Charging Speed? Can anybody tell me how long this unit takes to charge say 4 AA cells?

Good question. I had too look too. I think I'm getting KODAK Ni-MH 1-Hour Battery Charger instead. From Rayovac's site Perfect 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

Around 4 hours on a 1A charger but it will depend on how powerful the charger is.

It takes 3 AA cells. Sorry, cant say how long they last-- so far it's only been used with the AC power supply.

After timing several charging cycles, it appears to take 4 hours on average.

These are not easy questions to answer definitively since it runs automatically and I have never just run it out of power to see how ling that takes. Having said that, my estimate is about three hours run time. I have my unit run every day and it usually runs for over an hour with no troubles. It returns to the charging unit on its own. I have often run it for an additional 60-90 minutes within a couple of hours of a previous usage with no problems. So it seems to charge quickly.

Running it hard about 30 minutes. Getting used to it and taking it easy is more like 45 to an hour. Just make sure you fully charge battery before using it. I recommend getting a better charger. I got the 2 amp one for 20 bucks and it charges this battery in about 2 hours. Thinking about getting the 4 amp charger for 40. Twice as fast

Hello,It takes about 30-45 minutes to charge. A problem I and a couple of people have had is the charger finishing before the standard battery is fully charged. This light appears to be only good for a short trip about 45 minutes on low. Another problem is the mount. You can look at my review under KRB on how I made a mount.

In general, you can get an approximate time for charging anything from zero by dividing the mAh rating by 1000 and then dividing that by the amp rating of the charger. So in this case, you get 50,000/1000 = 50, which you then divide by the recommended 2A charger, and you get 25 hours. I'd add about 10% to cover efficiency losses, too. (This also means that using a 1A charger would require over two days to complete a charge.) Those who claim it can be charged in two hours are wrong. You'd need a 25A charger to do that, which don't exist for USB. You'd destroy the batteries anyway.

2-3 hours maybe, higher mah longer charge time unless you get one of those 100 dollar chargers lol

The charging current is 400mA when charging 2 cells in series, 800mA when charging 4 cells. That means a pair of 2000mAh batteries will take ~5 hours to charge (2000mAh / 400mA = 5hr). It does not matter if the power source is rated 1A or 2A. You cannot charge any faster.

I have a nexus 5 and it takes about an hour to charge. If I use my external battery it takes maybe 15 minutes to charge to full.

It takes very little time to charge, maybe an hour. I can definitely say not more than 2. I haven't timed it yet. I just know it's pretty quickly. It certainly charges faster than my old rechargeable batteries LOL

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.

Charging current of Sanyo MQN06 is 300mA. To recharge a pair of 2000mAh AA cell would take about 7 hours (2000mAh / 300mA =~7h).

Hi Lawrence, In a wall charger it takes about an hour, mAH is 4900. Just be aware this is a large battery and adds a bit of bulk to my Sony Handycam.

If you're asking how long it takes to charge this battery, approximately 6-8 hours if you use a 2.1 amp charger

I am going to say no David. I can tell you I also bought a Tenergy Advanced Universal Charger TN190-4 Channel AA/AAA/C/D/9V Ni-MH Charger with LCD Display and USB Power Outlet and it takes about 8 hours to charge 4 at the same time. That is a conservative estimate. You may be able to do it in 7, but no less I am sure of that.
