How long will the light burn on a fully charged battery?

I've never timed it, but it lasts much longer than I would have expected. Several hours on high....longer on low. Definitely worth the price in my opinion! And easy to charge in a windowsill during the day.

Used it camping this summer, lasted several hours on high and provided great lighting. I also bought a few to take to Africa when visiting my son in the Peace Corps there. The kids were using them for homework at night and seemed like they lasted a long tome for them. They were pretty excited to have light at night so left them on a long time!

I don't know. I did leave it on all night once by mistake and when I got up in the morning it was very weak but still had a light.

Hello there, I really never used to that extent. so far I used not more than five consecutive hours on low. I mean I didn't push to the limit.

I bought the earlier S10 version. The light output is unregulated - so as the rechargable Ni-MH battery runs down the LED output reduces. For output to appear twice as bright at low light levels one needs four times (squaring) the output - this is why the difference between the 4 & 8 hour settings is not particularly noticeable. At the high setting it might only appear ~40% brighter: 2^0.5.So the "UP TO" runtimes are only suggestions; with initial light output reducing over time. Use it as you see fit. Remember rechargables reduce in capacity over time, & only last a limited number of cycles. I bought the earlier S10 version.

It doesn't take more than about 2 hours from a 0% to a 100% charge. The battery is good for about 3 hours of VERY bright light :)

Depends on how dead the battery is however the instructions say not to leave on charge more than 24 hours. The charger base has a green indicator that lights when fully charged.

I use it at full brightness and the battery last around 4hrs when it is fully charged.

My best calculation says about one hour on a fully charged 160 AH battery. That would reduce the battery to half charge, and you don't want to go lower.

There is no light to designate when fully charged- I usually leave it 3 or 4 hours and it seems to be adequately charged to drive a lot of screws. I actually have 2 of these- even the one 4 or 5 years old still holds enough charge for up to 100 long decking screws and the new one does more. I found the new drill/battery cost the same as the replacement battery alone.

Depends how long you leave it on. If you leave it on all night, probably a couple of weeks. It gets dimmer as the batteries die.

i think that really depends on the quality of the battery you use. i use the amazon brand "AA" batteries and have used the lite with both down and up lights on for about 5 hours consecutive use and they did start to dim slightly. but as i find you don't really need more time than that for an evening on the patio. you need to keep in mind this a temporary lite source for your patio table and is not meant for long burn duration's. with that in mind, it's a good investment for the money. it's also good to have around in case of a power outage!!

I do not think the light was designed to be left on continuously. I have mine set for one minute on when the motion control activates it. I think this setting is adjustable. Even though it is powered by solar batteries, I would think that a couple of hours would be the max on time for a full charge. It was designed as a security light to come on for a short time when triggered. If you need continuous light, a hard-wired device is your best bet.

I would expect a few hours for a full charge. What indicators do you have of battery level? There are indicators on the bottom of many packs. Push the button and see how many lights show. Also, if you are using your computer heavily with screen at full brightness, a lot of the juice will go into running the laptop. There won't be much left to recharge the battery. You might try putting it aside to sleep for an hour and checking back later. Of course, if the battery is bad or the calibration is way off, that is another thing. If you charge a sleeping computer all night and only get 30 minutes of use before it's dead again, that's not good. There are ways to address that but someone else may know off the top of their head.

It depends on which charger you use. A range would be 2-8 hours. I don't wait for the batteries to be fully drained. It doesn't harm these batteries to be recharged if you notice that your flash light is not as bright as it was after a recharge.

When the solar panel has full sunlight, no obstructions, my light will go for at least 5 hours. I say "at least" because I'm not paying attention the entire time. I use it to light the trunk of a tree.

I've used mine for more than three minutes (after having cranked quite a bit and let it sit for two weeks). I can get four or five before I have to crank it again.It will last much longer and still produce light, BUT it will get dimmer and dimmer as the charge dies. That said, it recharges very quickly.

I've never done more than an hour at a time on maximum brightness, but I'd expect to get at least an hour or two from a fully charged battery

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.

Between 6-7 hours full light on low power mode after 7th hour the battery will start to get low and the light will start to dim lower for an hour then it will go out

More than 2 hours actually. I left mine unplugged running at max brightness overnight to see how long the battery will last. I was up for more than 5 hours before falling asleep and it was still running. Light at max wasn't as bright compared to when it was plugged in though. There's most likely a circuit preventing the battery from over discharging as it turns on then off for some time still before I plugged it back in.
