Do they come fully charged or they need charged and if so how long for the first charge and the ones after that?

They had a charge, Lion batteries should never be left discharged. I always charge and discharge several times after initial use.

The one I got was partially charged. I think they take a hour or two to fully charge. But it does work without a problem.

They are fully charged in just a couple hours if they are completely dead. Unfortunately there is no indicator light letting you know when they are fully charged.

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.

No i hvnt needed to i got them and charged them and when i can tell they start to drop off volts i charge them but they work ok last about 4 or more hrs before i notice voltage drop. My mod says they still are half charged but i notice the drop around 60% so i just charge them. They are good for back up so they work ok for me. I use my sony and efest batteries for when iam going out and i bring one of these just incase. But i also vape alot and at 20 or more watts so if u hv a mod thats only 15watts they would prob work verry well. I dont use them in my dna30 because they are button top and hard to get out of device. If u hv any more Q just ask.

I would do one of two things. Charge them for 24 hours. Or send them back. Mine only lasted about 3 charges. That still put them roughly the price of a good disposable battery, but these are not high quality.

I think the answer is yes but they've probably been sitting in a warehouse and have lost some charge. They always need to charge when I initially install them (right after receiving them)

I have had one charged and waiting to be used for a couple months and it's still fully charged so I would charge them in case there is a problem with power conversion overseas.

The initial charge is 6-8 hours. how long mine took after that they charge full with in 1-2 hours lasts me like 3/4 of the day

It takes quite a number of hours. I'm not sure exactly how much, because I plug them in overnight. By morning, they're charged. I'm guessing about 6 hours.

Mine came charged already but they have individual batteries in them if they don't work.

I didn't test if mine were precharged. After removing sticker from top and charging they work great. Super happy with them. Cannot beat the price.

Recharge these anytime. In fact, best to NOT let these run down entirely, as these (unlike Ni-Cad) have no 'memory.'Mainly don't overcharge. These take about a 2 hour charge, and overcharging in an attempt to bring them up to full capacity cause battery 'stress.' You can get the full, more scientific answers to your questions if you Google. Also, remove from charger after charging.

Yes. They come pre-charged. The manufacturer claims that these are better than other rechargeables at keeping their charge on the shelf, but they also suggest that customers who wanted top performance from the batteries might want to charge them fully before first use.

yes, they chare fully in about 2 hours. Camera comes with charger. A full charge takes a lot of pictures (+/- 100 maybe) but we take a LOT of pictures which is why we bought a 2 pack of replacement batteries ($15 w/ free shipping). I hate when a camera runs out of juice and I don't have spare batteries on hand. Hope this helps.

They should be recharged. These batteries may be recharged many times if they are used properly and not left on until they are completely dead.
