The batteries are for the trash can!! Don't even bother buying!
After about a month of use in a Led flashlight, all the liquids leaked out!
It's a matter of having only 200mah this specific one!

I bought it for 2.50€. It is definitely not 8800mAh, but it works perfectly fine for a solar light!

The 8800mAh are actually only 800mAh!
I added two in a row to reach 8V.
Replaced a 7.5V 1500mAh battery where the device initially lasted 1 hour and 20 minutes!
With the two new theoretically 8800mAh batteries, the device only lasts 1 hour!
Of course, the price is quite low, but I do not recommend buying it!

Update: In the second charge that didn't even last 5 minutes, the device shuts down in 1 minute. Money wasted!

Fake. I have a charger that measures the mAh of each battery. Out of the 4 that I have, two were at 300!!!!!! And the other two were at 600 something!!!!!!!
In other words, even the damaged ones that you take for recycling don't have such low mAh.
First of all, just the fact that they claim to have 8800 mAh is a scam. I have never had a battery in my hands that goes above 3600-3800. These capacities simply don't exist and they sell us smoke. If you look, all the expensive 18650 batteries are around 3000 something, it's not a coincidence.
It's a shame that such products exist to clean up the market and not fool the customers.
Write reviews so that we know what we are buying and so that some people don't get rich off our ignorance.

I bought it for a lens that I have, its price was competitive, now its durability will show over time...

These batteries are NOT SUITABLE FOR ELECTRONIC CIGARETTES as there is a significant risk (at least 30%) of serious injury (battery explosion) if used in an Electronic Cigarette mod. They are only suitable for slow discharge devices such as flashlights.

For garbage!!!! I bought 2, I was probably unlucky haha. They don't even charge. Neither in the mod nor in the charger. In the charger, one reached 700 mAh and the other 32. Both were done after the first puff. Great success.... Classic case of... cheapness eats the product!!
