How long does it take to charge a battery from 0 to 100%? Mine took 7, 8 hours. Is mine defected?

I have not timed it but that sounds close. I just swap mine out of the phone because it takes less time to charge than it does to run the battery down. I also have 3 batteries total so I never run into a problem.

No, it's not defective at all. These are large capacity batteries, and the wall charger does not charge the batteries with a large current, so charge times take much longer than if you were charge the battery inside the phone with the included charger, which has technology in it to charge quickly. While it does take awhile to charge, since there are two batteries, it usually isn't an issue for many as one battery is charging while the other is being used. In addition, the fact that the Anker wall charger (as well as most other separate battery wall chargers) don't use a large current means that when charging the batteries with it that typically the batteries will have more recharge cycles and will hold a larger capacity for longer as compared to charging it faster (i.e. in the phone).

That's probably about right although I'll check next time. I think mine might have been a hair under that. Maybe 6ish.

Thats a good charge time using their charger. If you use your Samsung charger and the phone it will charge more quickly

Both of my batteries arrived about 50% charged. Each took about 4-5 hours to fully charge (red LED goes off and blue is lit). It's just a very low power charger. A slow charge is supposed to be good for the batteries, but it's not good for me when I'm in a hurry. When traveling I'll charge them in the phone with a 2 amp charger.

Not sure you really don't want to let li-on batteries discharge completely. It kills their lifespan. It takes about 4-5 hours to charge from 10-15%

That is around how many hours it takes to charge mine when using their charger. It is done by the time the second battery is drained low from normal use, and then I just swap them out. If you charge one in your s4 cell phone using your OEM charger that the Samsung S4 came with, then it is much quicker.

I've never let mine get completely down to 0%, the lowest I let it get down to is 20%, but so far on an average charge, is usually 6-7 hours. These are larger batteries than most so will take longer to charge.

depends on how discharged your battery is . most of my batteries were charged within 24 hours are less. sounds like you have a battery with a weak cell that will not let the battery come to a full charge '

Mine. only took about 2 hours. I think It depends on how much of a charge it has when you get it.

Well I let it charger like 2 hours .unless that your charger is broke. Try to power it on to see if it work.

Put the battery in the charger. Usually get some type of indicator light that it connected and charging. It seems like the batteries take 5 hours to fully charge.

I didn't charge mine before use. Upon receiving my battery it had about 60% charge. To fully charge the battery takes approximately 2 hrs.

Hi, we charged it over night. I wouldn't do less then 8 hours to get a good full charge the 1st time

I'd give it a few hours plugged in time to charge the battery. If that doesn't work, I suppose it's defective.

Are the 6 charging cycles supposed to be 12 hours? After my first 12-hour charge, the battery lasted for well over a week and I left it on all day and night. I let it go down to 20% then did a regular charge which was only 2 hours or so. The battery dropped to 81% in one day with minimal use. I didn't even leave it on the whole day.

I know this sounds stupid but make sure the battery is inserted properly and that it is in all the way. My charge time has been 10-20 minutes. My original battery charge lasted 6 months.

I initially charged my battery once, for a full day. After that a normal charge takes 3-4 hours.

Are you getting the message at the control panel that the battery is charging? I think my new battery took 2 or 3 days to fully charge. Give it another two days on your battery.

I only takes a couple of hours for mine to charge. Sounds like your charger or battery is faulty.

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.

In my experience it depends on how far it has been discharged. The times I have needed to fully charge it, it usually takes about 2-3 hours.

I got a similar unit recently and when I plugged it in, it too showed 100% charged. However, I unplugged the charger and checked the battery voltage which instantly dropped to under 6V. So that told me that the battery wasn't accepting a charge and the "100%" reading was coming from the charger just while plugged in. So I left it plugged in and after an hour it did start accepting a charge and the reading dropped to 60% or such. So it does take at least 12 hours, after that if it starts displaying 100% it probably is charged.

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