$0.00


★★★★★ A 4pcs Ultrafire 18650 3000 mAh review will not answer these 33 questions. Get the truth from people who own a 4pcs Ultrafire 18650 3000 mAh, including the fact that it won't...

QUESTION: HOW LONG AM I SUPPOSED TO CHARGE THESE? I GOT THEM TODAY, AND PUT TWO IN THE CHARGER AT 10AM. AT 5PM THE LIGHT IS STILL RED. ISN'T THAT RIDICULOUS?
The CHARGER OUTPUT controls how fast a battery charges. Time is calculated using this formula: Battery mAh divided by charger output in mAh. If a battery is completely discharged and needs a full charge it will take this long for the package shown for this purchase: 3,000 mAh battery, 600 mAh charger output. 3,000 / 600 = 5 hours. BUT WAIT! If charging 2 batteries, that is 6,000 mAh / 600 mAh charger output. So, the answer is 10 hours per pair if the charger is truly putting out 600 mAh. If it takes more time, it is most likely the fault of the charger.
I always just do mine over night so I don't really know the exact time it takes
Yes, it is totally ridiculous but I have to do the same thing!!!
YES, it's ridiculous. And it's even doubly bad, because these batteries are LESS THAN HALF of the capacity that's on the label! In a NORMAL charger, (@ 1A current) these would finish the charge in LESS THAN 1 HOUR!! This also tells you that the charger is extremely weak. But it MIGHT also mean that the batteries are bad, and cannot be charged! This is very dangerous if that is the case.
It takes a long time to charge them. At least 12 hours
The light doesn't goes out, it's just a indicator showing the batteries are charging but they should be charged by now.
The light will go green it takes 12 hours or better to charge them depending on the state of discharge
Hi,you charged what battery? If like you buy the battery so about five hours, but don't worry,charger charging is red.Charger full is green,is have protected
Doug , I'm sorry but I have not used the charger yet . I put disposable batteries in my flashlights.
No it may take up to 10 hours depending on how long they were in storage

QUESTION: WOULD THESE FIT IN A BOX MOD
very good
this is the 18650 battery and the 18650 battery charger.this battery is a little longer than AA battery
No I tried with a demitri style box mod and a lotus t80 neither fit they have a small nub on the top of the battery making it to big but if you have a tube style Mech mod then it may work
You need the flat top 18650 3.7v battery

QUESTION: 6.5 CM X 1.7 CM DIAMETER, IS THIS A UNIQUE SIZE - MY WEAK MEMORY IS I HAVE A LED 1 CELL POCKET LIGHT THAT CAN BE URUN 0N EITHER A 1.3 V AA MIHALIDE?
I'm not sure I use these types of batteries for my vape mod.
It is a unique size and 3.7v
Confused by your question. Although if your pocket light only accepts a 1.2v rechargeable or a 1.5v disposable (alkaline) then a 18650 won't work.
the 18650 li-ion battery is approximately 18.46mm diam. x 64.75 mm .717" diam. x2.5" they are approximately 1.37 v fully charged. 1.82cm diam. x 6.35cm . or slightly longer if you measure to the very tip about 6.55 cm long. diam. might be slightly larger as shown?
the 18650 li-ion battery is approximately 18.46mm diam. x 64.75 mm .717" diam. x2.5" they are approximately 4.1 volts fully charged. 1.82cm diam. x 6.35cm . or slightly longer if you measure to the very tip about 6.55 cm long. diam. might be slightly larger as shown? while the battery may fit it is too high of a voltage for 1.3volts without some other modifications. Also gets very hot if operated at high current. work well on robotics and model cars. A AA NIMH battery is 1.2 volt rating and is 1.42 cm diam. x 5.08 cm long approximately. So it probably doesn't fit and is the wrong battery voltage for your supplication. 18650 is good for light weight higher voltage and power and medium use duration.
18650 battery is a 3.7V,not1.3V Thank you!

QUESTION: HOW MUCH DOES EACH BATTERY WEIGH IN GRAMS?
Is about 45g (+- 8g)
I did not weigh them but they are only like 10grams and not the 40 ish grams they should be. And there defiently not ment to vape with these battries are ment for flashlights if that. Hope it helps and if your looking for battries for vaping make sure to spend the extra money for some good ones.

