Does this drain the batteries when left connected to batteries but not plugged in to power feed?

I have never noticed an issue with it draining the batterys. I usually plug it in after each use.

No it will not drain its made to be left hooked up to your batterys, just plug in when you want to charge them

I have two of the mentioned chargers. I can't answer your question since I keep my chargers plugged in to 110V when boat is not being used. I have owned for a couple of years and am very satisfied with product? These are solid state chargers and should not drain batteries unless there is a problem with chargers or possibly wiring connections.

I don't think there's any battery drain, but I can't say for sure because mine is only unplugged when I'm using the boat.

No, you have to plug it in the charge it, but then you unplug it when you use it.

No, it drains into a reservoir, and a light comes on when it's full so that you know to empty it. It turns itself off when the reservoir fills up so that it doesn't overflow.

Mine is connected all of the time to the two 12V batteries that are connected in series. It keeps the batteries desulfated and has even restored a battery that I had given up on..no worries in leaving it connected all of the time!

yes it does. We bought for our toy hauler trailer. Was concerned it would drain the batteries quickly, but it works great. We watch a couple hours of dvd movies and hardly uses up any battery. The tv sound quality is not very good though, we run the sound through our trailer fm radio

I leave mine plugged in all winter and it's fine. I don't think it's a drain on the battery to leave it plugged in.

No,it only has the power outlet connected to the wall and the battery section.

With no load connect, it doesn't prevent the battery from over-discharge from a load. The solar panel can leach power back from the battery during the night though, and that is the discharge referred to that the controller prevents.

I did not engineer this product but usually all modern recharging systems will automatically shut down when the battery is fully charged. Should you unplug the power from the product, and not use the appliance for some time, the battery will slowly bleed off power. I personally leave them plugged in and periodically let them discharge in order to cycle the battery.

It does not have a power switch. I want to say it does draw power when there are no devices connected, but not sure.

Yes. It absolutely does. I have reconditioned /de-sulfated MANY battery packs with this unit over the last several years. It works perfectly and without any babysitting.

I don't believe it does, but am not positive. I always unplug mine when done. Sorry I couldn't be more help.

No this power supply only allows you to use the camera while connected to AC power therefore not using the battery power. You must still charge your batteries with your battery charger. Hope this helps.

No, you plug it in - Regular 110/120VNo place for batteries - supposed to draw minimal power (equivalent to 30W light bulb??). Unit works great!

Hi, it does shut down so it doesn't draw off battery power. I made mine I to a portable meter for installs and that saves my portable battires.

Yes, with this particular model. As long as a quick-connect does not have an internal shutoff it will drain.

It Doesnt. You will need to unplug it or else your battery will drain just like mine.
