How long should it take for these batteries to charge with the included charger? and should the light turn green when done?

Between two and four hours. We get about two run hours per battery and yes the light turns green. If the batteries have been used and not recharged immediately, I have seen six hours to charge.

I have a problem, that might be related and I wanted to ask people as well. When I put the battery in the charger (I have two), most of the time, even though the battery is empty, the charger shows green light and does not charge. I have to put the battery in slightly elevated angle and push on it and then it will start charging. So maybe your batteries were not charged at first place. Also happens to me, that the batteries discharge if not in use for 2-3 days, so before use I always recharge.

Can't say I have closely watched the time to recharge. Generally plug in battery and leave it while I do other things. When charging, once you get the solid green light, you should be done. When battery affixed to the light, you should see three green lights. As charge depletes, lights progressively diminish. Once down to a single light, your battery might stop quite abruptly from my experience.

you should charge them til the light is solid green and charge them frequently.

The light will turn green when you put the battery into it, unplugged, but when you plug it in, the light turns amber. Then, when fully charged, it turns green again. I suspect it is something with current draw, zero current means green, positive current means batteries are still charging so amber. Very strange, but it works fine otherwise. Charge Times: My batteries are 4000mAh @ 3.7V. The charger is 650mAh at 4.2V. If you do the math, for two fully discharged batteries it takes 10.8 hours. Unfortunately, I charged them 'overnight' so I don't know exactly, but the 2 hours from John sounds lowball, unless he is just topping off their charge before using again.

It took approximately seven hours to charge two Nitecore 18650 batteries. I charge the batteries on a 30 day schedule and it takes anywhere from 45 minutes to an hour to bring both batteries up the full charge

There is a light on the charger that changes color when the battery is fully charged. Usually, if the battery was totally discharged it will take one to two hours to fully charge.

Plug in the charger, plug the battery into the charger. When the light is solid green it's charged. It does take quite a while to charge.

2 - 3 hours should do it, the led light next to the charging port will change to green when fully charged.

My charger's green lights show if the batteries are fully charged, or if I don't have any batteries installed in the charger. The red lights come on when the batteries are actually receiving a charge. Make sure you have fully removed the protective plactic that covers the new batteries when they are shipped, or your charger will think no batteries are installed, and the lights will stay Green.

I'm not sure, sorry. I generally just plug the charger with a battery into my power strip and when I notice it has turned green unplug it. I've never timed it, but it doesn't seem to take too long. Also, it's hard to say because I have three batteries and after a photoshoot always just swap out the battery for a fresh one and charge the one I've just used, which always has more power still left in it. Sometimes it has 40% left, sometimes more or less, etc., so the time to recharge varies. I seldom run the batteries all the way down, etc. I'll say this... I've been VERY pleased with this charger.

Hi! I have an older model on which the lights never turn green. For my charger it usually takes 12 hours (overnight) to charge up the battery pack. Once fully charged,I can mow for an hour or so. This probably doesn't help too much -- I guess you could test the battery with a voltmeter if you have one to see if it's actually charging. Good luck -- hope it works out...

You need to hold the button for a few secs, you should see a green light on it while it's charging. Hold until you see.the green light. It should be fully charged well before 7 hours.

I'm new as well but have not experienced this. Mine has recharges within 2-3 hours and light turns green. It may be the unit?
