How long to "recharge" these? Plugging in for up to 18 hours (per manual) does nothing.

I have 4 of them and the recharge times vary tremendously. I just keep it plugged in until the color returns to deep blue and the moisture droplets disappear from the window. I have found it better to recharge it using an extension cord and laying the unit on its side so the moisture can drain out of the vents as it heats up. I flip it from side to side every 6-8 hours so the moisture drains out more evenly.

I plug two at a time into an outlet strip (these E-500s are way to heavy to plug directly into the wall) for about 24 hrs and the indicator changes back to blue. I live in FL so I'm usually recharging these every two weeks.

You got yours to work? How'd you do that? Haha I can't get mine to soak up anything. I know it's humid too!

When I plug in the ones I have they get fairly hot within an hour or two. That's how I know it's working. The heat is necessary to evaporate the moisture from the silica crystals. I recently recharged a couple that had been neglected and it took three days to evaporate all the water out. I'm happy and very satisfied with the units I have so far.

We have only used them after charging overnight. I assume only, they are not quick charge.

These headphones will charge in about an hour. You must use the supplied Usb charger or one with a similar small plug to ensure electrical contact. Charge light on phones should glow when charging. Hope this helps. Nice headphones

They should be recharged. These batteries may be recharged many times if they are used properly and not left on until they are completely dead.

3 hours max. Mine usually take 2 hours to recharge, but I don't run them all the way down.

Leave them plugged in for an hour or so and recheck them. I believe I had a similar issue with these initially. I'm anxious to hear if this works for you. I've been really pleased with the lights I am using in our house. Helps so much at night.

Recharge these anytime. In fact, best to NOT let these run down entirely, as these (unlike Ni-Cad) have no 'memory.'Mainly don't overcharge. These take about a 2 hour charge, and overcharging in an attempt to bring them up to full capacity cause battery 'stress.' You can get the full, more scientific answers to your questions if you Google. Also, remove from charger after charging.

When I first got mine, I charged it for a least 24 hours. The On/Off switch should function easy to turn the device on/off. I am not sure WHAT is the problem with yours. It very well may be a defected device......?Sorry, Wish you luck...!

One or two hours at most. The worst thing is to run them all the way down, then put on the charger and forget about them. If you will look on Amazon. Under some or the batteries, they give you the do's and don't of how to get the most life out of your batteries.

I believe the box says about 1,000 hours and then you need to toss them in the washing machine to "recharge" them.

Hi Scarlett, the first time you charge them, it takes a bit longer......I am thinking about three hours. Then once they are charged the first time, it only takes a little over an hour most times. Although there is no way to actually check battery life, the battery lasts quite a while. I have never ran it empty in a single use yet, and I just make sure I charge them after each use. They are super comfortable, and the sound is really good. i really love my iFrogz. Hope this helps.

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.

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.

I see many have answered already. I get about 6-8 hours, then when it beeps in my ears I use a longer usb cable to charge them while using them. win.

I've used mine for several hours. I havent timed it but I've been very happy with my purchase. They will also provide a light beep to let you know before they die to plug them in.

No idea... But when they worked, I loved them.... Then they didn't, after about 15 hours of use.

All u do is plug in the usb cord into a power plug!! And the light turns red , then they are charging. If that doesn't do it there is something wrong with them!