QUESTION: HOW LONG TO CHARGE BATTERIES?
Depends on your charger, and how much capacity the batteries actually have (most Ultrafire batteries have false mAh markings). I wouldn't buy these, all except for one I've ever heard of were bad batteries, and even that purchaser found the capacity was 2000 some mAh. I'd find some Panasonic 3100 or 3400mAh protected batteries instead, these Ultrafires are not worth it.
These are facile batteries and charging is difficult to pin down. The first time I charged them it was maybe about and hour, but they were not completely drained either. They should not be over charged are over used in my experience. They get really warm in the torches and will at this point discharge rather fast. I try and watch them when charging because I really don't trust them, when the Green light comes on I take them off the charger quickly, hope this helps.. PS: this is the first time I have had all eight being in perfect working order since I started using them.
I had the same question after i received the charger, there were no instructions with it. It came wraped in a peice of plastic. I ended up purchasing a new charger with a digital guage so i could tell if the battery was fully charged.
2-4 hours
I was told to take them off the charger as soon as the light turned green. Don't leave them on the charger.
around 2 hours, but I never let them go all the way dead
#ultrafire

QUESTION: HOW LONG IT TAKES TO CHARGED THE BATTERIES?
3-4 hours but charge only when they are really not working they last for like maybe 2 weeks for me and i use it alot
I takes about 6 hours or so.I charge them at night.
It usually takes 4-6 hours to charge the batteries.Thank you!
Too long and they wont hold the charge
#ultrafire

QUESTION: A LITTLE CONFUSED HERE AND WANTED SOMETHING CLARIFIED: AREN'T DOUBLE A BATTERIES SUPPOSED TO BE 1.5V? SO WHY ARE THESE 3.7 V? DO THEY MAKE 1.5V?
It's not a double A battery... It's 18650, the one you use to a surefire flashlight or sometimes it works on E-cig aswell...
the voltage is 3.7V
yes AA are 1.5 V so are AAA and C and D's. However when used in some higher voltage equipment and flash lights the 3.7v 18650 are used instead of 3 AAA.
These are not Double A batteries. Or else it would have said AA batteries. These are much larger and are for tactical flashlights and such
These are not Double A batteries. Or else it would have said AA batteries. These are much larger and are for tactical flashlights and such
18650 is not a 1.5V battery in shape ma be but is longer and fatter than a AA battery. I is used in high power flash lights and other devices that require it's high amperage to power them. I bought this item only to find out the batteries will not hold the charge and the charger broke after only two months. If you are looking for 18650 batteries look elsewhere.
They are nor AA batteries. I believe they are specifically for Ultra fire
the voltage is 3.7V
#ultrafire

QUESTION: WHEN I PUT BATTERIES IN TO CHARGE, THE RED LIGHT FLASHES CONSTANTLY. ANYBODY KNOW WHAT THIS MEANS?
Battery no good
Flashes constantly.
Unless the batteries were installed incorrectly, the red blinking may indicate that it's charging. It should go to green once full charged
They keep charging
#ultrafire

QUESTION: THESE RED ULTRAFIRE BATTERIES COMPARED TO BLUE ULTRAFIRE BATTERIES?
the reds are cheap. dont waste your time
These are fakes (most likely recycled laptop batteries)...one of the 8 I bought were dead, there is no circuit protection, and label contains a spelling error. If you want cheap cells, these are for you...just don't expect anything special.
The same, look for the mAh rating same performace.
Check the Mah number with the battery. The higher the number the longer they with hold a charge. The red are usually 3000 Mah. The light blue are usually1200-1800 Mah. I have seen a darker blue with 3600 Mah. The black and gold are usually 4000 Mah. The logic here is the higher the number the longer the battery should last per charge and I assume the more charges it will take during its life. I have some red and some black (3000 and 4000). I have charged some up to 40 or 50 times and they still run strong and hold their charge when not in use for a good period. A 900lm/1000lm rated light will run on high power for at least an hour straight on the red and 75+ minutes on the black. I hope that is helpful.
I am sorry, but I have never the blue ones. Richard
#ultrafire

