure you have the D size batteries in the base.

You should be using a deep cycle Marine/RV battery. I'm using these on my travel trailer and they work great with good sun exposure.

Go to walmart and buy a deep cycle marine battery, walmart has the cheapest batteries and they work just fine if you keep them charged and maintained.

I use this solar panel to charge two 12V batteries connected in series to produce 24V. my boat has two 12V batteries, but they are connected in parallel which is likely the case for your boat. Also, I believe that you should be looking for a 12V Solar panel, not 24V. Hope this helps.

My own personal experience was that the FIRST time I recharged them it took a longer than expected time -- almost three hours. After that it took roughly two, depending on how depleted the charge was. (It is okay to "top them off", unlike rechargeable AA batteries.) Yes, the light does change when it is finished charging.Hope that is the information you need.

I don't think the solar batteries can be recharged that way but I'm not sure.Maybe contact the battery company and ask them.

Not sure, but they work with Voltaic's batteries. If the solar panel for the goal zero 21005 provides something like 18V when fully illuminated then it should work fine. Might need to make sure the that barrel jack is the right size.

Good question. I would ask the manufacturer I had a question of them once and they were fairly prompt in answering. With mine I only need to connect to the batteries on my pick up camper and charge away!

I'm no expert but they seem to work fine on our Polaris. 12v is 12v and the charge holds just fine for us. 2 hours or so of steady play.You do need to either save and convert the old connector or make one yourself. The batteries have a simple M-F connection and charge on my basic charger just fine.

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.

Absolutely! I use them on both of my Florida vehicles and they start right up after 6 months. I hook up both boat batteries for 3 days after I return from Florida and they are good to go. Units work great.

I have used this to keep a 12 volt marine battery fully charged all summer and it worked well. I used a charge controller between the solar panel and the battery. This is the one I used.AGPtek® 30A Solar Panel Power Battery Charge Controller / Regulator 12V / 24V 30 Amp with PWM Type of Charging (Automatic Lighting Control + Time Functions). Of course, you can use any charge controller.

Yes, I keep them hooked up to 3 batteries that power my trolling motor on my boat. They do a wonderful job and while sloppier, have lasted much better than those "boat" battery charging units that coast enough to buy ten of these. I keep three of these hooked up all the time.

I believe it all depends on how much draw you are going to have. I connected two of these batteries to an old farmhouse's electric system via an invertor and basically ran lights (mostly LEDs) and charged my laptop, cell, ran a radio or two. My solar panels only produce 120 watts. I never had the batteries completely drained or even close to that and they worked fine. I would prefer to have more than two in the future so as to have more reserve when cloudy periods are extensive.Hope this helps!
