Gearbest is real. The picture of the 18650 cell is real. The printed label stating 5000 mAh is real. However, the advertised capacity is fake. One of the Answers to the Questions on the gearbest page states the capacity to be 1200 mAh. That is probably closer to the truth.
G43…
Its not that its a fake ultrafire, it is real ultrafire…
What everyone here is trying to tell you is that it’s over rated for the mAh spec. As MtnDon said it’s probably only around 1200mAh (or less)
But don’t worry its a common practice for some of the off-brand batteries to have inflated mAh specs.
We just want you to know what you have, some of these low quality batteries could be unsafe. Please be care full not to let the battery voltage drop below 2.5v and don’t overcharge it either.
Do a search on the forum for “fire battery” and start reading…

The battery pictured is “real” in the sense that if you ordered it, GearBest would ship you an Ultrafire battery that says 5000 mAh on the wrapper. The problem is, Ultrafire lies about the capacity of the cells. They will take the cheapest battery they can find, and slap on a lable claiming 5000 mAh. If you were to test one of these batteries, you would be lucky to get an actual capacity of 2000 mAh. Not only do they lie about the capacity, by using bottom-of-the-barrel, potentially recycled cells, these batteries have completely unpredictable discharge characteristics. If you tried to use them in a flashlight drawing 3-4 amps, they might be permanently damaged, or even fail violently.
The current highest capacity 18650 cells are 3500 mAh. All high quality 18650 cells are made by a handful of companies - Samsung, Sanyo/Panasonic, LG, and Sony. Other brands, such as KeepPower and Orbtronic, take these batteries, add a protection circuit, and put their own lable on it, but they are still a Samsung, Sanyo, etc. cell underneath. Also, some flashlight brands may take these batteries, put their own wrapper on it, and slightly inflate the capacity in the process. So if you see a Klarus 3600 mAh battery, that is actually a 3500 mAh battery made by Samsung or Sanyo, but it is still a high quality cell.
But if you see 18650 cells with an advertised capacity of 4000 mAh or above, they are lying, and highly unlikely to be using a high quality cell underneath.

Thank you!
Have been noting lately some really weird, even ridiculous attempts to paint GearBest in dark colors… 
Man, what are you doing? On whose behalf are you doing this? 
Allow me to correct you.
That’s Panasonic NCR18650G 3600 mAh (G and not well known GA 3500mAh), mostly bought by Tesla so it’s hard to find them on market. You can still get them in some repacks (keeppower, klarus, olight, orbtronic … ), tho.
There’s not much capacity difference compared to 3500mAh cells, but I am correcting you for the sake of accuracy anyway. Klarus does not advertise this falsely and then just rewrap Sanyo NCR18650GA 3500mAh. They use here Panasonic NCR18650G 3600mAh.
There’s another example of Keeppower “18650G” 3600 mAh repack:
Many sellers that don’t specialize in batteries, from GearBest to Amazon, sell Ultrafire and other very questionable brands. That’s not an issue unique to GearBest. In fact, these sites sometimes have problems with 3rd party sellers taking old, crappy batteries and putting a new Samsung/LG/Panasonic wrapper on them and selling them as new, higher capacity batteries. If you really want to be safe when it comes to batteries, I would recommend sticking to places that specialize in them. Illumn, IMR Batteries, Li-Ion Wholesale, and a few others in the United States, and nkon.com in Europe, to name a few. But those places also tend to be more expensive.
The other option is to get an analyzing charger - Bilakos frequently posts deals on the Liitokala Lii 500 and Zanflare C4. These chargers can measure the capacity of the cells. So you can order (name brand - Samsung/Sony/LG/etc.) batteries from GearBest or BangGood, and just run a test cycle on them. As long as the reported capacity agrees with the claimed capacity, you should be fine.
As far as safety… Will these Ultrafire batteries kill you? Doubtful. But start a fire? It might not be likely, but I would not rule out the possibility. The cheap batteries they use may or may not include the safety mechanisms that are incorporated in the high quality Samsung/Sony/etc. batteries. You just don’t know, and it’s not worth the risk.
Looks like G34 already took the risk, the damage is obvious
If you’re talking about the single battery tube version, it’s not great. It’s too short for button tops and even flat tops are tight. I ordered 3 and 1 didn’t work. Didn’t load test, just made sure they would power up a small device. For the price, I wouldn’t expect much or plan to use for anything other than last resort. I have Tomo power banks with LCD current display for normal use.

Thanks for the correction. Completely forgot the NCR18650G was thing, because you never see it for sale anywhere. Where are these manufacturers sourcing those, if stores focusing on batteries, like Illumn or IMR Batteries, don’t even carry them?
That’s what happens when you are mass producing in a large scale.
The first production batches usually don’t provide any income, but once the R&D expenses are covered, you are essentially left with a minimal production cost.
Soshine Portable 18650 Battery Holder - The Code you entered has expired.
OMG! That was a good one 
Wish you were that lucky with the gray mass
Anyway, welcome back again when they eventually block you for idiotic trolling
The more people who would report G43 as ‘rude’ the better off we would all be.
— I am going to be blunt here. My apologies. Please do not take offence.
Your posts could be considered trolling.
Your posts are off topic. They should be in another thread.
This thread is for deals negotiated by bilakos10. He does not work for Gearbest.
As far as I know he has never promoted or offered a coupon code for UltraFire “5000mAh” batteries.
It is well known here that the UltraFire batteries are not good. If you had done some reasearch or just asked, someone would have told you.
Gearbest say these batteries are really about 1200mAh:
Q
Tell me, what the real capacity of these batteries?