QUESTION: CAN THEY PUT OUT 20A
NO. 1,000 mAh = 1 amp / 110 watts under brand new conditions for a battery. 3,000 MAh = 3 amps MAX when new, & it goes downhill from there each time it is charged. YES, 7 could if wired in series configuration; = 21 amps.
the voltage is 3.7V
Rated at 3000ma/h so i doubt it
#ultrafire

QUESTION: WILL THESE WORK FOR AN ISTICK 100 WATT AND SUB NANO KIT?
No. They suck! And if you run them through an analyzer, you'll see the capacity is less than 1000mAh, AND they're UNPROTECTED! You might as well flush your money down the toilet! A pack of four (PROTECTED) 3400mAh 18650 batteries SHOULD cost you a MINIMUM of $45. Plus, a good (2 slot) charger will be an extra $15. THAT is how you spend money WISELY on rechargeable batteries. They are safe...they are reliable...they'll last much longer between charges, and they'll be good for several years.
I am sorry that I am not familiar with what you're referring to
They will work for the istick100w but could be very dangerous and they will not work very long and will not even fire at 100w. They are low drain battries and are not ment for regulated mods and defiently not for unregulated mods.
These batteries suck. Most likely pulled from a laptop and re branded. Do a YouTube search on this battery and you will see, they suck.
Do not buy these for VAPING they are ment for flashlights and are LOWDRAIN battries.
hi ,this battery the volatge is 3.7V
#ultrafire

QUESTION: DOES THIS CHARGER USE A BRITISH OR AMERICAN PLUG?
Yes,us plug
American plug is used with this charger.
yes
The plug fits U.S. standard 110 volt receptacle. According to specs on back it will also work on 220 volts at 50 or 60 cycle current.
American
#ultrafire

QUESTION: IS THE RED LIGHT SUPPOSED TO FLASH
No!! It's possible that you might have a bad battery. Because the rate and cost just order more:). Good luck!!!
Remember any battery can suffer from "memory loss"
I'm not fully familiar with this specific charger, more the batteries. Typically with li-ion and other battery chargers the following will happen: Solid red light, the battery is charging, and when solid green will be finished charging. Red light flashing fast, bad battery or connection to charger, slow red flash, charging.
Only when charging , when it's fully charge it will stop.
From all I can tell, he red light is supposed to be solid when charging. If flashing, it could indicate a charging error (bad/defective battery), or a faulty charger. I would suspect the battery first. Good luck.
I just plugged my charger in with two batteries. Light is solid red. Will turn to green when charged
Mr. Huffine's response is correct..............solid red until charged. Charging may take as long as 48 hrs.
Yes while its charging

QUESTION: A LOT OF BAD REVIEWS, BUT IM ASKING ANYWAY... HOW WILL THIS GO ON THE SNOW WOLF?
Snow wolf wattage is to high I don't know if this works
No,I don't recommend this product
I have a sígalei 150w temperature control and I do not recommend this product!100%
#ultrafire

QUESTION: CAN YOU USE REGULAR BATTERIES WITH THIS FLASHLIGHT IF YOU'RE NOT RECHARGING IT
If it uses 18 650 batteries then yes they are not flat top but they do die very quickly that is why I wrote a bad response but after a couple days of using them there seems to be working well now
Some flashlights come with a battery holder or with a plastic sleeve to use the 18650 battery.
You can only charge the 18650 batteries
three triple a batteries and the special holder that combines them make them about the size of an 18650 battery, but just a little bigger. So some flashlights are made to work with a 18650 battery and sleeve and they can also use the 3 triple a's with special combiner. Some flashlight battery holder are just slightly smaller and will only take the 18650 battery without sleeve. check the product specs closely. I just bought some extra 18650 batteries. Love them. bright, powerful and regargeable. good luck.
What flashlight are you talking about? There isn't one associated with this set.

QUESTION: WILL THIS WORK WITH A ANUBIS MOD PEN
Battery voltage is 3.7v
Yes,but this batteries are the worst batteries in the market!
No. These are NOT good for e cig
I'm not familiar with that pen, but if it takes 2 CR123 batteries, these will work.
#ultrafire

QUESTION: CAN I USE THIS CHARGE FOR MY NIMH AA BATTERIES?
I have never tried to do that as I have a seperate charger for all my other batteries. Since this charger came with the batteries thats what I only use them for. You could try but I really dont know if it will have any bad effect on your AA batteries.
No
I would only use this charger for the size of lithium ion rechargeable batteries that it was intended to be used with. Better to be safe than sorry. Could possibly damage batteries or charger.
No. This is for charging Lithium Ion batteries which are 3.75 Volts. your niMH batteries are 1.25 Volts.
you must never never switch battery chargers. use wrong charger and you could have a fire or explosion. always use the charger that came with the batteries or purchase a charger rated for your batteries.

