Comparison Between Batteries
The 2CR5 battery is a larger design that combines two 3V cells to deliver a total of 6V, making it a better fit for devices that demand higher voltage.
This design difference is significant, as certain gadgets are equipped with a specific battery holder to accommodate the size difference, allowing them to use either one 2CR5 battery or two CR123A batteries placed side by side.
A key consideration is the voltage requirements of your device, as rechargeable CR123A batteries, called RCR123A batteries, typically operate at a higher voltage (7.2–7.4V) compared to the 6V provided by a 2CR5 battery.
This difference in voltage may cause compatibility issues or even damage to devices designed specifically for 2CR5 batteries, so it's essential to choose the right battery type for your device.
