Excellent batteries, I have had them for over 2 years in my electronic vape and I still haven't needed to replace them. Frequent use and charging at least once a day.

For the Innokin krona r electronic with mild use and at 10w it barely lasts 8 hours and I have bought 4. Waste of money

After just a few literal recharges, the battery is useless! I was amazed at how short its lifespan was and what a waste of money buying them is!

I put them in a rechargeable lithium vacuum cleaner after its own noname batteries died after 7 years of use...
I made three such vacuum cleaners in parallel...
In two of them, the situation was like this and I put vtc6, and in one I put these lg hg2...
The vacuum cleaners with the vtc6 have more power... You can see the difference in power...
As for duration, I don't know yet... Time will tell... Or how long they'll last...
As for power, my preference is for sony...
In a power bank, though, where I've used other lg s3 I think, you can't really call them a bargain... In general, lg batteries are ok, they last for years but don't have much power or duration, and compared to noname they're better, but overall they're average as a branded product... For power banks I use Samsung for capacity, but in terms of longevity they don't last long...
That's all...

Good Battery, just because I buy 5-6 every year for the Electronic Cigarettes - which I have 3 in total - one of them is a dual battery - it does its job.

The batteries they sent me from this particular store were either defective or old; from the beginning, they had no lifespan, while in the past I have purchased these specific ones from another store

The batteries we buy new have some charge. If we immediately put them in the charger and they become full, our charger shows us how many mah it took to charge them and not the total capacity of the battery. To see about 90% of the full capacity of the battery, it must be emptied using it in the mod.

Reminder...our charger shows us how many mah it charged and only that.
So only empty the batteries in the charger.

The batteries never charge to their maximum voltage (4.2v) and after being removed from the charger, they discharge on their own. Also, their capacity is nowhere near the advertised 3000mAh, as I discharged them from 4.18v to 3v at 1A and the results are shown in the following PHOTOGRAPH. The batteries are so fake that their weight is much lighter than the authentic ones, and there is no way you can draw 20A MAX from them because I am only drawing 1A and the voltage of the element drops from 4.18v to 3.7V. THEY ARE ALL LIKE THIS. Unacceptable product, it's a joke. DO NOT BUY FROM MR.VAPES. If you plan on using this for vaping KNOW THAT ITS DANGEROUS.

Purchase on 29/3 from the beginning MO 1600mah and both batteries the same.
The first one went off in the 3rd month, and the second one in the 4th month.
In the end, they must have fake batteries.
It should be noted that I bought them because I had purchased 4 genuine ones and they started to deteriorate after a year and a half

mediocre performance, I don't know generally LG concerns me that I bought it, I was not satisfied, my TV burned twice, the washing machine burned the electronics, the phone screen broke, and this is mediocre, I will not buy LG again

After a year, they dropped to 1500 to 1700 mAh. With daily alternating use and the five that I bought, vaping at around 30 watts. With 1500 and 1700, you last for two to three hours, maybe four at most, depending on the puffs. We're always talking about 30, at most 40 watts. If you ultimately use resistances below 20 watts, they are worth their money and can last you two years, considering my personal experience. I don't know how much their discharge is affected by use afterwards, and how accurate my method was for the final judgment and review. I'm not an expert or an electronic engineer. I'm just sharing my experience, as I said.

Finally, you get what you pay for!
Compared to the Andowl Q-DC3000, which is half the price, they last twice as long and take much longer to charge.
Based on the data, the LG HG2 has a capacity of only 3000mAh instead of the 8800mAh of the Andowl Q-DC3000.
If they last at least 300-400 charges, it will also receive 5 stars!

All those with the sticker are fake.
The codes for the genuine ones:

First code: LGDBHG21865
divided into LG-D-B-HG2-1865
LG: Brand name
D: country (A, C, D from Korea; E, G from Nanjing, China)
B: capacity (A: 0-2400mAh; B: more than 2400mAh; S3=2200mAh; A4=2400mAh; B3=2600mAh; C1=2800mAh)
HG2: model
1865: size

Second code: S128K082AG
divided into S-128-K08-2-AG
S: year (A=2001; B=2002; ... O=2015; P=2016; Q=2017; R=2018, S=2019, etc...)
128: day of the year (128th day of S=2019)
K08: batch number
2: product number
AG: LG's internal code

Unfortunately, the capacity is half of what they claim.
They are not worth the 3.7 euros I paid. Why? Because they are fooling people.

