Are these really 3000 mAH batteries?. Can anyone confirm?

Yes...I ordered four sets in November for flashlights I ordered from Amazon . I got the four flashlights I ordered from Amazon but received only one set of batteries with a charger. I was promised the other three sets from the provider but never received them. Good luck if you order them

yes they are but they are not for vaping. they are only like 2.5 amps if i recall correctly.

I ordered these batteries with the charger, but the batteries did npt fit in the charger snugly enough, so the batteries never charged. I sent them back along with the charger, and purchased panasonic #18650 3.7v mahThe panasonic batteries were expensive, but I believe the quality is better. I also purchased the vizeri tactical zoom flash light. Excellent light for the money with a !00& guarantee. I hope this helps.

Well 4000 is bigger than 3000.... But there is currently no such thing as a 4000mah 18650 cell, and the official UltraFire website does not list these, so they must be fake.

I agree with Mr. Young.. mAh is just the capacity and has nothing to do with the actual output.. it's the 2.4v that's important. In theory, this battery should last a but longer than an 800mAh, but battery manufacturer specifications of their battery capacities are not always correct. At the price, these batteries are a great deal!

They are special batteries....3.7 volts and you have to order them online because they do not sell it in the U.S

I just put a magnifying glass to one of 'em and see the statement is not correct... My old eyes have difficulty with fine print, but it looks like 1200 mAh @ 3.6 volts Lithium ion. It measures 1 5/16" long by 5/8" diameter and looks like the ad picture. Please take my apology. I did not mean to report an error. So far, they still look like a good buy and worth the price I paid.

My battery started to last less and less after 5 months of mild use (playing apps for a short time every day or so. No web surfing, no wifi on, unless it was to download an app). I opened it and the battery that was stated as being a "3200mah" battery is in fact a 2200mah battery. The batteries in these are just junk. I found a battery on Aliexpress and when it gets here from China I will try it.

They are not rechargeables. Not sure if they're used. I don't remember. It's been a while. I checked them on a battery tester and they have a full charge.

I haven't tried to measure their capacity,, but they do seem to last longer and take longer to charge than some 3000mah batteries I use

The labels are often fakes. To see if it is real, peel off the label and look at the printing on the metal shell. If it says 2600mah, it is real, or at least as real as you need. If it says 1050mah, or 1000mah or anything other than 2600mah, it is fake. mah is milli-amp hours, the capacity of the battery, realistically, a measure of how long it will last. The original battery is 2600mah, many fakes are labelled as 2600mah but aren't. in theory a 1000mah will last about 40% (less than half!) of the original when it was new. If these really are 2500mah, they are fairly good and close but the real originals were 2600mah. The labels are often fakes.

I have to admit that I bought the batteries for a tool for size. Forgot to check capacity but it looks like at least 1800 mah. Things have happened which has kept me from using the batteries. Sorry can't be more help. Price is right though

No. They're much bigger. They are 3.7 volts compare to AA which is 1.5 volt. Higher mAh too.

There ARE no "REAL" 4000 mAh batteries! That capacity doesn't exist yet! These batteries, PLUS the charger they're being sold with are BOTH garbage!

No. They are 18650 batteries. Probably removed from a used up laptop battery.Ultrafire batteries are crap. You might get lucky, and get a good one, probably not.

I'm not sure if they are or not, they had Chinese(?) writing on them, which doesn't necessarily mean they are counterfeit. They worked for me, but didn't seem to last as long as other Duracell batteries I've purchased.

No, they are 1.2 Volt, 2850 mah ... I use these in my digital camera and they are the most awesome batteries I have ever used!

You can't tell if they are a good deal or not unless you understand the capacity of the battery (usually measured in milliamp hours. AKA Mah). Unfortunatly, Amazon doesn't understand this because most of the specs don't list this peramiter.

I received 150 mAh. The larger number just means it will power more current for along period of time. So they should be Okay as long as they fit your device.
