Skywolfeye Flashlight Headlamp Batteries, 10PCS 5800mAh 18650 Battery Rechargeable 3.7v Li-ion Button Top

second purchase

batteries work as expected

FRAUD alert - there's no capacity higher than 3500 mah in 18650 batteries. These likely test 1000 mah or less - DONT BUY

Across all of the negative reviews for 18650 batteries, the SAME NAMES occur OVER AND OVER! I believe they must be employed by a competing battery manufacturer, or are negative reviews ACTUALLY COMMISSIONED by those companies. I have used SKYWOLFEYE 5800 MAH batteries FOR YEARS, and they have been GREAT! I don't care what number is on the label. All I know is that I can charge them up, put them in 8 different multi-cell flashlights that I keep in various places around my house, and even after a WHOLE YEAR of storage, they light up just as brightly as they did the day I put them in the flashlights. What more can you ask for? I believe that most of the negative reviews are themselves, FAKE reviews. Yes, you have to exercise caution when handling or charging LI-ON batteries, but that is true of ANY LI-ON batteries. You must use a QUALITY micro-processor controlled charger such as those offered by NITECORE. PLUS, I place my charger inside of a LARGE tin container with a lid, and place it on a non-flammable surface. Those are precautions you should take with ANY LI-ON batteries. I am tired of all of the reviews claiming "I TESTED THEM IN A LAB". I don't personally have a "lab", and I certainly couldn't afford to PAY a scientific lab to test a battery. I think it is mostly the negative reviews that are fake. I have used SKYWOLFEYE 18650 batteries for years, and I am more than HAPPY WITH with the performance I get out of them, no matter what it says on the label.