I bought two, but both are around 2000mAh, so only with the addition of the second one, I get through the day. Prefer something else. One star for each!!!

I bought 7 pieces for an e-cigarette and all 7 charge at 2000-2300mah in 3 hours, they need replacement. I would suggest choosing some other ones unless I got a fake batch.

I bought 2 pieces, one of them I was able to charge with my e-cigarette. The other one had a problem (it wouldn't charge at all). I had to buy a charger to see what was happening, the XTAR VC2, and when I put it on, it showed completely discharged (all at 0V). After a while, it recovered and started charging the battery, but unfortunately it only charges up to 2109mAh and not the advertised 3000mAh! Disappointed...

I don't know if it's the batch, but I bought 6 pieces and they are all garbage.
I use them twice as much in an electronic cigarette device and they don't produce 24 hours of vapor with the same usage as before!
I have been using the same batteries for 6 years, changing them every 2 years approximately, and the previous batches lasted me at least 2 days of vaping!

Unfortunately, I am also one of those whose capacity is NOT what is advertised, but closer to 1500-1800

Bought from a well-known e-cigarette store. Both the batteries and the store are unacceptable. Battery code LGABHG21865 with a capacity of 2000 mAh, but barely reaches that and after replacing them with a thousand troubles, they still have the same capacity, one at 2100 and the other at 2050. Unacceptable batteries and they sell them for 10 euros.

I used it on my e-cigarette and it lasted exactly two months, then it stopped charging and had to be recycled

Nice battery for the price. Holds up charge well even after multiple recharges. Durable and relatively safer than many cheap counterparts

I wanted them for my electronic...while they also brought me a USB cable to charge these rechargeable batteries inside my electronic device, when I tried to do it, they wouldn't charge at all and they told me that I had to charge them with an external charger which obviously I had to buy separately, while some customers didn't have this issue.

Not something special. I put it in a solar LED light and didn't see any difference from the previous one that broke. Works like the broken one I have. Lasts very little

One of the best 18650 batteries.
They are not authentic LG (since LG does not produce branded batteries), they do not have a capacity of 3000mAh (they are around 2500-2600 maximum) but they are equally durable over time and in use.
One of the most ideal for electronic cigarettes... and when they are slightly depleted in demanding use of the e-cigarette (after a while+), you can continue to use them in a flashlight or 18650 power bank case...
Attention, there are imitations circulating!

In no case are they authentic, they charge up to 2000 or 2100 at most, I bought 2 and both did the same. Stay away from this product.

The batteries are the worst thing I have ever bought in my life. From the advertised 3000mAh, I charge them with a new XTAR X4 external charger and they only have a capacity of 1250mAh. I use them for an electronic cigarette and both of them barely last two hours, while on the first day they lasted four hours each. In short, they are useless.

TODAY IS THE THIRD DAY SINCE I BOUGHT THEM. I PUT THEM TO CHARGE AND THEY ONLY OUTPUT 816mAh, LASTING AT MOST 20 TO 30 MINUTES.

For use <= 60Watt the batteries are excellent, with longer usage duration than the Sony ones.
For higher Wattage, I would recommend the Sony ones

So I have had them for 8 months now with 2 Smok E-Priv batteries and TFV12 Prince atomizer with 0.6 resistance and 85Watt. The first 6 months they had a very satisfactory performance both in terms of power and battery life and I don't even charge them externally, but on the mod itself due to frequent movements between home, work, coffee, etc. The last 2 months, the battery life has decreased quite a bit at high wattage, however, with the second atomizer I have (eleaf melo 4 and 0.15 mesh resistance at 52watt), the battery life is still very good. So they struggle at high wattage now, but they hold up well at low wattage. (This specific Smok mod has an amazing chipset and great power, so maybe it also has good energy management because there have been some things said about many eleaf mods and battery management.)

I used them in a mod for an electronic cigarette. Excellent, very close to their nominal capacity. For this use, only these ones were, the Samsung 30q and the VTC6 were very close to each other, safe, none of them disappointed me. Just as many people say in the comments, be careful with the fakes!
