Does it harm my car battery if I leave it plugged in when the car is not running? Does it still charge when the car is not running?

It does not harm the car battery but it harm the side contact spring of the charger. This is the most weakness part of the charger because the contact spring need to be welded to the electrical board & creep over time if you let it plugged. If the car key is turned on, it can charge when car is not running. Hope this answer your question.

You should never leave electronic devices (charging or otherwise) plugged into receptacles that power them when engine isn't running.. You wouldn't leave yourheadlights on with the engine off would you. They allare drawing power, energy from the car battery when the alternator isn't charging it up.

No leave the battery in the device. The circuitry detects if the device is receiving power and then charges the battery and runs the device at the same time. When the battery completes charging the unit continues to run on AC till you unplug from the wall socket. It is a nice feature that you can run it and charge the battery at the same time.

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.

I'm not sure I understand the question but I can tell u I have no problem charging this light in my car. I am not able to charge anything in my civic if the car is not running. The cigarette lighter has no power if the car is off. Perhaps your car is the same way and that's what the issue is.

No, don't leave it plugged in. It will drain the battery. The green light is cool but it drains the battery slowly but surely.

You can leave it plugged in if you wish. I usually unplug it after fully charged and let it sit. It keeps the charge for many weeks.

Do not use the light if it is plugged into the wall or your car. It would ruin your battery. It should only be used after it is charged.

Oh, whoops. I used mine while the engine was running with no problems. My 12-volt ports aren't powered unless my car is at least in accessory mode.If you're really afraid of your battery dying, you're probably ok using it with your car on. Just wait until your car is started before plugging it in (to prevent a surge) and make sure your parking brake is engaged.

I leave mine on a charger at all times and it doesn't appear to damage or effect performance. perhaps there is some battery expert out there who can offer a more educated response.

I bought this for my wife to use in the classroom so it is always plugged in to an outlet. We've never used it in the car so I don't yet know what effect it might have on a battery. Sorry.

Actually my husband uses it in his car, and he does tend to leave it plugged in. I myself don't recommend it.

It depends on your car some cars have slow constant drains in them from security systems and lighting and advanced electronics and these would trick the Sansour into giving incorrect readings on your batteries voltage so most of the time the battery is suggested to be disconnected but if it's just for a little top off charge you can get away with it

I run mine on the car battery while I'm driving AND when I park for the night. I start the car for a while before bed time just to ensure there's enough power to keep it cold through the night. I never have drained the battery though!

Yes, it needs to be plugged in to your car's battery directly, or your car's cigarette lighter, while the car is running. It comes with cables for both. it does not store power, as it does not have its own battery.

Yes, this is intended to remain connected to a battery 24/7 (whether in a car or out of a car) and it begins charging the battery when solar power is available and the battery voltage is 13V or less, then once the battery voltage is raised to 14V (showing it is charged) it will stop the charging. If you will be connecting a solar panel thru a lighter plug in a car (which seems to be the easiest place), I hope the lighter remains "on" without the keys in the ignition (otherwise your "charge" power will not be getting thru to the battery making putting all of this together pointless). If you were to start a car with the panels connected up, the panels may send their rated power to help start the car (during good daylight), but they won't put out any "extra" power (they are not a battery that "store up" power or such, they just give you what they can). Once the car is started, the car alternator should instantly recharge the batteries and the green light on this should instantly come on (showing that solar power is blocked).

You must plug it into the cigarette lighter of your car to work and the car must have a good working fully charged battery in it. It will work with the car turned off as long as your car battery is fully charged. BUT it will in fact drain your car battery if you use it while the car is turned off for a long time. I have used it for up to 30 minutes to charge a cell phone, and I've used it for about 20 minutes to run my lap top, both times with the car turned off and I had a fairly new car battery but I would not go any longer than that and I would not use it with the car turned off if your car battery is not new or is not a high quality brand.
