how long does it take for them to charge up at first use

Mine came on as soon as they were put up. I think might have left the solar panel only in the sun the day before and made sure everything was working before having them installed.

To be honest I don't remember. What I do is always charge 24 hrs. with these types of batteries. What I can tell you is that these lights work flawlessly and Im glad I bought them. I haven done anything they charge go on and then off no delays. Great product. And believe me Ive had others and these works best.

probably a couple of hours if substantially discharged. The batteries I'm charging are not totally discharged - I just top them off every couple of weeks to keep them fully charged and it takes 15 - 30 min.

It does not take long. Charge an hour or so before using and leave the second battery charging while you use the first one and then just alternate use of each.

Make sure you wait 15 minutes after using your battery before you charge it. If you charge it right after you use it they won't last long. You have to let them cool down.

I actually plug them in to charge and forget it. But I would guess an hour or two would be sufficient.

30 or so minutes to charge. . With continuous use, it stays charged 4 or 5 hours. Actually I've never had them go dead on me if that means anything

It depends on how low the battery level is. If you are charging it from 0 then it will take about 1.5-2 hours.

It takes about 30 minutes to charge. It will usually stay charges for around four hours.

It depends on how you charge them. In my experience, it takes about 30-60 minutes to charge them using the AC adapter they came with (5V, 2.1A). It takes twice as long to charge them using a standard USB port (5V, 1A) and only 15-30 minutes using a 5V, 3.1A charger. The headphones are rated for 12 hours of wireless listening, 20 hours using them in wired mode. That is about accurate as mine drain after about 11.5 hours of listening, not straight listening but sporadic throughout the week. That's listening at a moderate level though (about mid-volume). Listening at a higher volume will drain the battery faster. It depends on how you charge them.

Hi, it took about 3-4 hours for the first time charging. When I charged the pack, before I used it, all the lights were on except one. I would wait a couple of hours and if the status has not changed, it might be defective.

About 48 hrs. My Mother and daughter kept theirs on so they could keep up with each other. When they tried turning them off to save battery power, that seemed to eat up the battery life even faster. They are not using them at all now. It goes through batteries too fast and I still have not been able to find a charger that fits the adapter plug on the side.

I charged mine for 24 hours before using them. They work great! I have noticed that when they are not plugged in they only stay charged a couple of hours.

I charge mine over night and then use till it starts to slow down then over night again. I have forgotten about them in the charger for about three days, they were hot, and over the years it seems to shorten the life of the battery. so 8 or 10 hours for full charge.

I've had mine for months and only charged it the initial time. I don't recall how long it took. I only use it a couple of times a week but the charge has held.
