"I wanted a bunch of extra 18650 for flashlights but on a budget. I have never had a bad experience with Samsung Li batteries before. Button top and protected they made great backup batteries. They seem to hold a full charge for over 6 months. I simply put a few wraps of Super33 around them and put them in my pack and have light for many many nights without need to recharge."
