Sometimes 8 hours so I charge my cell phone battery overnight, I have 2 batteries for my cell phone.

The first charge should be 14 hours to give your battery full capacity charge. Then, one 3 hour charge will last for about 36 hours, or you could charge it every night like smartphones.

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.

Read the instructions first; which constitutes the amount of time needed to keep a charge but it takes around 10 hours at least that's what the instructions on my battery said to do.

I would estimate about 45-60 minutes. The number of charges obviously depends on how you use your phone but I can get up to two full charges.

I hard charge my battery everytime...overnight. I suspect it would take a full 8 hours. I also carry a second battery with me....never want to be caught out with a dying battery 25 miles from home.

Not long at all. I barely get a 20% charge from it. It causes the phone to overheat and that battery case turns on and off when it wants. In my opinion its junk don't buy it. I would suggest buying the opteka 6000 mAh solar charger.

The charging current is 300mA. So to recharge a set of 2000mAh batteries will take about 7 hours (2000mAh/300mA = ~7h). Shorter if the batteries were only partially drained.

Using a 1A charger, it took me about 7 hours to charge from empty. Keep in mind that when the battery is very low or near full capacity, the charging rate is less than 1A due to the design of lithium batteries.

None of these answers look right to me.. From the manual: "It takes at least 24 hours to fully charge the battery". From the quick start guide: "Before you start, charge for 2 hours minimum". Basically: 24 hours for a full charge. If you can't wait to use it, make sure you charge for 2 hours before using it the first time.

Remember to treat it as though u are openining a new phone u must charge the battery first for six or eight hrs.

Depending on the battery condition the charger may take more than 7 hours. The last amount is at low current to fully charge.

It depends on your charging method. A few hours via AC power with a depleted battery. Crank for two minutes, rest for a minute, and repeat.

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 would say about 3-4 hours, then the batteries have to be replaced. I usually use mine about an hour at a time. The batteries are expensive, but it really does come in handy if you can't plug your phone into an outlet.

I am able to charge a Samsung Galaxy S3 and iPhone 5. You need to continuously crank around 80-120 per minute, so between 1 to 2 times a second. It took an average of a minute and a half for one percent battery charge, which isn't bad. I believe it would charge faster if I turned the phone off while charging. In an emergency cranking for 10-15 minutes will get you enough battery to make that emergency call/text message.

I have those same batteries and it takes between 2 and 4 hours to charge them depending on the level they are when you put them in.
