3.7V High Capacity 18650 12800mWh Lithium Battery for Flashlight PowerBank Fan

Very good batteries.

600mwh

Very good batteries.

600mwh

This is not the first time I buy. Good battery, everything works, I didn’t measure the capacity, it feels normal (if you soberly evaluate such devices, don’t expect miracles). Carefully choose, there are 2 types of contacts, the difference in size is not significant, but it is there.

The battery does not hold a charge. It discharges quickly, compared to the old one, even with a small consumption (the load is a household FM receiver Rolton Portable Speaker). I charged it several times, the result did not change.

I checked the voltage within 4.03 / 4.06 volts, connected it to USB charging through the doctor, it takes the charge, after a full charge I find out the real capacity.

The device showed 4.6 volts - I think it will work if there was no self-discharge on the road... Thank you for a good (I think) product...

Put it on charge. After five minutes the indicator shows full charge. This is from zero. They run down as quickly as they charge. I do not recommend it.

The battery arrived working, charged to 80 percent. The battery capacity is overstated in the description and on the battery by 25 percent.

The battery arrived fully charged. The capacity matches the description. I purchased it to install it in an LED headlamp.

The battery holds the charger, the phone charges only 20-30% (phone 3500mah) and the battery is 12800 as it is?

The batteries are not what I need. These are thick and big. I have nothing to use them on. I made a mistake in choosing

Really capacious battery. The damn Sven receiver doesn't have to be put on charge every day now...

I can’t rate it, the fan broke a few days after I received it, and the battery arrived late😕

This is absolute crap, I put it on the speaker and it lasted for 2 hours. The original battery worked for 5 hours.

An ordinary battery of small capacity. Capacity 900mAh, weight 27g, resistance high, 76mOm.

The battery is working, but what kind of battery is unknown. There are no markings on the battery.

The battery is good, I buy it 2 times, v-4.06. EMF is about 9-10 A, in the last purchase there were up to 14 A

After testing, the capacity is 780-820 mAh, instead of the stated 12800 mAh

Took as a replacement. But, nothing worked out, it works the same. The problem is not in the battery

Excellent battery, 4 hours of discharge in the lamp did not reach a full discharge.

The fan started working, it could have been equipped with a battery from the start

Arrived on time. Whole without damage. Everything is as in the picture. Satisfied with the order

The batteries I received didn't last very long. Charged at 100 percent 4 volts. Thank you

Excellent batteries. Be careful when choosing a model (contact form)

The goods arrived, very well packaged. Haven't used it for its intended purpose yet.

Complete deception. The battery does not charge to the specified values. Only up to 900.

Very pleased, everything arrived on time and in good condition I am very pleased

Complete crap, they don't work at all and don't charge. Money down the drain.

The parameters are 10 TIMES lower. DOES NOT MATCH THE SPECIFICATIONS!!!!

Excellent quality batteries, arrived in neat packaging!

This is a scam, the capacity is three times less than stated.

I put the charge on the flashlight, the batteries are good, not bad

Total crap, see it all yourself in the photo, the stated 12800 is not there

Excellent battery lasts for a day almost constantly on

Wanted a battery for a screwdriver, but bought an ordinary battery...

Does not match the description. Battery capacity is underestimated.

All received thank you very much. It remains only to try

Botareiki is good, thank you, I will order more later.

The battery says 12800mwh but in reality it is 600mwh

I haven’t checked yet because I’m waiting for the fourth, apparently because of the numbers

The battery is great, fits Chinese fans.

The battery capacity is not 12800 mAh, but much less

Goods that paid for did not arrive... Didn't want to quibble

Battery 🔋 received, haven't used yet. Thank you!!!

I got what I ordered. I had no big illusions.

Does not correspond to the description, the capacity is greatly overestimated.

I haven't tested them yet, they are too light for such a capacity.

Once they are discharged they will not charge anymore.

everything is fine, the fan is working

Works great in a flashlight. I recommend to all.

Received the product. Works great. Recommend.

I’m buying it again for future use, maybe it will come in handy.

This is not the first time I have ordered an excellent product.

It will go to the lantern, sits very quickly.

Break down quickly, don't hold a charge

The battery doesn't work, and there's nowhere to charge it

Not as capacious as stated. Works.

The battery works well. I recommend

The batteries arrived dead and won't charge.

The amperes do not match the stated ones.

832mah I wanted twice as much...

Does not meet specifications.

Unfortunately, it discharges quickly.
