How long does it take to fully charge the original battery?

5 to 6 hours which is not bad considering, another back up battery its very helpful for a maximum user. I love it . and plus if you plan to go that route for a spare battery you van also have that chargin, while you connect your USB charger to just charge it from your pone as well come with a built in USB charging port.

Full charge in about an hour or at the most, 90 minutes. Charge lasts about 3 or 4 days.

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.

I think the initial charge is longer. I believe it should be 16-24 hours. When it runs down we just plug it in at night and it's ready to go in the morning. The charger will stop when it is full, and not overload it.

If you use the battery that comes with it, about 4-5 hours for a full charge.

probably a couple of hours if substantially discharged. The batteries I'm charging are not totally discharged - I just top them off every couple of weeks to keep them fully charged and it takes 15 - 30 min.

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

I haven't actually timed it but I guess it takes between 2 to 3 hours. It depends on if you are using it while charging.

A brand new battery can take up to 3 hours to fully charge. After the battery has been charged and depleted to under 5% about ten times, the charge that is held takes about 2 - 2.5 hours to fully charge.

If the battery is 1/4 full, and if you charge it at rate of 2.2 amps, it will take roughly 40 to 45 minutes.

I'd say it fully charges within 30 minutes. I haven't timed it though. When I use it it is only on for about 10 minutes and I had to recharge after about 4-5 days. The button to turn it on and off can be very difficult. Sometimes it is easy and comes right on and other times I have to keep trying.

In the packaging it says that it takes a normal amount to get to full, but to fill the extended battery all the way up you should let it charge 12-15 hours.

I'm not sure how long it takes to fully charge; I've left it charging for up to two days and the charging light never shut off. My guess for how long actually it takes to charge is like half a day or something, but that's pure speculation. And to answer the other question: Yes, as long as you're reasonably careful.

I'm not sure about the amp draw, but I can tell you a fully discharged battery takes about 2-1/2 to 3 hours to fully recharge.

It takes about 4 hours to fully charge a new battery, a little over 3 for a discharged (20% remaining) one. It might also depend on electrical current, as it takes a bit longer in Japan than in the USA.

Less then an hour. However, I never stood there to check for every 5 minutes to know exactly, but when I am checking back in an hour the charge is completed. I am actually very pleased with this. I got a second battery also that I am charging when the one in the camera is toward its end...

I've never timed it, but it seems to be only a couple of hours to go from dead to full charge. Keep in mind this device can be used while charging which will likely slow the charge down.
