How many hours/minutes does it take for it to charge the first time? I've had it plugged overnight and the little green light is still blinking..

First charge took longer than one night. I left it charging next day when I went to work, and it was fully charged when I came home. I can't tell you how many hours it took to fully charge the first time, but what you are experiencing is consistent with my experience. It is a great brush, I prefer it to my old Sonicare Essence.

My first charge took longer then one night but not sure how long after that.

Hi, I think about 6 hours like the other answers I put it on overnight. I tried to do a test today it was not charged in 5 hours but fully in 8! using an iPhone charger. The easiest way is just to leave it on overnight.

Initial charge was overnight. I left it on to completey discharge it and it took about 8 hrs or so.

I normally charge it overnight, but if I had to guess, it's about 3-5 hours. However, the length of it being able to charge other things far surpasses three hours.

When the green flashing light is solid it is fully charged. It takes roughly 15-20 min for a full charge from 0 - 100, at least from my experience.

It takes about 12- 16 hours to charge. You know it's charged when the red light turns green.

Hi- the charger light goes green when the battery is fully charged. I think I used to charge it overnight (10-12 hrs) and it was good to go. Depends on how fully depleted the battery is.

I don't know exactly how long to charge, I usually plug it in at night and let it charge overnight. However, I would definitely buy a back-up to have ready.

Several hours. I charge it overnight after every hour or two of use, and it's always done by morning, but if it was almost fully discharged to start with (button blinking), it never finishes before I go to bed. You can apparently get a second battery if you want one always at the ready. I recall the instructions say you can charge it as often as you like but should let it fully recharge once you do.

I normally charge it overnight so I'm not sure exactly how many hours it takes to give it a full charge. I'd guess about 4 hours, but that's just a guess.

I'm not really sure how long it takes. I just plugged it in and let it charge over night and it was fine.

Instructions state that first charge and charges thereafter should be 8 -16 hours. I've only charged mine overnight and the light was still red. The overnight charge lasts a really long time.

I plugged mine in for the recommended 8 hours, but the light remained red. As the directions were firm not to leave it plugged in longer, I unplugged it. Did anyone else's light change from red to green when charging it? It works great so far!

It blinks red when charging, and stays red when charged. Haven't run it for long periods, but instructions indicates that it will go 13 hours.

I used an external charger and left it charging overnight so I'm not certain how long it actually took. I was surprised that it came to me fully discharged but after that initial charge it's been working normally.

Well I honestly charge mines all night long and the next day its ready to be used ....but I think the longer you charged it it will stay charged regardless of if the light is on , one time I left it on the charger for days and it stayed charged for a long time

About an hour or so. When it is done, the light goes from red to green but not sure if it continues charging. I have left it overnight charging and it works fine. It's a really good deal compared to purchasing a manufacturers battery. Does the same thing and last as long. Would recommend to anyone.
