how long do they take to recharge when completely depleated, are they comfortable to where

Approx. 2 hours , these are ok to ware , but it is not warm enough for me , I'm riding the bike in 30-35 degrees ,

They fit well into my boots well and are comfortable a couple hours should have them recharged

Oh, and it does not take long for these to go completely go dead ! One of it became discharged in 1.5 hour ,

They take approx. 3-4 hrs to re-charge from a dead state. They are very comfortable.

Another reason not to use rechargeables is that they can drain while idle more quickly than alkaline batteries. I wouldn't use them if you will be gone more than a couple of days.

after drained, you should charge again, and if you drain to a half capacity, you don't need to wait for full draine (discharge) to recharge again, it doesn't have memory effect, so always u can recharge the batteries without worries about how much drained has been.

I'm not sure about the amp draw, but I can tell you a fully discharged battery takes about 2-1/2 to 3 hours to fully recharge.

not easily -- they recharge themselves in normal operation. We havent done any thing to stress-test how long the batteries last before needing recharge.

Short answer - yes. However, if you try to use them after they have reached their "protected" level of discharge, you can get them to discharge so low they will not recharge.

Tricky question to answer but short answer is No, these are high quality batteries that basically do everything they say. And there is no memory effect and no need to fully discharge in order to achieve optimal capacity. I tested these batteries new and they got over their rated capacity. That being said, all batteries degrade over time and use, so fully discharging and then charging will help them come closer to their full capacity. However, if a low quality charger is used such as a "fast charger", then the batteries have been baked by the cheap charger and their capacity has been permanently reduced, no matter if you fully discharge and recharge or not. You will get long lasting results from using a charger like the LaCross BC-1000 or Powerx MH-C9000. Both of these chargers are excellent and work quite well. I've seen other cheap batteries only deliver 50% or less of their capacity, but they were also fried by a cheap charger. It sounds like your batteries have been somewhat fried by a fast charger. You might be able to restore them somewhat by performing the full discharge and recharge that you mentioned, but I've only seen capacity increases of about 15% with this procedure, so it's not a perfect cure. One other thing to consider, if you are using these batteries in a heavy drainage application that is pulling a lot of current and using the battery up quickly, then all batteries will under perform in this situation and will not deliver their full rated capacity. If a 2400 mAh battery was drained fast at 2400 ma, it would not last for 1 hour. You might get 40 minutes or less. But if you drained 100 ma slowly from it, it would easily last for about 24 hours.

It depends on how much battery life is left. For me, it usually took about 1 to 2 hours to recharge full. I hope this helps.

I havent timed it myself but I would say from complete dead to recharged , 1 1/2 to 2 hours

My 2 cellphones use this kind of batteries. From my experience it takes about 3 to 4 hours to fully charge them. They seem to work fine for me.

I would say that I easily get about 7 hours before it totally conks out. Recharging these also seems to happen very fast, within say no more than 30 minutes.

Leon, I've had mine go for 3 full days with intermittent use maybe 3 to 4 hours a day, before I've become afraid they are going to be dead and charged them.

A fully discharged battery will typically take between 20-30 min to recharge fully in my experience. Longer if the battery is hot when it is placed on the charger.

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.

These batteries do not have a "memory" so they can be charged at any time. They do not need to be completely discharged before recharging.

I haven't really timed it, but it seems to be taking about a day to recharge a pair of AA's. Longer than I expected, but I just replace worn out batteries with ones that are already charged up and then put the dead ones in the charger. Once they are fully charged I put them in a storage box until the next time another pair runs out of juice. Overall I'm very happy with the charger.

It took me several days to recharge after draining the power the first time. It is not unusual for these types of power packs to take one to three or four days to fully charge. You have to plan ahead.
