I followed the instructions that were in the package. I believe it was about 4 hours.

On a new sonicare, I have left mine in the charger 24 hours - over a weekend. In regular use, it goes on the charger overnight maybe once or twice a week. Charges should last 3 to 7 days or more, making it great to take on short business trips.

My unit came charged out of the box, worked for a week and didnt even run out before I charged it overnight anyways. Aside from initial charge, which i didnt pay attention to how long it took, I have charged it from dead at night to full 7 hrs later when I woke up so definitely doesnt take 24 hrs to charge

It already had some power to it when it arrived in the mail. I'd say for a full charge it should take between 30-45 minutes, an hour tops

I am sorry, I did not keep track of it, I left it over night charging and I went to bed, next day it was fully charged , my best guess it takes at least 4 to 5 hours.

I charged it overnight. Don't know how long it takes for it to start working.

Charge takes quite a long time before it turns on....this unit is as slow as molasses in January. Good luck

The unit seemed to be fully charged when it arrived. I plugged in the A/C charger and the indicator light turned green after about 30 min. Since then I just plug it in after using and the charge stays on full.

You don't....just replace the old battery with the fresh one...it will take anywhere from 24 to 48 hours. It may seem like it is a dud, but give time and hopefully, it recharges as expected (30-days to return if you suspect it to be a real dud). My replacement took about 30 some hours to be fully charged. In the mean time, I kept getting some odd codes from on my Ademco panel. Once sufficiently charged, the codes went away. Oh, yeah, after sufficiently charged, it gave me a code that my battery in the motion sensor also needed to be replaced. My old battery and the motion sensor battery lasted more than six years.

I think it takes about an hour to charge. The red light goes off when the unit is fully charged.

It seems to only take a few hours. I plug it in overnight and it's charged in the morning.

Your system should be charging it automatically. If you just now installed the battery, wait 24 hours and it should be fine. You may need to reset low battery warning. See your manual for instructions. If it has been installed since February and now is showing low battery , verify the main power source is turned on.

The first time, I was surprise when it finally finished. It really takes 24h! My old one doesn't have the charge progress indicator so I assume that I never charged it entirely!

Hi. I started charging mine as soon as I unboxed it. It had some charge to it but not 100%. So far mine is ok but I hope both of us didn't get a refurbished product. Maybe someone else will reply too.

I've never really timed it, but it seems to take a couple of hours to charge from fully discharged

I usually get a full charge on an empty battery in 4-6 hours. I have two so Irotate them.

It didn't take that long to charge my new battery. I would think a few hours would be good. Maybe you got a new battery that was bad?? Hope this helps...

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

I recently replaced the charger. The new charger is smaller and seems to take longer. I've not timed it, but I would say a minimum of 6 hours for a total charge.
