Informative Explanation of Features and Specifications of Both Products
CR2032 Battery
The CR2032 battery is a 3V lithium coin cell known for its robust energy capacity of approximately 220 mAh. Its dimensions are 20 mm in diameter and 3.2 mm in thickness, making it suitable for devices that have moderate space availability yet require a dependable power source. This battery is a popular choice in a variety of applications, including watches, calculators, and remote controls, due to its ability to deliver consistent power over time. Its high energy density and long shelf life also make it ideal for low-drain devices that are used sporadically but require reliable performance when in use.
CR1220 Battery
The CR1220 battery, while also operating at a voltage of 3V, is significantly smaller than the CR2032, with a diameter of 12 mm and a thickness of 2.0 mm. This compact size allows it to fit into devices where space is limited. However, its energy capacity is lower, ranging between 35 and 40 mAh. This battery is typically used in small electronics and motherboards, where the power demand is minimal, and the space constraints are significant. The CR1220s compact form factor and sufficient power delivery make it an ideal solution for maintaining functionality in miniature electronic components.
Differences Between Products
The primary differences between the CR2032 and CR1220 batteries stem from their size, capacity, and intended applications. The CR2032 is larger in both diameter and thickness, allowing it to store more energy, with a capacity of 220 mAh compared to the CR1220s 35-40 mAh. This makes the CR2032 better suited for devices that require a higher power output over a longer period.
In contrast, the CR1220, although smaller and less powerful, is designed for devices where minimizing space is essential. Its reduced size enables it to fit into smaller devices such as compact electronics and certain types of motherboards. The trade-off, however, is its lower energy capacity, which limits its use to applications where minimal power is sufficient. While both batteries operate at the same voltage of 3V, their distinct physical and capacity characteristics cater to different technological needs.
