How long does a single battery charge last? (assuming the light was left on highest setting.)

Don't know how long it lasts if left on for a long time. We use it all the time and it never shows signs of dimming. We let it charge about every six - eight weeks.

Depends on the brightness set when on battery and how many applications are running. The brighter and more processes there are, the quicker the battery drains. If it's just for light use and not blasted on full brightness it should last about 3-4 hrs, at least that's on my laptop.

I use my lamp on and off for a week or two before changing batteries. If used steadily they would last somewhere from 6 to 10 hours I'm guessing before changing batteries but I'm using rechargeables. They dim steadily when the batteries loose charge. It's the best clamp lamp I've ever had and withstands heavy use. Very sturdy.

one night we were doing a bbq outside and it was giving at least an hour of light: the light did not have full charge. the light is pretty bright.with full light it can give you a more than 1 hour i believe. but I don't know about 4 to 6. I don't think it is designed for this long or for constant light, This light turns off automatically if no movement.

Yes! With average use and backlight on (dimmed), charge lasts about 30 hours.

When the battery charger was working, it took about 3 hours. Shortly after i got the flash light the battery charger stopped working. I would say the light lasted around 8 hours of continuios use on high.

Um..... It should never be on unless charging. You did not charge it when you first got it did you? It comes charged. From then on it only takes a two hour charge. If overcharged and battery ruined the light will stay on.

I believe the instruction say the light should not be operating during the charging cycle (USB cable plugged in). I remove the light from the mounting bracket when I get home and charge it in my house during the evening, that way it is fresh for the next day. I use the light on my commute about 30 minutes a day on the way home at night. I usually charge it up after 3 uses, but I suspect I could go longer.

It varies based on the power of the charger you are using and quality of cord. It's a long time 6+ hours if you are below 2 power lights.

Ray, I asked the same question and never got an answer. The first time charged, I let it go for 8 hours and the red light never went out. If I use it for any length of time, I charge it for at least 8 hours. I have it marked on my calender every 4 months to charge the battery and most all the time, it does not need the charge at all. This is the best lantern I ever owned. This is what worked for me. I hope it helps.

Hard to say exactly because it depends on the intensity of the sun. I charged up mine totally in two full sun days.

I initially charged it overnight, and it lasted for several weeks of ~1 hour long rides. However I don't ride with it always on the highest (brightest) setting - it has three brightness levels, and I usually ride with it on the lowest or middle level, only using the brightest level for short times when I really need the extra lighting.

A few hours. I have yet to read of anyone who has gotten more light. It works long on first use only, then very short battery life.

About an hour or so. When it is done, the light goes from red to green but not sure if it continues charging. I have left it overnight charging and it works fine. It's a really good deal compared to purchasing a manufacturers battery. Does the same thing and last as long. Would recommend to anyone.

2 hours with all 48 LED's is about the max depending on the amount of sunlight it gets between uses, it takes a full day of full sun exposure to fully charge so anything less then that will shorten the duration

Not sure. I just charge it and is lasts forever. Don't pay attention to light. Will try and see

Like the others have said, it does NOT have an indicator to tell you when it needs charging, other than a dimming of the light output. The company does publish a table that tells you how many hours a charge will last, depending on what light setting you use. If you use the lowest light setting, like I have started to do, it lasts 10 hours!
