In my experience. I know a lot of people swear by these. I've owned two 18650 batts in the last couple of years. Both dead after a 4-5 month period. My recent 18490 that I bought two months ago just died on me. I was using it with a kick. Now it won't charge.
Meanwhile my UltraFire 18650 is still going strong after two years.
I need a new recommendation for IMR batteries.
