I already own the AC version of this Battery Minder, and I use it to keep my car batteries topped off, as well as some deep cycle batteries that I own. The Battery Minder products are very high quality, and this one is no exception. I currently have this hooked up to my 15 watt solar panel, and use it to keep my deep cycle battery topped off. It has worked flawlessly since owning it (30 days now), and keeps the battery on float charge once it is full. If comes with "bullet style terminals" on the unit, but you can easily remove them and add any kind of connection that you want. I personally use and recommend "Power pole" Connectors. They are sexless terminals that can be used for Many different types of DC electrical connections. This charge also comes with a battery temperature sensor monitor to help it better adjust the amount of power it sends to your battery. This particular model will accommodate up to 180watts of power, which translates into 15amps of power to your batteries. One last thing, if you want to get really cleaver, you can plug this unit into a 120volt AC wall outlet, and then use this to charge your batteries from the wall. To do this, simply find an old laptop computer Power Supply cord (previously used to charge your laptop from an AC wall outlet) and modify it to plug into the Battery Minder charger. Every laptop Power Supply is designed to take 120volt of AC from your wall outlet, and convert them into 12volts DC in order to charge the internal battery inside your computer. There is a little black "box" or "brick" that is incorporated with these Power Supply cords, and this is precisely what does the AC to DC conversion. Once you modify the end of the old computer Power Supply, that was designed to plug into your laptop (with a Power Pole connector or something similar), you will then be able to plug the power supply into the wall and take the 120volts of AC power and turn it into 12volts of DC power. This new 12volts of DC power will run through the battery minder, and the battery minder will make sure to regulate the amount of power being sent to your batteries. So basically, you can alter this Battery Minder to run off of Solar Panels, or your 120 volts of AC that come from your wall outlet!
