Hi, am very pleased with these batteries. Use for my key ring flashlight Olight of emergencies. In an emergency (at night in the forest run) has the battery proved to be very stable. If there is no emergency, then especially the resistance to aging or low self-discharge is important for me. I have for several months in a battery of my flashlight, I could find so far no performance penalty. The battery looks visually like new. According to the manufacturer to a storage of 10 years to be possible without any significant power is lost, the but I could not test, because I do not yet have the batteries for so long.
