Can this be used on the 2 amp setting as a trickle charger to maintain a 12v car battery on a car that is not used for months at a time?

Yep. http://www.batterychargers.com/ProductDetail.aspx?ProductName=94026805ACP As the float a.k.a. trickle charge is very low current, it's best to disconnect the battery from the car when it isn't driven for extended periods.

If you're going to have a battery not used for months at a time then disconnect it. I don't think this charger would be good as a trickle charger. The smart charging features I think would be too aggressive for long durations even on a 2A setting. I've kept it plugged in overnight to charge it and I think it only works well for something like that because of the frequency with which it monitors the battery. I would hope a trickle charger would only need to kick on every couple of hours or even days. This thing will monitor the charge every second and can even sometimes fully cycle the battery due to glitches in the smart charger. I've put a minor drained 12v battery of 10v and it wanted to deep cycle it. You can manually bypass that. Maybe now you can see why a trickle charge wouldn't be a good idea. This is an excellent recharger for any home (an I love it for what it's meant to do) but a trickle charger no.

The manual says that it will not overcharge a battery, but I do not know if it cuts off and then comes back on if the battery charge drops.I am not sure if it can be used specifically as a trickle charger.

Yes you can but not advised. It will go down to a trickle charge when batteries are fully charged. ok

Well yea, use a battery charger , or a deep cycle charger with a max of 35 amp .Most deep cycle batteries use a slow charge rate anyway which is a lower amp charger.Just keep the amp below 30 to 35 amp @ 12 volt. This is not a 24 or more system charger.

It should work it's just like a car battery charger as long as the voltages right, its just a matter whether it's a trickle charge or a quick charge.

I would think so, for as long as you have sunlight or daylight, you are charging with a couple of watts. You should measure the amp draw of your system though. My particilar vehicle has constant amp draw of 2 to 3 amps and with this solar charger, can extend the life of a full charged battery to about 3 weeks as it only charges during sunlight hours. If I were to disconnect the battery, thus removing the amp draw, it would stay fully charged with this solar charger.

I use mine to keep a 12v deep cycle marine battery trickle charged for use on my automatic driveway gate actuator. Been running for almost 2yrs now I think. As far as a single power source to run something I don't think the constant current is there , it is meant as a device to maintain a 12v battery source from my research. Is that how you plan on using it, as a trickle charger?How much draw is that pump requiring? Good luck

Any 12 volt system can use the trickle charger. It takes 12 to 18 hours to fully charge. The charger can be left on attached to the terminals to keep the battery fully charged. This assumes the battery is not bad.

Absolutely, my batteries are the size of electric wheelchair batteries which are made to run all day without a charge. I charge 4 at once. I use a smaller charger (same Make) to charge my car battery. I would recommend this one because you can select a trickle charge first. Too much charging will ruin your battery. even 6 amps is not excessive.

I only use it for trickle charging. It does keep up with radio memory , but that's a very low voltage pull.

I use a Battery Minder Plus trickle charger. I use my battery with an inverter as a backup power supply.

Yes you can. As stated in my other responses, I used mine for all situations, from cell charger to running power strips to power my house. A separate battery charger is ideal, bc then the charger is mobile, not stuck with the vehicle. I would recommend the Die Hard Branded one from a local auto parts store, roughly $50, it will do AGM(deep cycle batteries), trickle charge and conventional batteries.

I would think not, this is just a slow trickle charger. You are looking for a 12v continuous power supply.

You can use the charger for an automotive battery, if all the battery connections and battery top is very clean. Recommend that the battery be disconnected from vehicle, so that the microprocessor is not reading the vehicle keep alive circuits! I have a negative ground battery disconnect switch to isolate battery from vehicle. Also, charger requires wall current type power source to function properly:)

What a great idea! You sure can hook this panel up to a car or marine battery for trickle charging. For an emergency charge you could get away with not using a controller. Just be sure to unhook the panel before the battery gets to 14.5 volts which will take a very long time with a 13.5 watt panel. This panel would be better served for maintaining a battery charge and you would need a controller for that. I did a quick experiment to verify and posted some pictures in the 'Product Images from Customers' section. All the items I used can be found on Amazon: Sunforce 7amp Charge Controller (I wasn't too impressed with this controller, for regular use the Sunforce 60031 10amp Digital Charge Controller is a nicer model): http://www.amazon.com/Sunforce-7-Amp-Charge-Controller/dp/B0006JO0XI/ref=sr_1_1?ie=UTF8&qid=1387406266&sr=8-1&keywords=sunforce+7amp+controller http://www.amazon.com/Sunforce-60031-Digital-Charge-Controller/dp/B001DZONCW/ref=sr_1_fkmr0_2?s=automotive&ie=UTF8&qid=1387413721&sr=1-2-fkmr0&keywords=Sunforce+10amp+ditital+controller Gino 2.1x5.5mm Male Jack DC Power Adapter: http://www.amazon.com/gp/product/B0058RLD9C/ref=oh_details_o03_s01_i00?ie=UTF8&psc=1 2.1mm DC Power Cord Coupler Female to Female: http://www.amazon.com/gp/product/B002IULV8U/ref=oh_details_o09_s00_i01?ie=UTF8&psc=1

This is from the charge cradles product description "if you leave a worn-down battery in for four to 10 hours, the charger conditions the battery with a tune-up mode, and at completion, it automatically converts to trickle charge, so you'll never damage a battery by leaving it in the charger too long."My guess is you can. I would consider it if I used it frequently

I use a 'battery tender' trickle charger designed for a lead acid 12v battery.

I would not. You could easily overcharge the battery where as a regular charger has a regulator on it. This is to be used to charge another vehicle/motorcycle for a short time; until the other vehicle can be started.
