I've been charging them for a few hours, they only work when plugged in. They don't work and the LED doesn't light up when the charger is unplugged.

I found they are very comfortable but they don't work. I went through 2 pairs before I gave up. Junk!!!!

I bought the same ones.... They never worked right and the did not stay charged. One of my worst buys (trying to save money. I have a Sharp 3D tv

I do not even try to use them until I charge them fully. I can't see how they could come fully charged.You never know how long they were on the shelf.

I left mine on charge for several days. The light never turned green. The light on the charger went out, and now nothing works. Evidently, at these prices they do not include technology to stop the charger from over charging the battery. I will be attempting to return mine forthwith.

HI - I am not an expert.....not even a novice....but we aslso bought these and when they are charging from any active USB port (i.e. - is your computer or TV turned on?) --it should blink red as it is charging and then green when fully charged......If not ...it is defective. Good luck

Seems like you may have a problem, the lights on my charger have lit up every time I plug it in. There is a possibility the wall piece itself is bad though. Maybe try another USB charger an see if it works. Or put dead batteries in it leave it for roughly an hour an try them again to see if they have taken a charge.

In my experience, if you put them away fully charged, I came back over a month later and they still had a full charge. I always leave the charging battery in the charger for a few extra hours after the charged LED turns green. Seems to work well for me...

I've read that these sometimes have a break-in period and that the charging indication corrects itself after a few days of use. I'd try charging it up and using it and recharging it a few times to see if that helps. Only "problem" is that the charge lasts a long long time! Good luck.

That shouldn't happen. Just the charging light should come on. The greatest feature of these lights is that they are guaranteed for life. Contact them and send it back.

About 2 months ago I purchased 18 of these units. When charging them all, I initially found that only 4 of the 18 green lights on the chargers came on and the rest remained off. However, I verified that although the green light was not on, the battery was still being charged as expected (the charger was working fine, but the Green LED just wasn't working). As time went on more green lights would come on, somewhat sporadically it seemed - but all the chargers were still charging. It's certainly inconvenient. As a result, I measure the voltage on each battery after charging to verify that it reached capacity. About 2 months ago I purchased 18 of these units.

Getting the same issue on mine. Red light never goes off while charging (overnight), and then won't ever turn on using the power button. I've used this model of a friend's, so I know how they work. But these are simply broken, as near as I can tell.

I don't use the charger supplied with the light - it seems to be ineffective time wise. It also seems to have a hard time making/keeping electrical contact, which could actually be your problem. I use an external charger and also have several other rechargeable batteries charged up to use if needed. I know, it's a pain in the butt, but that is the reality. Other than that, they are a good headlight.

If the LED doesn't turn on while you are charging it, then the unit itself might be defective. If it does, then try holding the power button for 60 seconds. If, again it doesn't turn on, then it is also a broken unit.

Well I used them in my solar lights, and they work fine, so I wouldn't be able to really answer charge time. I plugged them early in the am, and that night the lights were working fine.

Same here. They just stopped working for me a week ago. Green light is on showing a full charge, but that's it.

There is no indication that they are charged, just that they are charging. They will fully charge in 3 - 4 hours. I have two of these dual chargers and two single chargers and i built a timer box to supply power the the chargers. I usually set the timer for 4 - 6 hours.

Tony,I have not had this issue, after the 23 hours of charging, when you check the battery indicator lights, are all 3 lit. if they are, there is no issue. the battery is at full power. Otherwise run the battery until fully depleted then recharge. usually they take a few times to come up to full power. Hope this helps!

I'm not sure... Mine do charge, but the charge barely lasts more than a day so i don't know if they aren't charging well, or just have horrible battery life. I've had mine a couple (2-4) of months
