Works as it should and holds charge. It's a battery, what more can you say?

Works great. I bought a separate charger to charge these two at a time.

After tested, they both only have 2000mAh capacity, not close to 3500mAh advertised.I was wondering and felt too good to be true with that price range.but given the price, mostly 2000mAh is the fit.hopefully they will last.Tried to ask seller but no response so far.

Fast shipping and great price. I ordered the wrong ones so that's my fault but everything was in a nice neat package and arrived really fast.

6pcs 18650 Rechargeable Battery 3500mAhThis review is for the High Capacity 3500mAh Genuine18650 Battery Button Top Battery from Yuntunele. Color Blue ASIN B0CWX67HTDThey are Li-ION subtype INRCells arrived with charges from 3.60V to 3.7VAll cells were fully charged to an ending voltage of 4.2V using an MIBOXER charger. Cells were recharged to that same 4.2V ending voltage using an MIBOXER charger after each discharge test.Cells were tested using a three different loads.A nominal 1A resistive load, discharged until cell voltage dropped below 2.8VA 500mA constant current load, discharged until the cell voltage drops below 2.85V.A 250mA constant current load, discharged until the cell voltage drops below 2.85V.The 1A test was run three times per cell, the 500mA test was run twice per cell and the 250mA test was run once per cell.The best cell managed 1929mAh on the 1A discharge test, the worst cell only provided 1522mAh. The average was 1707mAh. No cell on this test achieved better than 55% of the rated 3500mAh capacity. Cells varied by up to 10% of total capacity.On the 500mA discharge test, the best cell achieved a total of 2044mAh, the worst 1861mAh. The average was 1942mAh. On this test, two cells reached 57% of rated capacity with the rest only achiving 54% of rated capacity.The 250mA discharge test revealed an odd spread in the cells tested. Some cells preformed worse at 250mA discharge rate than they did at the 500mA discharge rate. The best cell managed 2019mAh and the worst 1797mAh, a spread of 51-57% of rated capacity.This is a little more difficult than the test of the 5000mAh cells. While NONE of the cells reached their rated capacity, the cells were quite even in their performance with varying loads and generally averaged 50% of rated capacity under different loads...However, they do not even reach 75% of their rated capacity and are unacceptable. The 3500mAh rating is simply not correct.Do not buy.This set is going back to Amazon on the next UPS truck.--

My solar blink camera was eating batteries. It turns out the rechargeable battery was no longer taking a charge as it was a couple years old when delivered. This item seems to work fine.
