Low internal resistance for fast flash charging times and quick shots. A long shelf life of up to 10 years. Powerful lithium technology that operates reliably even across a wide temperature range (-40 °C to +70 °C). Thanks to the use of lightweight materials, Panasonic's cylindrical CR123 lithium batteries are ideal for small cameras as well as portable lighting systems. The batteries can also be used in security devices, security sensors, and smoke detectors.

Cylindrical CR123 lithium batteries feature a spiral structure and enlarged surface areas of the positive and negative electrodes. This design allows for current draws of up to several amperes, which is very convenient for flashlights that require instant power. Panasonic's cylindrical CR123 lithium batteries contain manganese dioxide, a chemically very stable substance. Under suitable storage conditions, they retain 90% of their battery capacity even after ten years of storage. These batteries offer a structural design for optimal safety and stable substances for the active materials. They have undergone various safety tests, demonstrating their excellent safety. Panasonic's cylindrical CR123 lithium batteries have been certified according to the safety standard (UL1642) by UL (Underwriters Laboratories Inc.).
