JetBeam PC10, and my Sunwayman M11R Ti Sirius titanium light, where they give excellent performance. I recharge on a Nitecore i4 4-bay Intellicharger, newly updated edition. It's amazing how much light the high and turbo modes put out on my EC1 on these batteries considering how compact the light is. I've been using them intensively for about six months and have detected no drop off yet in power. My ZTS Pulse Load battery tester also shows these are still at 100% after charging. I do take care with all my batteries, whether lithium ion or NiMH, to never discharge below 20% of capacity to avoid deep discharging, always use a smart rather than a cheap dumb charger to avoid overcharging, and try to avoid exposing them to extreme heat or cold (not always possible because of where I live and travel), which are some of the main factors that affect battery longevity, so no doubt this helps maintain their health and performance. Overall a great rechargeable battery that offers good value for the money.
