Ⅰ.Introduction to CR2430

CR2430 is a lithium battery model. This type of battery usually has a rated voltage of 3V, a round shape, a diameter of 24mm and a thickness of 3.0mm. CR2430 batteries are a type of button battery, also known as button-type lithium batteries because their shape resembles the buttons used on clothing.

CR2430 is commonly used in small electronic devices such as watches, remote controls, calculators, medical equipment, and other devices that require small, lightweight power supplies. They provide relatively high voltage and stable power output while being small and lightweight. CR2430 battery is a non-rechargeable lithium battery. Once the power is exhausted, it usually needs to be replaced with a new battery.

Ⅱ.Introduction to CR2450

CR2450 button lithium manganese dioxide battery is named according to IEC standards. Among them, C- is a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode. CR- means that the shape of the battery is button-shaped.

Compared to the CR2430, the CR2450 is slightly thicker and therefore may contain more battery capacity, providing a longer lifespan. Likewise, when using CR2450 batteries, it is best to follow the manufacturer's usage and handling recommendations to ensure safety and optimal performance. Please note that specific product specifications and performance characteristics may vary by manufacturer.

2450 represents the standard size of the battery. The first two digits of the button battery name (one digit below 10mm) are the diameter, and the last two digits are the thickness. The 24 in 2450 means the diameter is 24mm, the 5 means the battery height is 5mm, and the 0 means the battery is cylindrical in shape.
