Charging Speed? Can anybody tell me how long this unit takes to charge say 4 AA cells? Some can take half a day, others just an hour or so.

The charging current is about 450mA per channel. So if you are charging four 2500mAh AA cells (one per channel) it will take roughly 6 hours. But if you want to charge eight AA cells (two per channel), the charging time will be doubled.If the cells are not fully depleted, then the charging time will be shorter.

Ah! So you are saying that if charging 1,2, 3 or 4 batteries, it is best to place one in each channel - NO in pairs. Thank you for the clarification.

Good question. I had too look too. I think I'm getting KODAK Ni-MH 1-Hour Battery Charger instead.From Rayovac's sitePerfect for high battery usage households. * Charges all battery sizes: AA, AAA, D, C, and 9V * Charges: Rechargeable alkaline, NiMH, and NiCd o 8 AA in 14 hrs o 8AAA in 4 hrs o 4 C/D in 7 hrs o 1 9V in 12 hrs * Automatic shutoff * LED lights indicate when batteries are ready * Trickle charge keeps batteries at full charge * Won't overcharge Good question.

Basic. It takes 12 hours to charge. It's annoying. A simple one day work is a day and a half to 2 days.

The unit uses 4 AA cells and I have been using rechargeable since I purchased it. I hope this info is helpful.

Sometimes it takes 12 hours, I bought 2 battery packs, They last me about a week of riding for about 40 minutes every morning before I have to change. I leave them plugged in to the light so there is always a bit of current draw even with the light off. I have ridden for > 3 hours on a charge and still used it the next day. I really like this unit even if it does take 12 hours to charge.

That is very normal. I have a different unit that puts out 1.25 Amps and it took 3 days for a partially charged battery. This one only puts out 800 milliamps (.8 Amps) so it could take many days for a full charge from discharged condition. Others are correct that this is designed to "maintain" a charge as opposed to actually charge a discharged battery, but if you are patient, it will charge too.

I've never timed it, but it seems to be only a couple of hours to go from dead to full charge. Keep in mind this device can be used while charging which will likely slow the charge down.

It would depend on the charger and how discharged batteries are. I used Sanyo Eneloop charger that charges in pairs to charge 4 of these AA batteries. I plugged it in at ~10pm and by 8am (possibly earlier) the batteries were charged. Other chargers may be faster or slower.

Mine actually takes about 6-8 hours from full discharge. They make other chargers that are faster but this one is budget and very slow. it charges just fine but very slow.

It depends on your charger. I did not pay close attention but I used a 1 amp charger and it took about 2 hours or so.

The charging current of EBL 808A is very low at ~200mA or less. That means to recharge a pair of 2300mAh AA cells will take about 12 hours (2300mAh/200mA = 11.5 hours)

I don't really have to charge mine too often... I'd say between 150-200 tests between charges (I'm not exactly keeping count haha!). I probably charge it less than once a month. Similarly, I haven't really kept track of how long it takes to charge, as I usually just plug it in and leave it overnight, but I can't imagine it takes longer than a couple hours to fully charge? Maybe someone can provide some more exact answers, but hopefully this helps a bit. By the way, this thing is awesome. Highly recommended.

I'm not sure how long actually it takes to charge but it does take quite a while or so it seems.try a little bit longer. I hope it does charge for you.

I have a couple of these installed, and even though it says 2.1A, my iPhone 6 plus charges at about the same rate as the little 1A charger that comes with the iPhone. In other words it takes about 6 hours to go from 20% to 100%.On the other hand, I have a true 2.1A iPad charger (the big one), and it charges the iPhone in less than 3 hours (20% to 100%). So I am not sure it can truly charge at 2.1A.

Another factor to battery charge duration is the normal cell signal the phone has during the day. At a couple of sites I work at, the battery barely goes 8 hours but at my office, it will still be at 50 % at the end of the day. Also as mentioned - what are you running. I found that I only turn on items as needed (WiFi / GPS).

It takes the 2.4 Ah battery about 10 minutes to fully charge...sometimes quicker...So far these are great intelligent batteries...

I haven't actually timed it but I guess it takes between 2 to 3 hours. It depends on if you are using it while charging.

It depends on the device. My iPhone 4s took about a half hour to charge up. It was down to 50 percent. It charges at the equivalent rate of an a/c charger.
