is there a difference between cr123 and cr123a

CR123 and CR123A are often used interchangeably, but there is a slight difference between the two. The CR123A is a newer version of the CR123, and it has a higher capacity and better performance. CR123A batteries are designed to provide a longer operating life and better reliability in high-drain devices such as digital cameras, flashlights, and security systems. They are also more environmentally friendly, with a reduced impact on landfills due to their longer lifespan. Both CR123 and CR123A are lithium batteries and share the same dimensions, so they are physically interchangeable in devices. However, the CR123A offers improved performance and reliability, making it the preferred choice for high-drain devices. When shopping for batteries, it's important to consider the specific needs of your device and whether it can benefit from the improved performance of the CR123A.
