How long should I charge these batteries?Thanks

You can charge until the green light on the charger comes on. A matter of a few hours. Good luck. An overnight charge will also do it with no problem.

It becomes obvious when the battery's need recharging by the lack of brightness from the light. I bought an extra set so I have fully charged battery's in case I need the light for a longer period then one set lasts. I hope this helps..

I only have one set of 1200ma batteries. I now only purchase the 2000ma size. But to answer your question, I believe the charge time depends upon how discharged they are but normally it takes me about 3-4 hours. I just plug them into the wall and go on with my computer work and when I stop for a break they are usually done charging. The 2000 ma ones are ~67% more capacity so get those if is convenient. Not much extra cost either. Hope this helps...

They aren't quick-charge batteries, but the charge will stay a long time, unlike nicads. Charge time varies, but it's around 8 hours if they are mostly depleted. There are blinking lights when you start charging, then go solid when finished. Each battery is charged individually so one could be done and another still blinking and charging.

I have three Batteries and keep them recharged while I use one of them for a work most of the time. I guess a couple of hours to recharge one. I notice I have to charge them more frequently lately. I wonder they are getting less powerful.

Are you using the NP-550 rechargeable? I haven't had any problem with them lasting at least an hour or so. I actually turned them both on and left them on till they died and they both lasted an hour. On the other hand when using 6-AA's (supplied with the kit) they went out in about 20 minutes. They are very cheap batteries.

There is no indication that they are charged, just that they are charging. They will fully charge in 3 - 4 hours. I have two of these dual chargers and two single chargers and i built a timer box to supply power the the chargers. I usually set the timer for 4 - 6 hours.

Depends on the strength of the charging supply. A couple hours. I do them overnight.

These batteries will charge in an hour. Two hours, two batteries... Or close to it

I have used them for 6.5 hours so far today on one charge. The battery is still going.

I haven't had a problem with them charging but I leave them on the base when not in use. I have previously had a set that has done very well for 5-6 years. It was time to buy new batteries and it was easier to just get a new set. I'm also very happy with the distance they work well from the base as I tend to have them with me when I work outside.

Depends on how many batteries and how discharged they are. I use mine for vaping. Fully charged they are 4.1v. I recharge them when they get below 3.6v. I have not timed the recharge but believe it to be less than 1 hour. The fewer you charge at one time the more voltage is applied to recharge them. I cycle them to keep at least one fully charged and it always is recharged WAY before I kill the current one. In summary, fairly quickly and faster than I require. Your milage may vary.

I would say these are more like a 2 hour battery and then they need to be charged. Same said for the new batteries from manufacturer.

Mine charges in about one hour but my husband had trouble because although he plugged them into his computer they did not charge because his computer was in sleep mode and not on. be sure your computer is on also.

They will be ok. I usually charge mine over night, in the morning they are fully charge. Usually takes couple of hours. Once they are fully charge the charger turns off.

I believe the charge time is two hours. When I received my product both batteries where fully charged though. I bought my flashlight for my job, but barely use it so I am still using the first charged battery.Hopefully this was helpful for you.
