Lisun CR123A Lithium 3V Battery
A CR123 lithium battery is a specialized Lithium-Metal disposable (primary) 3 Volt battery. It uses manganese dioxide, MnO2, as its primary cathode material. The small size makes it perfect for digital and film photography (cameras and flash units), high-lumen flashlights, and other portable electronic equipment. Disposable (primary) lithium batteries are not rechargeable. Rechargeable lithium-ion batteries have either lithium-ion or lithium-polymer chemistries.
