Will it still have an internal charge even at night if I want to have the lights on my boat while not draining the battery?

Agree with Todd & Kate. It is what it is, a "solar" panel depending totally on UV rays to generate a charge. The panel will not generate a charge at night nor on dark overcast days.

No, it requires the sun to charge and does not store charge. It won't contribute to draining your battery so you can keep it plugged in.

No... but if you are talking about a battery that had the lights left on overnight and 'dead' it will not charge if it is below (I think 2 volts) some minimum voltage left in the battery. It IS very frustrating because the older 'not so smart' chargers would at least try to charge a dead battery where these smart ones won't work at all. I faked one out once by connecting a small motorcycle battery to my dead car battery and fooled the 'smart charger' to start working and then put the motorcycle battery back. Battery was fine after about 6-8 hours of charging.

no. it is strictly solar charged. not as great as I thought it would be. I would not want to read by this light no matter what anybody says, but it definitely beats sitting in the dark.

I have owned several and they are safe to leave unattended on my houseboat in the winter, but always plugged into a grounded wall socket. They pull too much voltage to plug into a cigarette lighter i would think. could drain your battery very quickly and maybe even short out the heater.

Im not 100 percent sure but ive left my lights on over night by accident and it didn't kill my battery. But every bike is different.

I charge mine every month the battery last quite awhile. I use the light as I'm coming out of work at night..I have purchased several of these for my children.

You are right it drains more then charges, that's why I wouldn't buy one. When the sun is shining bright it charges but when the sun changes angles and the light is less it discharges so if you do not disconnect it approaching evening it will discharge and in the morning it will be low or dead.

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 would think so Alan, but maybe ought to call Battery Tender. I leave my two boats plugged in for months at a time, and when I'm ready...they're ready...at least the batteries are!

I have run my boat battery down several times and within 4 hours it is completely charged. This would of course on the life of your battery.

Mine came with a charge on it, but, I charged it over night just to be safe.

Yes. At least one of the four battery level lights should come on, depending on how much charge is left.

No. Under the lid is a small plastic tab you have to pull out. Once you do that the sun will charge the battery and you will be ready to go. It turns on when it gets dark...but as I said you must pull out that tab. Hope this helps. If not write me back. Good luck and enjoy your lights.

It will take a separate battery. good battery will charge during day and run lights at night every night all summer. 12 volt LED lights will run all night and battery will be ready next day if sunny out.

Yes. Charges in the sunlight for a couple days under direct sunlight. You will see a red sensor light @night when motion is detected.

It will charge the internal battery. If you hook it up when the internal battery is fully charged, it will keep it that way. However, with mine, it failed after the 4 recharge and was totally worthless. I tried to contact the company and they never answered. Amazon couldn't could not, or would not do anything to help me. I would advise that you forget it unless 4 or so charges is worth the price it costs.

As long as a device is not actively pulling electricity through the port, then there should be no strain on your battery. Your lights drain your battery because the device is engaged and actively pulling a charge through its circuits. The only issue I have had with leaving the device on is that even when my car is in the garage, my phone still passes the calls through it. Makes for an awkward first 15 seconds of a conversation....
