Depending on the amount they were discharged from 30 minutes to about 2 and a half hours

Takes around 6 hours if you recharge all 4 at the same time about 3 hours if you only charge 2

Depends on the MAh of the batteries, how much they are drained. My 3100 Mah drained are about 6hrs, 200Mah about 3 1/2 to 4 hrs.

Mine are usually fully charged in about a couple of hours. My charger has a red and green light. Within 2 hours the green light comes on. A man across the street from me is a paramedic. He said he had been using his flashlight over a year without charging it. I just usually recharge mine on the first of every month.

They aren't even 4000mah @ 500ma discharge rate. They don't even have the (advertized) capacity of 18650's. After a few charge/discharge cycles they (4 cells) average out at about 3150mAh. The lower the price, the more creative the advertizing.On my charger the mah in is only about 3200mah. Did they not say the 6000mah was TOTAL for the two batteries.

You need to purchase batteries that are marked model no. 18650. Try to purchase name brand batteries and a charger. The battery should charge in 1 hour. I have tried aftermarket batteries but they seem to take about 4 to 5 hours to completely charge.

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.

Each battery will last 5 to 7 minutes it will take 10 to 15 minutes to charge the batteries

All batteries are different, charge times vary, id say a few hours to charge my sony vct4 18650s. Hope that helps

And to answer the charge question they take 4+ hours or so to charge with this charger (which wasn't a great charger) I now use an efest ELUC charger it was $35 and it charges a standard 18650 in about 40 min to an hour

The only truly to know that the batteries are fully charged is when the LED on the charger is green. It takes about 3 hrs. to fully recharge.

No. An 18650 is a rechargeable battery that takes the place of two CR123A batteries

(4) Four 18650 batteries of different capacities can be charged at once. It is a two bank system so 4 cells will take about twice as long as 1 cell to fully 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.

Sorry about the delayed answer. . . 3 hours on high beam is what my owners manual specs say, and 97 hours on lowest setting. I assume this is with the 18650 rechargeable battery and not on the AAA batteries. Hope this helps.. .

When it is set to 12amp charge they say it takes 14 hours from empty. I rarely run my batteries to empty so I am able to recharge my batteries overnight - about 8-10 hours depending on how low my battery level is.

The battery is a 18650, they are on amazon, just one thing some of the batteries have a pcb which makes it bigger, and will not fit, ive used the 3.7v deep blue 5000 mah and they work 2 for five i believe. And it should stop holding a good or normal charge, maybe wont charge at all, but there is an amount of recharge cycles that the company should have recommended.

Hi. The replacement batteres are Li-ion rechargeable 18650. These are 3.6v, should be 3000mA.These are readily available with a charger through Amazon- I bought several sets and have had good luck.
