Fast shipping, item as advertised. Durability needs to be verified.
V***y (Verifizierter Käufer) –
An unexpectedly good battery. The test showed almost the declared capacity. I recommend before purchasing.
D***v (Verifizierter Käufer) –
The quality needs to be checked over time, how long it will last and how to charge it to avoid overheating or not for too long. And from the outside, it looks like an ordinary battery.
E***k (Verifizierter Käufer) –
Considering that the capacitor inflates the readings, there is somewhere around 3.5-3.6 Amps. Resistance is 17-18 milliohms.
For its price, it will be suitable for low-current devices.
In another, at a lower price, the same quality will be the same, or maybe even better. I took it to spend bonuses.

ATTENTION! ! These are 1700 mAh and not 4000 mAh as advertised…. I was indeed expecting less but still disappointed….
E***e (Verifizierter Käufer) –
The tested capacity is about 3400-3600 mah.
B***r (Verifizierter Käufer) –
Arrived a few days later than the scheduled date. Looks normal. Very curious if it is indeed 4000 mAH per battery. Previous batteries from another seller did not meet the number stated on the battery. These batteries have not been charged or used yet.

Kuugro 18650 4000mah 3.7v batteries that are charged with a charger.
The first charge took 1.5 hours, even though they were charged. Delivery by MeestPosta, 15 days.
Time will tell how long it will last.