QUESTION: ARE THESE REAL ULTRAFIRE BATTERIES? ULTRAFIRE.NET SAYS NOT TO BUY ANY ULTRAFIRE BATTERIES FROM AMAZON DUE TO THEM BEING FAKE!!!!
yes
MOST ARE. Amazon has lousy fraud controls. I am not sure about these.
#ultrafire

QUESTION: DOES THE BATTERY CHARGER STOP CHARGING THE BATTERY'S AUTOMATICALLY AFTER THE BATTERY'S ARE FULLY CHARGED?
I'm not sure it stays on a green light but they hold a lot of charge and work great
The battery charger will stop to work when the battery's are fully charged.But,you should take they out are the best.
When you plug the charger into the wall there is a red light on the charger. When you put the batteries in the charger the light is red until about 2 hours then the light turns green telling you it is charged
chargering is red,Chargers full is green
The charger light changes to green when the battery is finished charging, I'm not sure if it stops the process, I just remove the batteries when I see it's green.

QUESTION: WILL THIS WORK FOR THE SUB BOX MINI
Noooope
I don't know the answer to your question, but let me tell you don't buy them! They are bad, will not hold a charge and the charger is a total piece junk. It broke at the plug and stopped working. It took 2 days to charge the batteries when it was working.
the battery voltageis3.7v
I personally don't know if it were to work on that particle electronics but I suggest to read the description carefully for the batteries included or not but I had to buy these separate and if the seller did not post what type of batteries specific for my device i probably would have put the wrong batteries in. So I hope this helps and so far I have had no problems with the product above.
#ultrafire

QUESTION: SPECS ON CR123A
CR123A is a type that can not rechargerable;size is the same as the 18650
Batteries to be charged specific to charger. works well for me. I have no problems with batteries or charger.
#ultrafire

QUESTION: SO, I GET THAT THE BATTERIES SUCK (I HAVE SOME GOOD ONES ORDERED) BUT HOW GOOD OF A CHARGER IS THIS?
The charger has worked fine for me.
No complaints after seven months of daily use.
not good.
Its bad, takes about a day to charge 3000 mAh batteries
Take note that no two pictures ever match. The one that's pictured on this page is much different from the one in the ad. Basically, it's VERY VERY slow...and personally, I wouldn't trust it. I suggest a Nitecore UM20. It's about 15 bucks. It does two at a time, AND at 1A!! And if you use it to charge THESE batteries, it'll complete the job in less than 2 hours! Better 3400mAh batteries would take around 4 hours. You won't regret it.
#ultrafire

QUESTION: DOES THE BATTERY CHARGER, CHARGE 2 OR 4 BATTERIES?
two batteries and they work great too me
It charges only two at a time.
Dont buys these they are fake and dont work
#ultrafire

QUESTION: ARE THESE BATTERIES SAFE FOR A HIGH DRAIN DEVICE LIKE A 60WATT I STICK?
I don't know if they are safe, but the charger isn't safe. Mine started smoking and the spring melted. It did last for about 4 days though.. The batteries are terrible too. Don't waste your money. I like a deal as much as the next guy, but this whole package is garbage.
No. These 18650's are UNprotected and do not perform well when discharged at a high rate. They are also LESS than 3000mAh. It's recommended you get protected batteries only, and stick with reliable brands, such as Orbtronic, Olight, Nitecore or Panasonic.
Just don't waste your money on these please.
Yes, extremely reliable

QUESTION: DOES THIS BATTERY WORK ON THE SUBOX MINI?

QUESTION: ARE THESE FLAT TOP OR BUTTON TOP BATTERIES?
button Top
Button top. They do NOT fit in most regulated mods
There top is like a AA battery except they are about three times the size. PS mine came fully charged. Hope that helped you.
Button top, but not a standard size battery .
